MagicalPet Aquarium 18W White&Blue&UV Purple LED Light For 45-60cm Fish Tank HS-L450

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.

For 18" to 24" Tanks: With an extendable bracket, the LED aquarium light always stays steady on the fish tank. Work best on tanks of 18 to 24 inches long.
