1. Aquarium Lighting Glossary

Aquarium lighting has many purposes, from basic illumination, to color enhancing, to providing energy for photosynthesis. Here are the definitions to some commonly used terms, to help you better understand aquarium lighting.There are a few terms that you will commonly come across when you are looking at Aquarium Lighting Systems , and Aquarium Bulbs & Lamps . This is a brief glossary of these common terms, to help you better understand the terminology, and help you purchase the proper products for your aquarium.The power rating for aquarium lamps and bulbs, shown in Watts, can be looked at as a measure of both the power consumption and output of a light bulb. The higher the wattage, the higher the energy consumption, and with respect to each type of light bulb, generally the higher the wattage, the higher the output of the light bulb. Newer technologies, such as LED Lighting , produce much more light output per Watt, versus older technologies. Light fixtures are designed to use a specific type and wattage of bulb, and should always be replaced with the same.Without getting too technical, Kelvin rating is a numeric scale that describes the color of an object at a given temperature. For aquarium purposes Kelvin rating describes the color, or spectrum, of sunlight in a given environment. For example, the approximate Kelvin Rating of tropical sunlight at sea level is 5500K. Sunlight is comprised of many wavelengths of light, which combine to produce the "white" light that we see on the surface. As light enters water, the different wavelengths of light penetrate differently, and are filtered out as depth increases, and the Kelvin color rating changes. The deeper you go into the water column the higher the Kelvin Rating becomes. 20,000K light bulbs are designed to mimic deep water environments, and are very blue in appearance. Daylight spectrum (5000K-6700k) bulbs are ideal for freshwater aquariums with live plants, higher Kelvin bulbs (6700K-20000K) are ideal for saltwater aquariums.For Aquarium purposes, the term Actinic is used to describe the blue spectrum of light, from about 420nm - 460nm, which is beneficial to photosynthetic corals and invertebrates. Actinic light will also enhance fluorescence in the tissues of corals, fish, and other objects with fluorescent pigments. Actinic lights are commonly used to enhance colors, as well as simulate dawn and dusk lighting schemes in marine aquariums, but can also be used in freshwater aquariums to enhance the colors of certain fish. Blue light penetrates the deepest into the water column, actinic lights are used to help simulate deep water environments.T rating refers to the diameter of Fluorescent light bulbs, the scale is based upon 1/8of an inch. For example, a bulb with a T8 rating has a diameter of 1 inch. The two most common aquarium bulbs are the T5 and T8 bulbs (T12 bulbs have been discontinued). T5 and T8 fluorescent bulbs have different pin spacing and wattage, they are not interchangeable.The Ballast is the electrical component of a fluorescent or metal halide lighting system, which converts the incoming electrical supply, into a form that enables the light bulbs or lamps to produce light. Ballasts are specific, for specific types of bulbs, and must be matched accordingly. Ballasts can be internal or external to a light fixture, and can be included in a lighting system, or sold separately as part of a kit or replacement part.

2. Does this sound like a good idea?

Most of it sounds good; but running a gas generator is NOT a good idea. Where any given amount of electricity might cost you pennies, the same generated from gas can cost you dollars. BAD choice. Since you are interested in learning: experiment with solar power and maybe wind power too. Since it's a small cabin, you can probably power it from a 120 amp car alternator and a couple batteries charged either by wind or solar. Use a 12 volt 2000 watt inverter, and use it ONLY when needed. The batteries can spend the day charging from solar or wind. At night when you need a little light, be practical, use LED lighting. They make LED car lights such s turn signals and stuff, not real expensive, so you wo not need to run the inverter either. You will need to run the inverter for the refrigerator or the microwave, but aside from that, your lighting can be handled by low power LED's. But what are you going to do for heat? Fireplace??? Not so efficient either. But I am not here to give you ALL the answers, you should do some more research. Also consider running water and how you might heat that. Good luck. ")

3. Does light pollution affect astronomers?

Yes, light pollution does affect astronomers-especially amateurs. We've been able to get some fantastic photos even from our urban and suburban backyards and driveways especially by using narrowband filters that block out stray light from sodium and mercury streetlamps. But recent adoption of LED street and home security lighting is making this more difficult. LED lighting is broad spectrum white light illumination, so the narrow band filters are not effective against them. And, in my opinion, the LED lighting is also way brighter than necessary for outdoor illumination. Much of this lighting is wastefully directed towards the sky instead of just the ground. Photos from space-historic and recent-show that ground lighting has become brighter and whiter than in the past. For more information, see Light pollution - WikipediaDoes light pollution affect astronomers?

