Short Sound When Toggling a Light Indicator

The click is likely a bimetalic strip that turns on or off the oven heater. The light is also attached to the same heater circuit so gets switched on or off. Devices in this decade still have them as they are the cheapest way to control high wattage heaters. The "led" is likely only a neon bulb, or if indeed a led, it is often connected with just a current limiting resistor

What size wire and breaker do I need for my shed/workshop?

You will not be using everything all at the same time. So I would look at the nameplate Full Load Amps of your largest load, probably the table saw, plus any other things that might be running at the same time, such as the dust collector, lights and if the compressor is on a demand pressure switch, add that too because it might come one without you turning it on. Then add another 25% for good measure

What's wrong with my IR sensor

The answer I've accepted is the correct answer, but I wanted to add this extra bit for completeness. I reworked my code to use non-blocking delays for the IR LED so the sensor actually gets a chance to see it before it stops transmitting and it works! Range is quite a bit shorter than the 'lucky dip' sensor ( 2cm).Every time I use delay() (or delayMicroseconds()) I find a new reason not to!.

Led lights for live events

LED modules often require an external driver circuit to limit the current.

A PIR has a pyro-electric sensor, filter, and Fresnel lens that is designed to detect the IR from a human body, which has a wavelength of 5um to 10um.

adding a push button on LED string lights

yes, that button will work with those lamps.Just cut one of the wires between the batteries and the LEDs and connect each end end to a different terminal on the button. soldering is probably the best way to make that connection.

Problem with delay before LED turns on

The obvious answer is to use a small microcontroller. That will be a lot fewer parts than trying to do this in analog. You can then also arbitrarily program the delays. You only need a micro with 4 output pins and preferably a internal oscillator to make the circuit simple. I'd use one of the PIC 12F parts. These come in 8 pin packages and have up to 5 output pins, which is one more than you need

Dimmable LED lights flashing on full power

The flashing sounds like it may be the result of some capacitance that is getting charged and discharged at full voltage. AC transformers have capacitors in them in order to smooth out the waveform (process called rectification). The dim setting might be working at a lower voltage and the power supply struggles to provide the power at full 24VDC. Try measuring the voltage on the power supply, you may have gotten a defective unit

Keep it closer to 10-15mA

How to Fix Dc 12 Led Lights That Burn Out Due to Excess Voltage Or Current
Unfortunately you do not tell us how much current is needed by your LEDs and fans.Assuming that this current is less than 2 A you could consider using a buck-boost converter like this:In the description this model is listed as usable up to 3 A but you have to take that with a grain of salt. I would use it up to 1 A and not be worried. Maybe it would survive 2 A just fine, At 3 A it might get too hot and not work in the long run. Then it would be better to use a module rated for 5 A.Actually the name is wrong as the converter first boosts the voltage up to for example 24 V and then uses a DCDC down converter (a buck converter) to lower the voltage to the voltage you need, for example 12 V.This means the module will output 12 V as long as the input voltage stays within (quite broad) limits. So even at 10. 5 V or 15 V at the input, you will always get 12 V at the output.There are many different modules similar to this one, just search for "Buck boost module"1.

