Marineland Aquarium LED 24 Strip Light 24"-36" Black Timer Blue White Light. Preowned and does have a couple of scratches as shown. Comes with the instruction booklet. The adjustable legs allow this to fit tanks with a length between 24 inches and 36 inches. This was previously used on a standard 29 gallon tank but can fit tanks that are smaller. Built in timer. Has a blue light setting to mimic moonlight as well as a white light for daytime use. This is not bright enough for a planted tank unless you only have low light level plants. Shipped with care. Smoke free.