New Location, Cause for Hemp & Co.
The space is newer and greener and Hemp & Company has decided to use its new Government Street digs as a launch pad for a new environmental award.The 15-year-old Victoria retailer, which works to expand awareness of organic and eco-friendly clothing, nutrition and bodycare, has launched the Eco-Hero contest in order to shine a light on entrepreneurs, volunteers and community leaders who make a positive mark on the environmental landscape."We wanted to recognize people who are involved in environmental issues and we thought what would be a good way to support them and get the community thinking," said Bill Finley, who runs Hemp & Company with wife Lorna Knowles. The company will be taking nominations until Nov. 23 for individuals and then the community will be able to vote for their favourite between Dec. 1 and Jan. 31. The winner will be announced Feb. 5 and will win an "awardrobe" of Hemp & Company gear."There are not many initiatives likes this, that award eco-heroes," said Jill Doucette, founder of Synergy Enterprises, a firm that works with companies to improve their green practices and worked with Hemp & Company to develop the award idea.Doucette said the contest will mean environmental leaders are profiled in the community and lauded for what they do, whether it be land conservation, developing innovative technology or rallying the community behind a cause."Hemp & Company loved the idea of connecting with environmentalists that share their vision," she said.Finley said that environmental bent is a huge driver behind the store, now open at 1312 Government St., two blocks from the old location at the corner of Government and Fort streets."I'm an environmentalist more than anything else. I've been on the protests and hugged the trees and all that and it's all well and good, but I always felt a little unsettled as it wasn't proactive," he said. "This business came along through my son [Mike Finley] and it felt like a business where you could do something and hopefully make a difference in the world." The new store makes a difference as well. It is smaller than the last locations. It has 1,300 square feet of retail space and includes a number of features that "green" the place up.The work and lease-hold improvements on the space within the newly renovated New England Hotel, an 1865 building, led to the company recording the highest score for a retail business on the Island from the Vancouver Island Green Business Certification program."When I completed the assessment at Hemp & Company, I was truly impressed," said VIGBC program manager Craig Sorochan. "They have integrated sustainability into everything from their light fixtures and flooring to the products on their shelves." Finley said most of the initiatives had been done in the old store as well - a heavy-duty recycling program, no plastic bags and the like. But the new store also includes wood reclaimed from an old aircraft hangar in Comox used for flooring, recycled lighting fixtures, LED lighting and a heat pump for heating and air conditioning."We thought of all the things we could and did whatever we could within the fine budget we had to create a space that was as green as the products we are selling," he said.Doucette said the company has been a "long-standing pioneer of environmental initiatives and products. They have always been on that cutting edge of the next environmental solutions and very supportive of local business."
LED Lighting Is the Prime Choice of Interior Decorators
The growth of technology and necessity of better light sources gave us LED lights. The sources have evolved from the traditional incandescent or fluorescent lights to LED. Compared to incandescent lights, LED lights have the lighting consume 60% less energy and provide similar brightness. The architects and interiors designers are now having much better options with LED under interior lighting. They can now experiment a lot of new looks because the LED flexible strip can be operated on ultra narrow platforms. The LED strip lights can be installed anywhere without much of a trouble and produces warm or pure white light. They are extremely low profile and highly flexible to be bent in any degree. The LED lighting can be installed in many ways with the help of fixtures and give a much better glowing effect in the surroundings.The LED lights are widely used to enhance the look of the home or office. It is luxury form of LED interior lighting because they give a whole new outlook to the space where it is installed. The contractors and architects today use variations in the lighting to give attractive look. It is available in vivid colors; hence they can be used to suit the mood better according to the environment and color theme of the surroundings. They also give the facility to be modulated; hence the brightness can be controlled. This complements the area which is illuminated and hence has gone a step ahead as compared to xenon or incandescent lighting. The interior decorators always use new & better options to decorate the home, office or hotels. Be it a book shelf, garden patio, kitchen cabinets or ceilings, LED has become their prime choice because of brilliant color combination, less heat generation and low consumption. The LED flexible strip lighting can be accommodated anywhere without much of an effort.The LED interior lighting has become the first choice for many to highlight other sophisticated furniture. The dug in LED under cabinet lights are placed directly into the cabinet or shelf making them non noticeable. The LEDs are primarily installed in living room area for maintaining more artistic interiors. The LED lights can be installed in process hence the area should be chosen extremely wisely during installation. LED lights are also available in flexible strip and aluminium tube format that can be used in interiors for highlighting purposes. These LED aluminium tube lights operate on a remarkably less power. The LED tube lighting offers a variety of colors and can have their brightness modulated with dimmer as required. LED lighting can be used in extremely narrow spaces and still give the required luminance. The lights come as a bar or disk and can be chosen according to the requirement and the space available. The decorators also utilize the accent lighting to enhance the look and highlight the counter tops with LED lights. The LED lighting is also used as jewellery display lights because of their flicker free nature and no maintenance.Tired of traditional lamps that do not provide you eco-friendly lights, and consume so much energy as well?