Are Fluorescent & LED Lights Making You Tired?
Did you know: some of the lights you have in your house are damaging your mitochondria (and thus adding to your fatigue)?Your mitochondria are so attuned with your environment that even the types of light you are exposed to each day can cause fatigue! The "bad" light I'm referring to here is a modern-day invention. Some refer to it as junk light. Others as white or blue light.The mitochondrial damaging light is a recent development for the human species. I'm referring specifically to compact fluorescent bulbs and the new LED (light emitting diode) bulbs - yes those same ones that last for years and years. These bulbs contain specific wavelengths of light that are particularly damaging to your mitochondria.And as I hope you know, underfunctioning and/or damaged mitochondria results in fatigue.Your body on lightYour ancestors had been exposed to the same type of light (the sun) for millions of years. (1) Millions of years! That is an incredibly long time for your body to adapt to one type of light. Through the sun, your mitochondria are best able to absorb and utilize light. They struggle when exposed to modern-day lighting.The compact fluorescent light was invented in 1976 and made its way into houses and offices in the 1980s. (2) Compact fluorescent bulbs are the spiral bulbs like the one found in the picture at the top of this post. The fluorescent tube lights - the ones you commonly see in office spaces - began being sold in 1938. Making their way into most offices by the 1950s. (3)LEDs (light emitting diodes) are the most recent lights to enter the commercial market. They were developed in the 1990s and only became affordable in the past few years. (4) LEDs are adored for their long lifespan - lasting ten times longer than incandescent bulbs. More recently, it's these bulbs that come enabled with wifi; allowing you to adjust the brightness with your phone.For millions of years, your ancestors were only exposed to the wavelengths of light put forth by the sun. In the early 1900s, the incandescent light bulb changed that. Humans were able to illuminate the dark. Fortunately, the wavelengths found in the incandescent light bulb were not too far off from that of the sun.It is the compact fluorescent (CFL) and LED bulbs that affect your mitochondria in a very bad way. These lights lack the wavelengths/frequencies found in natural sunlight. The infrared, red, and violet wavelengths found in sunlight are completely eliminated from LEDs and CFLs. And the blue light frequency has been amplified.Take a look at an old-fashioned incandescent light bulb. Notice how the light emitted has a warm orange/red/yellow color to it. These are the red, infrared, and violet wavelengths being expressed. Now, look at an LED or CFL. Notice how that light looks blue and white, and it's almost irritatingly bright - this is the blue wavelength predominantly expressed.Your genes have been exposed to sunlight for millions of years. And to blue light for less than thirty years. Your genes have not adapted to this modern, artificial light. And because of it, your mitochondria are suffering. This is how something seemingly as benign as the lights in your house could actually be adding to your fatigue.Shedding some light on your mitochondriaYour mitochondria are your body's power plants. These tiny structures, found within nearly every cell in your body, produce a substance called ATP (adenosine triphosphate). And ATP is the energy that powers your body.Those with chronic fatigue syndrome and/or myalgic encephalomyelitis have a reduced functioning of their mitochondria. This results in a net energy deficit. (5) In order to increase your energy and overcome fatigue, you need to optimize your mitochondrial function.And the lighting you use in your environment is the perfect place to start.Just like you, your mitochondria have evolved over millions of years to utilize the energy of the sun. They have not adapted to utilizing the blue wavelengths found in modern daylight sources.One study showed that after only six hours of exposure to blue light, mitochondria were not able to produce energy as efficiently. As exposure time increased beyond six hours, mitochondrial function continued to decline. (6) It is hypothesized that exposure to blue light increases cellular aging and age-related illness. This occurs because blue light is thought to damage the DNA of your mitochondria.Suffice it to say that if you're dealing with fatigue, you need to minimize your exposure to blue light. But what do you use for lighting then?How to avoid blue lightIf you have chronic fatigue syndrome, the very first thing you need to do is ensure your home (and hopefully your office) are free from LEDs and CFLs. Replace these bulbs with incandescents. The small amount of money you save on your energy bill using CFLs or LEDs is not worth the cost to your mitochondria.If you work in an office where you don't have control of the lighting, you're going to need to be extra vigilant. To combat blue light exposure, you need to increase your exposure to red light sources. Your best bet will be getting outside every chance you get.Take your coffee break outdoors. Go for a walk at lunch. Look out a well-lit window. Try to get outside when the sun is at its zenith in the midday. Stay outside for at least fifteen minutes, ensuring you have as much skin exposed to the sun as comfortable.What do you do if you live at a latitude that results in very cold temperatures for half the year? Or, if you live in an area constantly covered by clouds?You're going to need to utilize technology to increase your red light exposure. In the morning, expose your body to an ultraviolet sun lamp. I recommend spending 10-15 minutes each morning during the winter months in front of it. While working in your office, invest in some red LEDs. These will ensure your mitochondria get exposed to the red wavelength during the day. This simple act will improve your mitochondrial function and in turn increase your energy levels.While the type of light is indeed very important, the time in which your body gets exposed to light is equally important.AM light and PM lightDo you hit the snooze button 10 times each morning?This morning fatigue is often caused by a suppression in your cortisol awakening response (CAR). The cortisol awakening response is a surge in your cortisol levels shortly after waking. It is this surge in cortisol that should energize you to get out of bed in the morning.In order to trigger a healthy CAR, you need to get exposed to sunlight immediately after waking. If you live at a latitude that results in a sunrise well after your alarm, you need to invest in a full spectrum UV light. Turn your UV light on immediately after your alarm goes off. This will mimic a sunrise ensuring your body has a healthy cortisol awakening response. This is why so many people notice an increase in fatigue during the winter months - a lack of sunlight exposure.As the day progresses into night, you're going to want to decrease your body's exposure to blue light. Blue light is the wavelength that signals to your body that it's daytime. It's this wavelength that suppresses melatonin production. Remember, you need your body to produce melatonin in order to easily fall asleep.In the evening, ensure your electronic devices (cell phone, computer, television, etc.) have their blue light filter enabled. This blocks the blue light frequency from screens which ensures your body is still able to produce melatonin before bed. There are apps like f.lux that you can install on your devices to ensure blue light is blocked when the sun starts to set. Most cell phones come equipped with blue-light blockers in their operating system.Devices aside, as you approach bedtime, you are going to want to decrease your body's exposure to all light sources. Your skin is the largest organ in your body. And it is full of light receptors. Even if your eyes are not exposed to light, your skin will be. Dim all your lights two hours before bed. And be absolutely certain that your body is not being exposed to any sources of blue light.Make your bedroom as dark as a cave. It should be so dark that you struggle to see your hand in front of your face. Blackout blinds are a must (especially in the summer months). Ensuring your bedroom is this dark will allow your body to produce enough melatonin to keep you asleep all night long. Restful sleep is absolutely essential for anyone working towards overcoming fatigue.One last trick that can improve your sleep is to purchase (and use) orange-lensed glasses in the evening. These glasses block the blue wavelength from entering your eyes. Doing this will help increase your body's melatonin production. Resulting in a more restful sleep.Ok, now you know just how important the right type of light exposure is in overcoming fatigue. Do not underestimate the importance of this. It is so important that I include it in my eBook - seven small steps you can take to overcome fatigue today.Now it's time for me to hear from you!How has changing your lighting changed your fatigue?Want to know more than your doctor about how to overcome fatigue and increase your body's energy reserves?

