CREE led suplement

[ongmat]

hi all, just finish a led bar mount in my DIY hood light. every thing work out good but still need 1 more to blue up my 2-250w w/ ushio 14k which i 've known, just wanna try it out fisrt.
2 strips each has 6 CREE XR-E leds on one bar, power by 24v @ 700mA...total cost is $165 from ledsuply.com. the next one i'll use 1000mA drivers.
they really blue up my tank good...i like a new look of my tank now:bigsmile:

any comments r welcom...

Looks good, You will love the led's. Just remember the led's dont do good with saltwater hitting them, and the xre series @1amp are alittle brighter but build alot more heat. Good emitters for running 1-1.5 amps are the xpg series.

yep, and i got 4x80mm computer fans @ both ends to cool'em down...measure temp after hours @ the bar is 145F and 165F w/mh on....the XP-G does not come in blue which i want and confirm w/ led suply rep...but thanks for ur input....it's always good to know more than less,,,,right?

For blue they are not xpg's the they are xpe's, not the same lumens output. They have alittle more output then the xre's but with less foward voltage and heat. Watch the temps, the you can read 145 on the bar the back of the emitter is probally close to 200. Don't forget to post some pics when you get the light on your tank.

where can u find specs to compare between XR-E/ XP-E output? that might help me to make another one.....

cutter led has links to all the cree data sheets. If there is anything you are haveing a issue finding let me know, I have done way to much led research.

my volt/temp meter needs battery....more accurate reading after changed....110F right at a back of the star board...wheeeew:whew:...feel alot better now.
here r pics of the tank @ day and night (only 1 bar on)