Light Quality Is Critical to Strengthen Adoption of LED Lighting-Made-in-China.com
To provide a more balanced portfolio of ENERGY STAR lamp products on the market and mitigate color quality as a barrier to wider adoption of energy efficient lighting products, Soraa proposed to the EPA a second high CRI tier with differential efficacy requirements taking into account the inherent lumen per watt trade-off as a function of CRI for phosphor converted white LEDs. Soraa proposed to keep the existing minimum efficacy requirements, but raise the color quality to a minimum CRI 90. For lamps with CRI between 80 and 90, Soraa proposes to increase the luminous efficacy requirements.Poll: Last time you cried ?I am crying as I type thisHave you ever cried because of a song?weirdly yes haha Hurt- Christina Aguilara the music video made me cry hysterically >What movies have you cried during?I am a guy and straight so yah my tears do not fall as easily.

RDECOM Soldier Center's Bright Idea for Lighting System Improves Illumination, Saves Energy
NATICK, Mass. -- The Research, Development and Engineering Command Soldier Center's Expeditionary Maneuver Support Directorate, or EMSD, has developed a new lighting technology that provides better illumination while using less energy than fluorescent tube lighting. Under a Cooperative Research and Development Agreement with Southern Cross Printed Electronics, Australia, and its U.S. representative BAM International, EMSD developed the Flexible Light Emitting Diode, or LED, Lighting System, which is also called MFLEX. The MFLEX system is part of EMSD's ongoing commitment to improving energy efficiency and reducing the logistical footprint of expeditionary base camps. "Although there are several alternative LED lighting solutions available to the warfighter, all of which provide the benefit of saving energy, which ultimately translates into fewer or smaller supply convoys, the major benefits of these lights are reflected in three measures: 1) the amount of time necessary to setup and takedown a tent, 2) the transportation weight and volume, and 3) the quality of the lighting," said Melvin Jee, leader of the Soldier Center's EMSD's Expeditionary Command Platforms Branch. The Flexible LED Lighting System will replace the fluorescent tube lighting commonly used in the field. The system can be used in virtually any size tent, provides more illumination, and greatly reduces shadow area when compared to fluorescent tube lighting. "The flexible LED lights provide fairly even illumination, virtually eliminating heavy shadow areas, making the environment more comfortable for the warfighter by reducing fatigue due to eye strain," said Jee. By improving illumination and reducing the presence of shadows inside the tent, the system helps facilitate command and control functions. Soldiers often carry out various aspects of mission planning while in tents, including looking at maps and other information, and the improved illumination and reduction of shadows may help them better perform such tasks. Moreover, the system is more compact and weighs significantly less than fluorescent tube lighting. The Flexible LED Lighting System fits into a backpack-sized bag. This one small bag replaces up to four transit cases needed to light a single tent with fluorescent lighting. The cases weigh between 40 to 50 pounds each, compared with the backpack-sized bag needed for LED lighting, which weighs only 10 pounds. The backpack-size bag contains 12 meters of flexible LED lighting, complete with cables and hangers. The bag also contains the power supply and control circuitry, which allows the lights to be dimmed and/or switched from white light to blue/green blackout light. Warfighters do not require a specific Military Occupational Specialty, or MOS, to install and operate the lighting system. The LED system does not have to be taken down when moving to a new location, increasing ease of mobility and reducing setup and tear-down times. The system is being used by the 82nd Airborne Division. The Soldier Center has partnered extensively with the 82nd Airborne to gain insights into improving and developing appropriate tools, techniques, products and technologies for the warfighter. The division's feedback/input helped to shape the development of the Flexible Light Emitting Diode Lighting System. The U.S. Army Soldier Center is part of the U.S. Army Research, Development and Engineering Command, which has the mission to provide innovative research, development and engineering to produce capabilities that provide decisive overmatch to the Army against the complexities of the current and future operating environments in support of the joint warfighter and the nation. RDECOM is a major subordinate command of the U.S. Army Materiel Command.1. Cost vs Power: Checking out Some LED Lighting SolutionsEver wondered about the size of a salt grain? A single salt grain measures about three mil, which is a thousandth of an inch. Now, imagine a third of that size, placed on a printed circuit board (PCB). That is the size of the smallest LED available today. People