Where can I buy 1000 Watt LED Grow Lights?
I have been asked many times in the last couple of months about 1000 Watt LED Grow lights . . . do they exist, are they necessary, where can I buy them etc.
The conclusion I have come to is that many are still confused about the power of LED grow lights and how they compare watt for watt for standard HPS and MH grow lights? I will try to clear up some common questions about LED grow lights to help you determine if they are the right choice for you.
Most importantly, you must realize that you cannot compare LED Grow Lights to HPS or MH on a watt-per-watt basis. For example, a 1000 Watt HPS light must not be compared head to head against a 1000 watt LED grow light because the LED light would blow it out of the water every time. To keep things fair (well, sort of) you must compare the 1000 Watt HPS to a 600 Watt LED grow light and here is why. It all comes down to the yield a given light/plant combination will produce. In this case, a much lower-powered LED grow light will produce the same or better yield than its HID counterpart.
Why You Probably Don't Need 1000 Watt LED grow lights
The reason lies in the relative efficiency of the light waves produced by each kind of light. An HPS grow light produces light in the full spectrum with a bit of an emphasis on yellow/orange range. In addition it emits a tremendous amount of heat - the resulting efficiency is on the order of about 15% which means 85% of the light is wasted because it is un-usable for photosynthesis or is lost as heat.
In contrast, the best LED grow lights will emit light at very specific wavelengths in red, blue, and red-orange bands. Nearly all of the light produced is light that is used directly in some stage of photosynthesis and plant growth. In addition, there is very little heat produced and, therefore, wasted by an LED grow light so the overall efficiency exceeds 90%. This means that a 600 watt LED grow light can match or outperform a 1000 Watt HPS in terms of yield - eliminating the need for expensive ballasts, heat removal systems, and replacement bulbs, all while saving you money on electricity.
