The NICREW 20W Saltwater Aquarium Light is a high-performance LED reef light designed to provide optimal lighting for saltwater aquariums, supporting various marine life including fish, live rock, soft corals, and LPS corals. This light features a sophisticated combination of LEDs and a programmable timer controller to simulate natural light cycles.

- Programmable Timer Controller: Includes a day+night controller that allows adjustment of lighting spectrum and simulates gradual sunrise and fading sunset through light intensity changes.
- Versatile Coral Support: One light supports saltwater fish, live rock, soft coral, and LPS corals. For low light SPS corals, two lights are recommended.
- Disseny ajustable: Available in multiple sizes with extendable brackets to fit both rimless and framed aquariums from 18 to 24 inches in length.
- Durability Recommendation: A glass or acrylic canopy is highly recommended to protect the unit from moisture and extend its lifespan.
