Got into the JBJ Led set-up because of heat issues with the halide. Running a combination of Luxeon Rebels and Cree XRE. The Cree seem to be a bit more power hungry so I switched to 23 instead of 24 leds for the time being just can't drive them all. All mounted and tested . Mounted on an 8.5x11 inch heat sink from heatsinksusa. The drivers are all in ones 55 bucks a pop and they will drive 11-12 led, not 14 like they are rated at 700ma.

oOoOoOoOo ::

very nice! are running fans on the rear of the heatsink? also any dimmers
I wanna see that lit up, whts the color temp look like

The Luxeon royal blues are on a dimmer, I'll be using the stock JBJ fans with a slight modification to the OEM hood to improve airflow since it's a blow threw design which was fine for the halide but not so great for the led set-up. Worse case scenario cut out the top of the hood paint the heat sink black and add a fan. I don't think that will be required. Color temp with 50/50 ratio should fall into the 12-14k range, of course you can turn down the blues if you want more of a 10k look. I'll take some low resolution shots of the arrays lit and post them later.

Very impressive. Can't wait to see the finished product.

Can't see, the Cree are much brighter than the Luxeon!!

OWE MY EYES ::

Nice any pics of it on top of the tank?

 

[jbishop]

Very cool.

No way of doing that at the moment, once I finish up a few details the halide hood comes off and the led hood goes on. I might also pick up a driver for the 1 led in the corner. Kind of bugs me and that corner will be low on light and if needed I could add a few more to the sides since I have extra rebels anyway. One of the guys over at nano-reef.com says it should be close to the 150 watt halide in output but with no heat!

what are you talking about Jeff?

want to make me an LED light?

Wouldn't take much time for a 5.5 gallon. Oh and Evil does custom work also he might build you one!! It would cost you though.

Lets see 6 leds, 3 royal blue 3 Cree XRE, small heat sink, 1 all in one driver, 2 if you want dimming control of the blue It would be sweet

Let me know if anyone is interested in a little project