do not regularly go for it, but it is heartening to know that something that small can also brighten something up. That is where the surface-mount device light-emitting diode (SMD LED) module comes into the picture. Now, you have a 0.65mm0.35mm0.2mm-size LED on a PCB that can be used for a range of different purposes. Wide viewing angles of about 145 and low power consumption add to the charm. An SMD chip is created from layers of man-made nano-sapphire and gallium crystal substrates. After growing these crystals, these are sliced, layered and bonded to a ceramic base. The chip can be then mounted in the required application. Applications of an SMD include everything from light bulbs to strip lights. One interesting use case would be the indicators on mobile phones. Over the years, SMD LED has continued to improve its luminescence in accordance with Haitz law. If a chip includes red, green and blue diodes, you have the possibility of creating any colour you want. This has resulted in SMDs becoming the prime choice for DC power applications, mostly due to the ease of use. A COB LED has great advantages of thermal resistance, larger cooling area, better lighting effect and high light efficacy. It is basically an LED built directly on the circuit board. P. Chow Reddy, managing director, Interleaved Technologies, explains, "A COB contains multiple chips within one large wafer. This allows a larger light output and a more even spread of light." It allows connection of the bare chip to the substrate by conductive or non-conductive adhesive and wire bonding to achieve its electrical connection. Due to fewer components in the LED chip, thermal conductivity is directed at the circuit board and without the traditional LED chip packaging structure. Heat emissions from LED chips are on average 25 per cent lower as compared to conventional LEDs, resulting in high efficiency and lower failure rates. And since the chip is built directly onto the circuit board, it reduces the need for spot soldering. After all, fewer soldering points mean less chances of failure. Need for traditional LED packaging parts and PC lenses has also reduced, resulting in an increase in light visibility range and a decrease in light loss from lenses. COB LEDs are generally larger than SMDs and range from a few millimetres to a few centimetres-square. At this small size, soldering these to the board becomes a problem. COBs are easier to place on a board. The pins in SMD require precision soldering An evolution over the conventional COB is the multi-chip-on-board (MCOB), for when one is not enough. It consists of multiple chips integrated into one larger single board. Assembly is cheaper compared to multiple single chips, making these suitable for applications in streetlights and high-bay lights. However, there is still some time before these can be used in smaller applications. Sharp Devices, Europe, recently announced a range of high-performance mini and mega zenigata COB LEDs with greater efficiency and enhanced hot lumen performance. HD6 mini zenigata are 12mm15mm with an 8mm light-emitting surface with 2500 lumens. BF6 series mega zenigata are sized at 20mm24mm substrate with 15mm light-emitting surface. Recently released are another two new blue LED chips from Light Avenue in 12V and 24V. Both solutions are sized at 140 mil to increase implementation in tracklights or high-bay lighting. Small-sized chips are clustered and packaged into a light bulb that is advertised as 'lighting always' or 'save power now.' Some LED manufacturers are able to reach 249 lumens per watt with a 20mA supply. However, this is not the story with bigger sizes. Light efficiency follows an inverse relation with chip size. Additionally, with an increase in current to the LED, efficiency is further reduced. One of the best things with the use of SMD and COB LEDs is that now you can get a much better looking LED display without having to pay as much for it-this brings in the matter of dual-in-line package (DIP) LEDs going out of fashion. DIPs have been around for more than 50 years, and are likely what you think of when you picture an LED. Though easy to use, these are much less efficient over other available options, and hence the reduced usage.2. Controlling light colour with DALIWhen planning lighting control with DALI, the focus nowadays is often on the pure function. Within HCL (Human Centric Lighting) there is frequently a demand for control of the colour temperature of accent lighting with saturated light colours. During the planning phase the user should always bear simple maintenance of the lighting installation in mind. It saves time and money if you can make adjustments yourself. But to do this you need expert knowledge. DALI is the standardized lighting interface in IEC 62386. Compatible devices are low in price, robust and easily available. There are stand-alone DALI lighting controls and numerous Gateway solutions in nearly all relevant building automation systems. For this reason DALI is aways a point of discussion in nearly every planning project for large functional buildings. However, even