That's very surprising. I am skeptical but I hope those readings are correct.
All I Can Say Is Damn These Leds Rock

No spotlighting thats the reason I used so many leds (if you point the leds at a flat surface less than 8 inches away you will start to see spots)
I originally used 8 leds in series per buck puck because the BP is 32v max and the leds at max power are 3.7X8=29.6 but the BP says up to 6 leds so I had to cut 2 leds of each string and add some buck pucks. There are others using 8 per BP I just didnt want to take a chance in case I had to run them at full power
Regal just looking at it I knew it was way brighter than my 150mh fixture with less than 3 month old bulbs so I was happy no matter what i figured the it would be like a 250mh though I never had a 250 my 150 has been plenty of light and I never had any issues with my sps and my existing light fixture just wanted to cut down on energy use and heat.
My claim of "over 400 mh par readings " are based on what melevsreef posted with his same brand par meter and a 400 watt mh with new radium bulb.
Looks really good there! Yeah I wouldn't recommend more that 6 LEDs per buckpuck unless you want some dead pucks. I'm building a LED fixture right now as well your PAR numbers are similiar to some PAR numbers people have been posting over at nano-reef as well. I think these LEDs are showing a lot of promise and as the technology advances they will just get cheaper and cheaper.

Hey that looks nice!. Can you let me know where you ordered your leds and etc. I want to make one for my 10 gallon tank.
Thanks!

I can attest to those readings. Used Apgoee MQ-200 to measure that was three months old. Readings were off the roof.
ouch:splitspin
Yeah but the LEDs last 13 years under normal use and draw far less power than a MH fixture. In the long run you save money.
I havnt set it up on my display tank yet (just temporary for testing) I did however set one up on my pico tank and the zoos started bleaching a little bit because i had the lights at 1/2 power and that was too much for an 8 inch tank with zoos so I just turned the power down a little more and everything is fine.
On the big fixture for the display tank i can control the intensity of blue lights and white lights separately and the blues can come on by themselves first then the whites. I will set the power when everything is done and forget it . I will be able to set more or less power in any given section so sps can get full power after acclimation to light were lps will get less

Ok its 95% done now I see why they are so expensive to have someone build these light fixtures the total cost of material was around $1800 for a 6 foot fixture and a lot of labor .
I can make an aluminum or stainless housing to cover everything and might consider it in the future but for now its staying like this being that its in a fish/laundry room and looks dont matter, I'm just going to make the wires neater .
This is the test run and wanted to take some quick pics the light output is crazy even though I dont have the optics for all of the leds(back ordered)

Emmanuel, for the intensity are you controlling them by a dimmer ? Also how are you dialing down the power ? you said on the pico tank you had them 1/2 power then then dropped it. Is it by the buck puck your using or something else ? Very nice set up thought looks like alot of work. Great job !!
Is this with white and blue on at 100%? Can you take a actinic only picture please? How many led do you think I will need for 24'' cube?
that shot was with blues on all the way and whites about 50% the white ballance wasnt set on the camera perfect but the lights at 100% look like a 10k and just blues gives a crazy actinic look for a 24 6 blues and 6 whites should be way more than enough its better to use a little more light than a little less.With more you can always turn it down , with less you would have to do it all over .I am assuming you meant a 24 gallon like aquapod I am using 36 bulbs total for a 24x18 inches half blue half white

Dood, this looks amazing. You need to put a DIY LED together! I want to make one, but I have no idea where to start! :splitspin

Manny - Here's a few questions, after reading soundwave's thread.
1. How many leds would I need for 36"x18" (58gal) tank? I would imagine I need more light near the center, and less in the corners
2. What controller did you use to dim?
3. The way you have set it up - if one light goes out, do all them go out as well?
4. Did you use epoxy to glue the leds to the heatsink? I saw a holder/mounting boards that seemed pretty cool, and it would be easy to replace.
