Three large heat sinks that are 20" square each. 70 cree LEDs on each one. Comes with ballasts, power supply, 70" long hanging bracket, and spare electrical components. Many of the diffusers have popped off and will need to be reglued if you want them. These may require some DIY electrical know how. I won't be able to help much. These came with a bundle of aquarium equipment that I bought and eventually decided I wanted something else.

open to trades

I also have very large AC pumps for sale.
