Wanna Try building a LED light
Ok Im pretty handy and building things so.
What would be best here: my tank is 60x24x24 150 gal all LPS so what is the lighting requirements for a lps tank since my current lighting is 2x400's 20K XM's can I get away with 48" light strip? How many BLue's ? How many White's ? Type's of reflector's/optic's? How do you attach the led's to the metal board? is it aluminum Type's of LED's ? Type's of transformer's ? Type's of heat sync's? How many Fan's? Smaller ones or the larger ones. what type of wire's should I use what gauge?

I would go 2 blues for every white.
Cree 3W LED's are the most popular. http://ledsupply.com/creexpg-w139.php They come on an aluminium disk, its about 3/4" diameter. Don't make a single strip, make an array. I would buy dimmable drivers, its just so much easier and they are cheap all things considered. Optics... try some of all and figure out what works best, makes it easier to give a smaller spot more light if you have a demanding coral. No reflectors, they focus down on there own. use a heatsink, fans depend on how many LEDs you have and the size/efficiency of your heatsink. you can use an epoxy or you can screw the LEDs down. I would drill and tap holes and use machine screws to hole them down. 18g is plenty fine for wire. I am building a small array of just whites and using T5 for the blues, actinic and fiji purple kind of tubes. Waiting on the XPG to come in blue.

good luck
Make sure you use heat sink epoxy, tape or white paste. Also make sure the LEDS are sealed of from the water. There are 3 things that are most important #1 is heat management #2 heat management and most important is #3 heat management. My company builds LED units for commercial sites. Make sure the LEDS are current and the heat sink calculations are in tune with your LEDS, Good Luck