in the residential sector DALI is being used more and more, since, precisely when it comes to LED lighting, the function is guaranteed by being integrated directly in the DALI luminaires. There is no longer any need for complex compatible combinations of LED power supply, LED dimmer and LED module. The relevant functions are already integrated into the control gear. The strength of DALI becomes especially appparent with colour-variable luminaire combinations. DALI control gears are classified as standard in different types of device. LED control gears and luminaires are assigned to device type 6. Device type 8 is for colour-controllable luminaires. Colour control is standardized in DALI, which is especially important when colour control should span devices from different manufacturers to ensure that all the luminaires emit the correct light colour in the required intensity. It is possible to control in the brightness of luminaires in different ways using broadcast control or group and scene control. DALI operates according to the Master/Slave principle. The master can be a simple broadcast control device, such as the rotary control knob which can make a luminaire brighter or darker. The Master can however also represent complex lighting control. This might consist of many elements which communicate with each other in a superordinated network. If one DALI device fails, all project data previously saved, such as group membership, fading times or scene values have to be restored. In broadcast control all the luminaires which are physically connected to each other are triggered simultaneously with direct brightness values. In the DALI standard a broadcast address is set by default. All DALI luminaires obey commands which are broadcast-addressed, whatever address they themselves possess. Thus, it is not necessary to address and configure the luminaires. Faulty control gears can be replaced easily by new ones. In group and scene control the group allocation and the light scene values are stored in the control gear. The same is true for further parameters. Then the luminaires have to be addressed. When commissioning this is very complex because the luminaires must first be identified and then configured. As a rule, configuration of a DALI line is performed by the Master via PC software according to the principle of random address allocation. For DALI colour control with the conventional DT0 (fluorescent lamp) or DT6 (LED) a DALI address is required for each. The DALI luminaires have to addressed and grouped. The colour is defined via value control via several DALI addresses. When such a lighting solution is dimmed, the colour information is lost and commissioning is very time-consuming.3. How can I mount an 12V transformer for LED lighting inside a wall?You can not apply the low-voltage rules to transformers. Because half of the transformer is not low voltage, it is mains voltage. Anyway, you are talking about LED drivers or power supplies, not transformers. (a transformer is a real thing, it is a different thing.) Also, remember, the easy Class II rules for low voltage circuits do not apply if the circuit is over 55 watts
KMC Eyes Solar, LED Lighting for EM Bypass and Maa | Kolkata News - Times of India
Kolkata: The Kolkata Municipal Corporation (KMC) is taking a major step to turn green compliant. After the successful installation of solar lights at Deshapriya Park, the civic authorities are now working on plans to convert all street-lights into solar and LED on the EM Bypass stretch from Patuli to Ultadanga and on the Maa flyover stretch under the 'Green Cities' scheme which would help the civic authorities save Rs 4 crore electricity bill annually. Solar power expert and former managing director of West Bengal Green Energy Development Corporation S P Gon Chaudhuri has handed over the detail project report to MMiC (parks and gardens) Debashis Kumar at the KMC headquarters. "The proposal is to install solar power panels and LED panels on the entire stretch of EM Bypass and Maa flyover. It is a Rs 22-crore proposal in which 1.2 MW of solar power would be generated daily. The civic authorities would be able to save Rs 4 crore electricity bill per annum and this will also help reduce 12 tonne of CO2 emission per day," Gon Chaudhuri said. The other proposal that Gon Chaudhuri has handed over is to harvest 1.5 MW solar power from the Dhapa garbage field by setting up a solar plant. The solar panels here will be installed at a height of 10ft and vegetable cultivation could be done as well under the solar panels. This will ensure more moisture in the soil during summer. Kumar said the project will be taken under the state government's Green Cities Mission. "We had asked Gon Chaudhuri to prepare the report which we have received. It seems to be a very good project which will minimise our electricity cost and will also pave the way for a greener city," Kumar said. A total of Rs 40 crore will be spent under the scheme. After the installation of solar lights at Deshapriya Park, KMC authorities noticed a drastic 80% fall in electricity bill in the area.

