This is a custom made product, made by Catalina Aquariums for attaching to the underside of your tank hood. It is 42 inches long and holds up to 8 - 36 inch bulbs. It is constructed of stainless steel, and includes moonlights in the center that operate on a separate dimmer switch. The fixture allows for the use of actinic and bright whites on two separate timers (included) to simulate dawn to dusk. This hood cost over $225 new. Send me a text to 858.610.4747 and I will shoot you a pic.
I am right off I-5, Loma Santa Fe exit but will meet anywhere in the area.
