EBOLII, lot of good info on power issues over on http://www.reefcentral.com/forums/index.php?showforum=25
They have a very active forum, especially in the LED lighting arena.

This is great.
I have (cough) several of the PFO Solaris units that will now no longer be serviced by PFO.
I'm wondering if I could basically rebuild them using the nice looking case. I recently had someone put a PAR meter on one of my units and I wasn't pulling the kind of PAR shown in this thread.

So if I have understood right ( and please correct me if I'm wrong I'm still learning LED stuff) If I use lenses the pPAR goes up but I lose some coverage, so for a tank that will be 30x30x30 I would need to use more rows oF LED's to get the even coverage as shown without, but I would get the PAR numbers up to around a 400w halide that would be needed for such a deep tank?
(sorry for the long question)

Great write-up, The best one I have seen on this subject to date!
A follow up question to Dtech, when using optics would I want to mount the LED's closer together (>2") since I am now focusing the beam?
Also I do not believe in your DIY it says you spaced out your LED's 2" but someone commented on it, therefore can I clarify it is in fact 2" and if so is that a measurement from Actual LED to LED or the space between each edge of star mount? ( I assume it is LED to LED)
Cheers and thanks again for a great step by step DIY on LED's

great write up man i love it.
I would love to do something like this for my nano and was wondering if you could tell me if this light would work, dont mean to hijack your thread.

i am currently running a similiar set up for my moon light's which contain a driver and you can program it off your pc. i have a string with 16pod's on it each module if you will contain 3led's a red,blue,green with those three colors you can actually change the mood from like 3.1million different colors some of you might have seen my diy mh setup with color changing moonlight's the led moon light's were all programmed by a friend at work for me who gave me the set up"i work for a sign shop UNLIMITED SUPPLY OF LEDS" lol!!!anyways he was showing me the dmx programmer you can buy online which allows you to have different presets for color changing temp changing and such also dimmable via a remote on the couch for crying out loud....everyone is defenitly onto something with this whole led thing but with the 3 colors red,green,blue you can dial in the temp rating from 3500k to probally well above 20k it's amazing as i played with mine turn all 3 on at one time and it's a crisp white to the eye looks like 14k who would of thought???????turn on red and green get gold looks like a full moon it's really wierd and truly amazing im gonna have to get the full info on my set up and will share with everyone interested...
Great job sound wave. Just one question can you explain your LED selection better. Are they the Cree x-re q5? I know you can get the q5's to produce 228lumens at 1 amp. Thats extremely bright for a single LED. Also can you make a full wiring diagram to go with? If you want cheaper LED plus free shipping go to dealextreme.com.

EBOLII: The math goes either way, all you need to do is add 6 LEDs to one buckpuck. As long as your power supply can handle the draw of the LEDs, amperage wise, you can make a fixture of any size with LEDs in multiples of 6.
dtech: I'm gonna say yes.
skeet103: I didn't space the LEDs exactly at 2". I just put them where they were evenly spaced and haven't measured. The optics are the same size, generally, as the star plate the LEDs are mounted to. You could but them all together as close as you want and still add optics. If you space them any more than 2", you MAY get a spotlighting effect. I don't know for sure since I haven't tried it.
wsukid12: That light MIGHT work but it's only using 1 watt LEDs. They are far dimmer than the true Cree LEDs. The 1 watt models run at 350mA and are very weak in comparison.
jimnrose: Thank you for pointing that out. I hope since this is now available, nobody gives their money to a certain company that decided to get a blanket patent on LED fixtures for "marine growth". Since I'm not selling a fixture but explaining how to do it, I'm in the clear. Also, this will save everyone money in bulb changes and electrical bills.
MOFelix25: I used the XR-E Q4 LEDs. I trust LEDsupply far more than dealextreme. If you have any questions, the staff at LEDsupply are super helpful and they speak English as their primary language. I COULD HAVE ordered from DealExtreme but I've had bad experiences from them. If you don't mind waiting a month for your LEDs to show up just to save a few bucks and have absolutely no customer service, go for it. As far as a wiring diagram, I'm sure I can muster something up. Give me some time, though. Busy guy right now.