How to power LED lights without using an outlet?Yes, you can use a battery. Details would depend on the number of LEDs, their specifications, and how long you expect the battery to last. repeat, need more details. There are many ways to hook them up depending on the battery size, and LED specs. In general, you need a resistor of the right value, in series with each LED or set of LEDs in series to set the current. .2.

Will leaving the 12V socket into the cigarette lighter socket drain battery? even if led lights are off?If the automobile is off, and the light on the charger cable is off, it surely does now not drain the battery at all. There are some cars where the accessory plug is are living even with the vehicle off, but if the sunshine is going off while you turn off the vehicle, it's not on, and if it is not on, it cannot drain the battery by any means6. Why do those small LED lights break so easy and what can you do to fix them?The base of the LED lights contains an electronic circuit to convert the AC voltage to the proper DC voltage to run the LED lamps. These circuits are called an "electronic ballast." These bulbs were not designed to be shock-proof, so there is probably a broken circuit connection in the base, or in the wires leading up to the LED lamp, itself. It is not cost-effective to try and repair them, but they *are* probably repairable by someone who knows how. (I would personally try to fix one of mine, if they were to break.) .7. Is it possible to change the color of the led lights that backlight the keys on the razer lycosa keyboard?You probably could, but would not be worth the trouble. The colour cannot be changed without replacing them. What colour did you want? =) The term "non-adjustable LED's" I think refers to the colour and brightness not being adjustable. Keyboards these days have SMD LED's (surface-mount) that are tiny, and require you to posess surface-mount soldering experience! I do not think even an electronics engineer would want to waste his time replacing all the LED's. Sorry.8. Where can I find individual LED lights?This Site Might Help You.

Do people use LED Lights? cellphones instd of wired phones?About 19 percent of households in the country had access to electricity. More households in urban areas, 49.3 percent had access to electricity than those households in rural areas, 3.2 percent. Among the provinces, Lusaka recorded the largest proportion of households with access to electricity (51.4 percent), followed by Copperbelt (43.9 percent), Southern (13.5 percent), and Central (11.9 percent). The province with the lowest proportion of households with access to electricity was Western Province (3.5 percent) A modern house in rural Zambia has no electricity. Instead it uses paraffin and candles for lights, a car battery to power a record player and small batteries to run a radio/cassette player. It is perfectly possible to manage without electricity.

