Hey Weezard!

I've been lurking this thread for some time now with interest. That's a nice setup you have been building there. As the 5watt, 15 watt, and future generations of LED packages become available more cheaply using them will make even more sense then now, but someone's got to pioneer the method, eh?

They make axial fans that are wisper quiet yet blow like a hurricane, I've replaced them in CAT scanners, but they ain't cheap.

I love the tunable colors, by the way.

I went to a demonstration of LED surgical lights as part of my job. These were CREE and LEDngn LEDS in large arrays. One of the companies made a controller that allowed you to control the "color temperature" of the output. There's got to be a "controller" out there to allow you to drive the LED arrays by your computer.

Anyways good work and carry on... :thumbsup:

MerryPrankstr Reviewed by MerryPrankstr 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
