Full Spectrum: The fish tank light contains white light, blue light and UV Purple light. The vivid lights can reproduce the real colors of objects to relieve the visual fatigue, and thus improve the comfort of the environment. Auto On/Off: With a built- in timer, the submersible aquarium tube light provides 3 optional lighting durations: 6h, 10h and 12h. Create a natural environment to give your fish a sound sleep. For 24" to 32" Tanks: With an extendable bracket; the LED aquarium light always stays steady on the fish tank. Work best on tanks of 24 to 32 inches long.