It produces bright and effective light.There are many companies who are using it in their business in a multitude of ways, from marketing to retail to energy saving applications. They are leading the way and taking the lead in this as well as other sectors where LED has shown its benefits.Street lights are crucial for safety as well as for visibility. Since the lighting process is an important part of the street lighting scheme, it is important to choose LED lights that will last longer and provide better light output.LED lighting is one of the most cost effective options for street lighting. However, it is not suitable for everything and needs a little customization. In this post we will show how to select the LED street lights based on your business needs and target audience.LED Road Street Light was a revolutionary invention that led to the development of LED lighting. It brought many benefits but also came with some disadvantages.For example, when it comes to outdoor lighting, there are still many places where LED lights are not permitted. For example, in some countries, it is prohibited to use LED lights on office buildings because of health and safety reasons.While the benefits of LED light could have made this product successful in the market, its disadvantages were also responsible for its downfall. When you compare it with other major brands such as Incandescent (generally considered as a good light source), CFL (considered as best choice for outdoor lighting), or PAR lamps (generally considered as the ideal indoor light source), then there is no doubt that LEDs are a better option than halLED road street lights are a big part of city traffic, and they're also very useful for different purposes. However, the lights have an annoying problem: some of them are dimmer than others. In order to find the best one, we need to get a lot of information about LED road street lights.Street lighting is mostly about the LED lights. However, there are many other options such as solar powered light bulbs and sodium vapor lamps.We have to look at the current generation of LED lights and their advantages/disadvantages. Some of them can be used in areas that require street lighting, while others are not suitable for street illumination such as urban areas with high pedestrian traffic or traffic-clogged roads. There are also some options that can only be used in countries with specific regulations, so it is difficult to use them outside those zones.LED lamp is getting popular through the recent years. This article will help you make a decision on which type of LED Road Lighting is best for the street lighting system.It was found that a lot of people are living in cities and they have to face the problem of poor street lighting every day. This might be due to issues like pollution, traffic, etc. This article will try to help you decide on which kind of LED Street Lighting system can be applied in your city or neighborhood and give you information about different types of LED Road Lamps available in market today.LED lights are cheap, clean and energy efficient.We are currently using traditional street lighting systems that generate electricity either from overhead power lines or from large generators. The connections to the grid are a lot of wires, many of which are fragile and can be damaged. Also the wiring is not as flexible as it should be to allow for dynamic adjustments in light intensity, angle and even colour due to wind conditions and weather. LED lights could solve these issues by allowing us to move lights around on rooftops without having to rewire existing infrastructure, they allow us to adjust the light bulbs at will also by moving them around the roof (perhaps with a remote control) which means we can change lighting intensity for our vehicles without having to stop traffic or make repairs on the road.LED street lights are a great energy saver but they can be very expensive. They consume a lot of electricity and in the end they don't last as long as traditional street lights. Hence, using LED street lights is not cost-effective.A bright LED bulb costs less than an incandescent bulb and yet the light produced by them is about half that of a conventional light bulb. And thanks to the cool white color, it can effectively illuminate up to 20,000 square feet without needing to turn on any additional lamps or fixtures.