Save Electricity Bill by Switching to LED Lights
Without any doubt, lights are the important things for a human to survive in the world. Are you worried about the electricity bill? If yes, then there is the smart solution which reduces the usage of electricity thereby consuming less power. In the past decade, the popularity and the usage of LED lights become high. This is not only used for lighting but also used to decorate the homes, office space and gardens. LED light housing is the best option to decorate the pace beautifully. In this post, you may find the reasons why you should go with LED lights.Energy efficientWhen we consider the normal bulbs it consumes only 50 to 60% electricity for lighting and the remaining is converted into energy. Where in case of Light Emitting Diode it uses more than 80% electricity for lighting remaining as energy. It is common that the brightness of the light will become dull after few months. But it is not true in term of LED lights.Conventional forms of lights produce heat and release Ultra Violet radiations. LED bulbs are environment-friendly and the UV radiation produced by the light is almost equal to zero. LED high bay Housing helpful to decorate your house. There are no filaments used in LED lights and it can last up to ten times longer than standard lights.The color options available in LED lights are more compared to traditional lights. The government also highly recommends LED lights for the efficient use of power. You may find most of the Street lights are LED.Most of the people have the common question that is the LED lights fix for all types of fixtures? The LED lights are designed to fit into various types of fixtures. So you don't want to worry about the fixtures. Nowadays lights are available in various shapes and designs this enables the customer to decorate their home and brighten their homes.Applications areasLED lights not only recommended for residential areas this also recommended to use in the commercial places and public places. This lights also used in car lights. You can protect the light from various climate factors like rain, winter with the help of LED Streetlight housing service offered by the best LED housing manufacturers in India. The compact size and faster switching are the additional advantages of LED lights·RELATED QUESTIONI didn't get Google Glass Explorer Edition.

