Where did you get the leds from?

GlassReef 12/23/2010 02:49 PM

Looking good, Jae. Will the aluminum frame serve as the heat sink? How many of the frames will you need for your tank?

I think each 3W LED only use 2.1W electric.

I think Jae can't sit still , once the parts come in , there is no holding him back .

CMcNeil 12/23/2010 09:00 PM

do you think the aluminum beams you are using will be sufficient for cooling the LED's?there isnt alot of surface area in those beams so im wondering what your plans are.

Chris , Jae did some test pieces , and they didn't get what you would even call warm . After running for over an hour , you could hardly notice any heat . The channel had a slight warm feel , and that was w/o a fan .

flworkd 12/23/2010 09:46 PM

first heat test was used 3W 350mA almost no heat on C channel heat sink
now I'm using 3W 700mA, yes there is some heat but not hot. any air moving will help to lower Temp

CMcNeil 12/23/2010 10:53 PM

That's awesome,nice build BTW.how many bulbs total are
You going to run?

you are still looking at almost a thousand watts of MH equivalent.

So the party is tomorrow?

forddna 12/24/2010 12:01 AM

What is your estimated expenses for each of you? Just curious.

killerbee181 12/24/2010 02:01 AM

Wow that looks great! Are your ballast dimmable? You using white and blue LED's? If so what ration are you using?

Terry , The color temp of each LED is 18000-20000K , so we may not need any blur LEDs . We may add some blue LEDs later , just for Dusk-Dawn viewing
