So, we just finished testing the PAR on my new LED that a friend of mine is building for me tonight. We're using 26 total emitters of 10w LEDs (12 x 10000k; 8 x 455nm Blues; 3 x 20000k; 3 x 6500k) for 260w max over a 5'8' x 2' x 2' 165g full reef tank.

My bad. Got lost in all those numbers before. I like the low profile look. Are the LEDs recessed or just mounted on the heat sink surface?

Also, who's the manufacturer of the 10W LEDs?

They are screwed onto the heat sink surface. My friend is going to add a 2" aluminum "shield" around the entire unit to block off the light so someone looking at the tank or walking by won't see the LEDs.

(more numbers to get lost in) Each emitter has a 100 degree spread which is perfect. 13 emitters per 5'8" heatsink and it's 12" wide, 2" tall. It's literally only 3.5" from the water surface, with good shimmer, full spread and no "spot lighting" or "disco ball effect". The two fans blow air up on the right side but most of the cooling is my conduction/convection. With all the lights on, there were still sections of the heatsinks that were cool to the touch and at most it was barely warm in parts. My friend will be adding pieces of aluminum on the open ends of the rectangular tubes which will make the fans more effective.

I can literally pick up the lighting unit with one or two fingers.

Just running the blues at half power and I've noticed one advantage of these LEDs is that even though none of the white lights have been on for at least 4.5 hours, many of my corals are still fully open. They usually closed up under the old moonlights within an hour or two of the MH going off. I'm liking this development

Hi Anthony

The lights look great. You are definitely on the right track.

What a win win.

Better Par at half the juice.

I look forward to coming over for a real good look.

It's looking really nice. What manufacturer makes those 10w leds?

Sounds like a kick arse unit!! I would love to have a par meter to test out mine to.