Are LED Lights Eco-Friendly?
Light-emitting diodes are an eco-friendly lighting choice. LEDs are an energy-efficient alternative to traditional incandescent light bulbs, which waste 90 percent of the energy they consume on heat. Other energy-efficient lighting options include halogen incandescent bulbs and compact fluorescent lamps. All incandescent and fluorescent lights produce light that flows in all directions, wasting light as well as heat.LEDs are a rapidly advancing technology that uses energy more efficiently and can save energy in indirect ways, such as with air-conditioning costs (see References 1). LEDs use small, powerful sources of light that illuminate when electrons move through semiconductor materials. They shine in only one direction, produce a small fraction of the heat of fluorescent and incandescent lights, and lasting longer than other types of lighting.Energy Star, a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, labels LED lights that meet its energy-efficiency guidelines. Although LED lighting design creates efficiencies, poorly designed LED lights do not meet the potential of the technology. Energy Star guidelines require that LEDs consume at least 75 percent less energy than incandescent bulbs and last 15 times longer. In addition, the bulb must turn on instantly.LED low energy-usage saves money in utility bills. As of 2011, an Energy Star-qualified LED bulb has an average operating cost of $1 per year. That compares to annual costs of $1.20 for an Energy Star-qualified compact fluorescent bulb, $3.50 for a halogen incandescent bulb and $4.80 for a traditional incandescent bulb. In addition, an Energy Star-qualified LED bulb's longer life -- ranging from a minimum of 15 times longer than a traditional incandescent bulb to a maximum of 25 times longer -- means there is much lower turnover of bulbs in your house. (See References 2 and 3) Technological advances with LEDs raise hopes for significantly reducing electricity usage in the United States. LED lighting could cut the electricity demand in the country by 1/3, according to the U.S. Department of Energy. The estimated savings from that adoption would total $265 billion, including preventing the construction of 40 new power plants.
Can Anybody Explain to Me How I Could Instal Interior Underglow(led Lights) to My Car W/o the Cigare
Just run wires straight from the battery for positive and negative1. doesn't ohm's law applied to every thing? [closed]Ohm's law specifically deals with the relationship between direct voltage, current and linear resistance in the form V = IR. For AC circuits it can be generalised to V =IZ where Z is a complex impedance.Transformers convert an alternating primary current into an alternating magnetic field in the core which is then converted back to an alternating voltage in the secondary coil - This effect was demonstrated by Michael Faraday. (Google Faraday, transformer) He showed that the input and output voltages where connected by the turns ratio. For a 100% efficient transformer we get:We must also apply the conservation of energy rule - you can not get more out than you put in. Given that there will always be a loss of energy (heat, noise etc.) the power output will always be less than the power input. always greater Iin * Vin > Iout * Vout (Power in is always greater than power out)If a load is connected to the secondary coil a current will flow. The transformer will react by increasing the primary current in line with the transformer turns ratio in order to maintain the power in to power out relationship.A filament bulb works by heating the filament to a high temperature. Most of the energy used is radiated as heat rather than light, making this type of bulb inefficient. The colour of the light is determined by temperature. (Google black body radiation, Stefan-Boltzmann law).'Energy saver' bulbs use a gas discharge lamp and phosphor coatings to produce light. (Google - Electric discharge in gases) The current passing through the reduced pressure gas excites electrons directly which then jump from one energy band to another before decaying and emitting a photon. (Google - Planck-Einstein relationship) This means that they generate light energy directly without the need to generate lots of heat energy. This makes them more energy efficient that filament bulbs for the same power input. Hence the term 'energy saver.'LED lights (Google band gap, LED) use a similar principle (electrons jumping from one level to another) through a PN junction in a semiconductor.This is more efficient than gas discharge lamps giving LED lighting more lumens (light output) per watt.2. Sleep Peacefully at Night: How CCTV Keeps Businesses Safe in the DarkNight vision cameras were once the standard for the military, scary movies, ghost hunting, and those energetic wildlife enthusiasts. Nowadays, nearly anyone can make use of the technology, especially when protecting business properties. Night vision technology is instrumental when it comes to business security. Several burglaries and attempted break-ins occur at night, and there are many things you can do to improve your business's nighttime security. For example, installing motion-sensitive lighting and night vision CCTV cameras are the most feasible solutions to help you sleep peacefully at night. CCTV keeps businesses safe. Several surveillance cameras are motion-sensitive and can send alerts when movement is detected. You will instantly know if someone is trying to access your facility without your permission. Yet, typical cameras can not see in the dark, so they can not always pick up motion and send you the essential information you need. This is where the night vision comes in. So, how does it work? Infrared, or IR, is the most common type of night vision popular in outdoor security cameras. This kind of technology is brilliant; it can flood an area with light invisible to humans, but the camera's lens has no trouble picking it up. A possible intruder would see complete darkness while the camera would film in near-perfect clarity using the IR light produced. Humans cannot see IR light because it has a longer wavelength and frequency than normal light that's visible to the human eye. Red is the color with the longest wavelengths visible to humans, and infrared means 'below red'. On most infrared cameras, you will see a unique configuration of bulbs being used. Higher power infrared LED lights are positioned around the outside of the camera lens. IR is used for several different filming purposes and is typically used for wildlife filmmaking. This is because the invisible IR light does not bother the animals as they cannot see it. This makes for a very secretive, nocturnal filming opportunity. Another type of night vision filming technology exists. It's not something commonly used in homes, businesses, or even professional security cameras. Image intensification tubes are used in night vision goggles to collect and significantly intensify all available light, including infrared light. This allows the wearer of the goggles to see in low-light situations or even in total darkness. When an area appears