I bought 2 of these for my 135 gal Oscar tank. They are Beamsworks great light. I'm thinking of picking up another one for the tank. Great price for 2 is only $72.00 and one by it self for $40.00. I bought a 48'' and a 36'' from the same seller for my 75gal and my 30gal. There is also a 72'' model from Beamsworks.
