And about heat, think about 6 watts of LEDs equaling at least 100 watts of HID. 6 watts will produce almost no heat, plain and simple. The LED is the superior light, as long as the proper technology is used to assure that it effectively promotes plant growth. And Solaroasis appears to have achieved this.
Crispyfried Reviewed by Crispyfried 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.