to be completely pitch black, it never truly is. There usually is a source of light, even if the human eye finds it difficult to spot. The light entering the goggles is converted into a green tint, making people's eyes shine brightly in the image created, as human eyes are most susceptible to green light. Night vision goggles that employ this technology are most likely used in military and law enforcement operations. Night vision is instrumental in security cameras since it allows the camera to detect motion more adequately, thus picking up movements by an intruder with ease and alerting you immediately. Although, there can be occasions where you (or the police) cannot get to the location in time, and the intruder makes a getaway. If this happens, your night vision cameras become even more valuable. The clarity of the footage that they can record with IR light and night vision technology means that perps can be more easily identified and arrested. The footage then becomes very useful as evidence. In contrast, a standard surveillance camera would pick up a blurry image in poor lighting or absolutely nothing at all in the pitch dark. Most night vision CCTV cameras also come with extra features and functions to further enhance the footage's quality and clarity. These include: Capture Faces, Number Plates, Etc. With This Technology With this new technology, you can capture faces, license plates, and many other details to provide to the authorities. A lot of activity takes place under cover of darkness, and night vision cameras can help you keep a sharp eye on what is going on. This is very useful in legal cases, investigative matters, or just to provide everyday proof of suspicion.3. Why paintball marker is better?1. They are all under 2 lbs. You would never be able to tell the difference, though. 2. Egos are technically more air efficient but efficiency among high ends nowadays is such a dead topic because they are ALL more efficient than anyone could possibly care. 3. Better settings? Like ease of settings? Because they all have the same tourney modes. Egos are probably easier because they have an LCD screen instead of LED lights. 4. They are all easy to maintain but Egos are a little faster in the maintenance dept (less o-rings to lube). 5. I prefer spool valve guns over poppits, so i like the DM's more. Never shot an NT but i can not imagine it feeling too much different than a DM.
How to Add Turn Signals and Wire Them Up
How to Add Turn Signals and Wire Them Up Want to add turn signals to your hotrod? You should! It's not that hard... 3. Make your own switch system. (It's easy!) Factory switchMost of you will have a hotrod that uses a steering column that has a turn signal switch built in. What you need to do is find the wiring diagram for the vehicle the column came from. Just find it on the internet. It will show you which wire should go where... Some of you will have a hotrod that does not have a factory switch in the column. The easiest way to add on turn signals without a factory switch is to use an aftermarket unit like these universal types: You can get them at places like Napa or here: However, some people do not like the look of it so they want to hide it. It's easy to put that unit under your seat, by the shifter, etc. Still others would like to run their turn signals with a simple toggle switch on the dash. There are two ways to wire it in... -Wiring in turn signals that have their own seperate rear bulbs. -Wiring in turn signals that share the rear bulbs with the brake and tail lights. Let's start with the first... What you will need is a toggle switch and a flasher unit. For the toggle switch you will need a SPDT (Single Pole Dual Throw) toggle switch. They look something like this: They work something like this: You can get them at places like Napa or here: Next you need a 2 pin flasher unit. They look like this: You can get them at places like Napa or here: NOTE: If you want to run LED lights or bulbs, you will have to run an electronic flasher unit. You can get them at places like Napa or here: Now, wire them in like this: Ok, now to wire in turn signals that share the rear bulbs with the brake and tail lights, you have to get a little creative... What you have to do is make the brake light wires and the turn signal wires combine in a way that the turn signal wires can override the brake signal. There are complicated ways to wire in multiple relays to do it, and aftermarket units that will do this but there is an easier way... A quick and cheap way that works just as good is a tail light wiring converter for trailers. They will combine the brake wiring and the turn signal wiring so they will work. You can get them at places like Napa or here: Some have the tail light wire running through them (4 wire into 3 wire), and some do not (3 wire into 2 wire). It does not make any difference, as the tail light wiring is not affected. All you are worried about is the brake and turn signal wires. Note: Do not try to run them with LED's. The converters are not made to run the extra voltage. Just stay with regular bulbs and it will work great. Now wire it in like this. (This version uses a 4 wire into 3 wire converter. For a 3 wire into 2 wire converter, just take the tail light wire past it.) No problem, you just need another toggle switch and flasher unit. The toggle switch is different than the other though... For the toggle switch you will need a DPST (Dual Pole Single Throw) toggle switch. They look something like this: They work something like this: You can get them at places like Napa or here: Now you need another 2 pin flasher unit. Now wire them in like this: Return from Turn Signals to Hot Rod Wiring Return from Turn Signals to How-To-Build-Hotrods1. what household items contain led lights?Desk top computer front panel and its enthernet card beside the plug input ; DVD player; Game device : remote control has IR LED in its front ; USB drive ; monitor front panel ; printer panel ; LED bulb ; LED tube ; garden solar light ......so many2. No video imput when computer turns on?Your computer is not running POST. As it's a fresh build, you need to double-check the power connections (there should be TWO of them) from your power supply to your motherboard. If all the connections look good, the most likely problem is a dead power supply. Even if the power supply appears to turn on, it can still be dead. In other words, LED lights lit and fans spinning does not mean that your power supply is good.3. What's the difference between fluorescent & led lights for aquariums?Theres lots of difference. The main one would be that LED last longer, penetrate deeper, and uses far less energy. Beyond that the type of lighting, colour, and effects on fish and plants depends entirely the type of LEd and bulb used. Theres lots of variations between different fluorescent or LED lights. I have some LED's on one tank that are a slightly daylight yellow colour. They grow my plants well. However I have another equal sized stip of LED that wouldnt grow anything if I tried. I use them as moonlights. So in the end it just depends on what the individual person wants..
