Why Do People Prefer LED Lights Over HID Lights? 2019 Updated

The pricing of LED grow lights has also dropped substantially over the last few years, which makes the argument for LED grow lights stronger. Those who have been using HPS lights for years may resist the change to LED grow lights, particularly because of a higher upfront cost. However, LED grow lights are typically cheaper to operate in the long run thanks to reduced power consumption and elimination of regular maintenance.

With HPS grow bulbs, the intensity drops off significantly over time so you will have to replace your HPS bulb regularly to ensure you are getting the most out of your grow light. LED grow lights don't lose intensity like HPS bulbs and are typically just as bright until the very end of their life cycle with a general lifespan of 50,000-100,000 hours.The downside of opting for HPS lightsHPS grow lights generate an incredible amount of heat, requiring additional ventilation and monitoring equipment to ensure a proper grow room temperature is maintained.

HPS lights are less efficient over time than comparable LED lights, not only using much more electricity but also requiring more maintenance over time.HPS grow bulbs significantly diminish in intensity over time and require replacement every 12-18 months.LED grow lights differ in shape and size, presenting options that fit every grow space and circumstance.

Most high-end models are shaped as panels, but there are also models shaped like saucers and bars.Emitters are another aspect that varies across models. The most sophisticated ones feature ten emitter types at different frequencies, whereas lower end models just have two or three.

The chips also play a big part in distinguishing LED light types. The two main approaches are to either feature few but powerful broad spectrum based chips, ranging between 5 and 10 watts or to feature many single LEDs with each one shining at a different frequency.Naturally LED lights also differ in terms of quality build, warranty and support, flexibility, luminosity and of course the spectrum that they cover.

Benefits Of LED Grow Lights Over HID Grow LightsThe old school HID grow lights for plants can get the job done, but they are very inefficient when compared to the state-of-the-art indoor grow lights.LED grow lights last six times as long!Eco-friendly LED grow lighting uses no toxic metals.Energy savings range from 50%-70% over HID lights.

No cooling necessary; no plant burn and decreased risk of fires.LED directional lighting requires no reflectors.Maximum chlorophyll absorption and flower production.

Less frequent watering.

Discretion assured - no thermal footprint.Environment advantagesLED grow lights do not require as much power. They also don't require you to dispose of harmful mercury and they don't need new bulbs to be produced every year.

There is a reason LED technology is often mentioned in the same sentence as alternative sources of power like solar: the are much better for the environment than traditional forms of lighting
