Calling out to Weezard for LED advice

[headshake]

Haven't been followiing real close. Long division cornfuses me. But isn't 430nm in the ballpark where they start talking about radiometric power and not visible light? Or is this just a kickass blue that's still cranking out that much visible light?

Looks intriguing, either way. Good find (hopefully!) :thumbsup:

430nm is in the violet range, just before blue. (violet 380-435nm; blue 435-500nm; uva (longwave) 320-400nm). so i guess the violet and the uva overlap a bit, hence the violet color of a blacklight?

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
