    hi guys i am sory i havent post for a wild but i have bean buisy, i have bean working on a projet the is realy shalenging, as you all know led lights are not sheap.well there is a sheaper way,making one using superbrite
    (CREE RX-E P4) led's i am using 12 led, i am runing them at 900ma the max is 1000ma because i dont want to burn them, they last 100,000 hours i dont have To shange them for around 10 years. O and from where i am standing they look briter them MH, they are super brite and is olbust blinding looking at them and i am not joking, and they are runing at about 1w each but with other conponents when i fininsh is about 20 to 30 watt of power comsumtion. now i am not finish here is a look at were i am i think total cost for tha projet is $100.00 prise gos up when you use more leds and drivers ...but you can make your own as i did...
    SORRY ABOUT MY ENGLISH I KNOW IS NOT THE BEST... IM001156.JPG IM001155.JPG IM001157.JPG IM001158.JPG IM001159.JPG
    i am just i n the test face of the projet so it looks ruf but i will make it realy nice is going to look like it a bout it from a store, and i am going to be ading more leds as time passes. i am making 4 pots with reflectors and 3led's per pot wish i will be ading more leds to the pots in the near future...

    Here are the part i use for this projet
    parts
    1-pc power suply
    12-LED's super brite from cree rx-e p4 you can get them on ebay or shina
    4-heat sink's, but you can use one big one i just use this because i had them and you can order them on ebay
    3- 12v fan's from a pc
    4-1.0 ohm 1w resisters
    4-LM317 trasistors
    the resisters and the transistor is to make a driver but you can buy them on line for $15-20 and they can run up to 6 high power led is your shoice

    Awesome idea using the heat sinks and thermal paste to draw heat from the lights. Mount a small pc fan on top of those heat sinks to draw air across them, and it might would help even more. Great idea either way! Edit: At a second glance I see that you do have fans listed as materials used, sounds like you've thought this through sir. K+ for ingenuity!

    Keep us updated. Do you know what spectrum they are? I applaud the effort.

    Pretty cool. I would only be concerned about getting a 10-14k spectrum. It would be cool to test them over different tanks / corals to compare growth.

    cool, I think those are gonna work great. They look extremely bright and should penetrate well. What size tank will you be putting these over? How many?

    Our LFS is making us some LED lights for a 6 Gallon Nano. We are picking them up Friday.
    I will post pics of them.

    Looks like a fun project Freyre
