WOW thats a lot of LEDs!!! I have only been in there a few times since he bought it. He is making slow progress with the tanks. He is slowly converting all lights to LED lights and tanks are in decent shape. Unlike the previous owners. He is pretty friendly and will greet you at the door. <--- important to me!... My only complaint is the store is a little cluttered. Lots of used fish tanks for sale and desk area is kinda messy but the livestock tanks are all in good shape and healthy. I bought a RBTA about 3" across for $45 recently. It was all red with no greem. I thought that was a decent deal. Thats my review of that store LOL back to subject

The way he has it set up with the LEDs seems very simple to build. He told me how to do it while I was there. Seems very simple. The heat sinks are actual heat sinks and they are squares made to fit 1 led each.
