Fluvial Eco Bright LED Aquarium Strip Light is a sleek, compact and energy-efficient lighting system that replicates natural daylight and moonlight. Made of lightweight extruded plastic, the fixture has a very low profile design. Both ends of the light have extendable ABS leg supports that expand to fit wider tanks. They can also be completely removed so the fixture can be placed directly on a glass canopy for an even lower profile. The LED has 3-setting switch: ON (day), ON (night) and OFF and is designed to last 20,000 hours, providing over 5 years of lighting under normal operation.