As a matter of fact, now is exactly the time to start plotting (and potting.) what bulbs you want to plant. Some of the most beautiful plants that bloom each spring-daffodils, tulips, and Dahlias, for example-need to be planted in the fall in order to give them enough time to bloom in the spring. So how can you get the best results from your bulbs to have a stunning yard next year? The Maryland landscaping experts at Four Season are here to help. So you want to plant bulbs. Getting them to bloom so you can have a beautiful lawn is not difficult, you just have to follow the right steps and plan ahead. So how can you have a stunning lawn in time for next spring? Here are some tips to get you ready: • Timing is everything. Like anything in life, timing your bulb planting is essential. So when's the best time to plant your bulbs? You should start your plantings roughly six months out from spring. However, this is not an iron clad rule-there are mitigating factors to consider. • Check the temperature. When you are planting your bulbs, you need to make sure the soil temperature is cool enough. Bulbs are at their happiest when the soil temperature is between 40 and 50 degrees Fahrenheit. A good rule of thumb is to wait for the first frost, which in Maryland is usually between early October and early November. • Watch for sunlight. Bulbs like the sun-no shock there. So when you are planting them, plan in advance for the spring. Make sure your plants will get good sunlight. That mostly means avoiding the shadows of your house and other landscaping features. Since most trees wo not have leaves when your bulbs sprout, you wo not have to worry too much about tree cover being an issue. • Check for moisture. Plants like to stay dry. When planting your bulbs, make sure you have soil that drains well. If not, the bulbs could rot and not sprout. When planting your bulbs, make sure you dig a hole between 5 and 8 inches deep. Err on the lower side for small bulbs and vice versa for larger ones. The first year you plant bulbs, they wo not need any special fertilizer or plant food, but if you plant a perennial bulb, you will need cow manure to cover the top layer of soil after the flowers die for the season. You can pick this up at any gardening center, and it will keep your bulbs happy for years to come. Four Seasons' nursery has all the best plants for your Maryland garden.light bulbs?They are a little spendy but use the GE Crystal clear bulbs. Not only are you getting natural yellow light but since the bulbs are not frosted they give off more light. This means that where you used two 60 watt bulbs, you can now use two 40's and still light the room quite well. Saves energy and they just look cooler tooHalogen Bulb?A 20W halogen bulb is just over 100W in an incandescent bulb. I believe the 14W halogen is closer to the 100W incandescent . so it would be between 100-150W in an incandescent bulb.is a fluorescent bulb the same as uvb bulb?There are fluorescent "tubes" that produce UVA/B light but not ALL will. It will say on the box whether or not it produces UVA/B light. Also, there are huge arguments as to exactly what type of light produces the best UVA/B output. You can post another question about that if you likeDo tulip bulbs make more bulbs?i am not sure about the tulips but if you are looking for a flower that will mulitply then lillies are really good i planted one in 2007 then last year when they came back i had 11 stems come up and i was able to split them up and have 11 seperate lillies, if you do that you have to make sure that when you split them up that you take one of the bulbs with the stem try going on a website about tulips all you have to do is type in tulips and that will get you the info you need

What led up to it?When I was 17 years old I gave them my fingerprints. I figured if I was not doing anything wrong and I ever got in trouble it might help. I was not thinking clearly, and not just because of who my dad was. A few years later I wound up in Mental Health for not thinking clearly. It took me many many years to recover. Would I give my fingerprints to the FBI now? Probably not, or if I did I would realize it could do me just as much harm. That's not to say I would not do the same if I was 17 years old though. The problem was not that I gave the FBI my fingerprints. No the problem was that I was not using good senseHas the reduction in children's play time outside led to an increase in mental health issues?This is not something I specialize in however it is proven that kids are spending less time outside, making less childhood decions for themselves and metal health problem is on the rise. Now that's not saying WHY this is happening .. for instance if a child is overloaded with school work it could very easy be the simply do not have time for anything other than homework. . is it because of video games? Or something else.. everyone even professional has thier own oppion and facts are pointing to all kinds of reasons why children just are not out playing.. not to mention society has changed from the days kids were out playing all the time.How do I get over a guy friend who led me on?You both lead each other on.One of the things for low self image is a person waits for someone else to do something and not be direct. They always waiting for someone else to say and do. They wait and wait and wait when they too have a choice to be direct. Then when nothing happens they behave as victims, blaming someone else on how the person used them and how they were lead on.You lead him on as well.You weren't honest either.You weren't direct and so that's why time went by and let someone else, your head up. If you don't have boundaries and if you wait for things to happen then you waste time. If you be direct then you polarise the person to quickly show their intent and if it's not good enough....you immediately walk away.So you are also responsible for showing vulnerability and being direct.You weren't because you fear rejection and so, embrace the part that he didn't lead you on. You liked the attention. You craved for it. But you feared losing it too and that is why you weren't direct with him for you to be lead on.Both of you then lead each other on.Both used each other for some craving and emotional stimulationWiring led's to xbox 360 help?dont worry about watts, those will never exceed the voltage from your xbox seeing it gets electricity from your outlet, which is attached to a grid. your safe. get a sautering iron or pen i prefer pen, and place the led on the silver metallic square, sauter until the metal is liquid and place led on. it will take 2 seconds to turn solid and there you go.Have you ever led a double life?
