I have been trying to do the gallery here but it does not let me. it just sends me back to log in again and again, endless loop at this point.
for your tank I would suggest two to three of the units. depending on how you have your tank set up i.e how close to the walls you are at the ends of your tank, what I did for the frag tanks and my own was one light for each two by two foot section of reef. my tank is 24 deep by 5 feet long but I stop my coral six inches from one end and my over flows take up six inches of the other, so two worked for mine. I sold each light I made for the frag tank at $550 so to do your tank with two would be $1100 or three would be $1650 if you want to do the work of assembly then the price drops depending on how much you want to do. the leds will run you $300 to $456 per unit depending on how many you buy at one time. also you can more times then not find a heat sink that will work at your local surplus center along with a power supply for pennies on the dollar but if not I can also set you up with both of them. if you can solder then you can buy the components for the board from digikey and save some money(you do not have to use a PCB if you do not want it just makes it a cleaner install to use the PCB I will sell you an unpopulated PCB. or you can buy a populated and tested board from the guy that makes them for me if you want. the acrylic you are better off going to your local plastic store and having it made for you but I can also sell you that if you want.
Luxeon LEDs - 7007-PWC-10-3 Luxeon Rebel Star - White Tri-Emitter, 540 Lumens @ 700mA
look here for the whites and I can set up the blues for you to order. or I can set up both the whites and blues for you at a $25 cost each there are 6 each per unit for a total of 12 on each heat sink. I am about to make an very large order in the order of 1000 for a friend so I will be able to get them for $25 each.
I hope this helps, I am trying to set up a web site that will allow anyone to buy everything it takes to make one from one place. I just do not have it up yet. sorry but I will help anyone that wants one. you just have to be patience because this is just a hobby for me and not what I do for a living so it may take a little bit of time to get around to helping everyone. and a new order for 50 lights is going to take a lot of my free time.
