3 choices of lighting, ignition effleurage, elbow strong leadership and easily repositionable. Excellent value for money as much more expensive in pet stores. But beware, can not put that on aquariums without plastic protection, only slips on the glass (unless you find a D system). Do not heat the water. Suitable for aquariums from 55L max for light scattering. Fish love the only blue light !!! Fun to watch
