Diy led

[cabezon2469]

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

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

So the party is tomorrow?

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

 

[killerbee181]

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

just FYI, I have used the SEMI leds like you guys are using and always keep spares around because they tend to just burn up. Looks very good btw

 

[cabezon2469]

$1.27? man You found a great price.

some update...

Wow nice build. You are probably going to have to dim those waaaay down though. I did 48 3 watt cree led on my 90 and can't run over about 30% without bleaching/ irritating most of my corals( they were used to 260 watts cfl). Awesome set up, just be careful.

 

[GUILLO1]

Jae, I would put some of the blue LEDs to. I would do like 3 blues to every white.

It's really looking good.

I just came back from Jae's house. Wow. So bright and the perfect color. Just a hint of blue not the normal white ,white. We may not need any actinic supplementation.I just cleaned my heat sinks and will be gluing them this weekend. I will be running ether 88 or 166 leds on my tank.

 

[killerbee181]

wow that looks great! Really interested in seeing how it will look over the tank and what kind of colors you will get out of them.
Do they have a ballast that powerful that is dimmable? Or are they ridiculously priced?

 

[forddna]

joseph, what size is your tank?

 

[josephv]

72 by 18 by 24 inches

 

[forddna]

Cool, thanks.

Nice work- I just bought the 57g (36" long) from Chris and I'm thinking of doing something like this for the tank... Whats a good place to buy the parts, this would be my first project...
