It's been a lonnnnnng day and that was just what I needed! :S2:

I'm sitting here looking at charts and jotting down wavelengths. I have to let the manufacturer know tomorrow how I'd like him to make the two lights for me.

I'll try getting the 90W UFO light with the mixture of the blues using the absorbtion peaks you've shown me in those charts. Let's see how the plants like it with just blues for veg.

For the flowering light I'm going to load up on the 660's per your advice. Though, with me using the 1W LED's as opposed to the 15W ones that you use is that ratio still alright? Or, should I use more red and less blue since they are weaker lights? More like an 8:1 ratio because of their weakness? (they bow down and cry in the presence of your lights!)

Your thoughts?
ledtime Reviewed by ledtime on . Calling out to Weezard for LED advice My friend, I've read your stuff here and at Steve F.'s site. I want to build a dedicated flowering lamp using Ledengin 15 watters. (4 reds, 1 blue, and possibly 1 warm white; LM 317's so I can tweak the ratios.) Essentially, a copy of your 4+1 cake pan lamp but built on a 4 x 18" finned heatsink so I can see what's going on under it.) If I were to post my picks for power supply, resistor ratings / values, etc., would you critique and perhaps offer some guidance? I have already purchased Rating: 5
