Wow Old Mac...that is one stout lady you have there! :thumbsup:

The dual blue light should be interesting. I'm just concerned with the output of the flowering light. I would be MUCH more comfortable with a true high powered LED light, but I don't have the tools to really do it right. I would make DH feel good with how many LEDs I could burn up...and there aren't that many to go around!

So weez, you think three is a good limit for buckets in that size space? I was thinking four would be a bit much if they get bushy....
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
