That is absolutely, 100% false. 6 watts of LED does NOT come even close to producing the amount of light from 100 watts of HID. Yes, 6 watts of LED produces next to no heat, but that's because it produces next to no light. If you had a 6 watt HID it wouldn't make any heat either, and it would put out a hell of alot more light.

You will not grow any amount of smokeable marijuana using only 6 watts, I guarantee it.
BigBlock Reviewed by BigBlock on . About those LED lights I was reading that in order to equal one decent HID light, you need a panel of like 52 LED grow bars. One LED grow bar goes for $150, so that's $7800 vs like $300 for the HID. You do get greater bulb life, but 52 led bars, with three light clusters per bar, is going to take up quite a lot of space, so there's absolutely no real advantage. So don't waste your money on LEDs.
