Full Spectrum: The fish tank light contains 6500 K white light, 450 nm blue light and 660 nm red light. LUX: 2000; PAR: 40; CRI: 90. The vivid lights can reproduce the real colors of objects to relieve the visual fatigue, and thus improve the comfort of the environment.

2 Lighting Modes: Short press the M button repeatedly on the fish tank light to switch between daytime and night modes. Hold the M button for 3 seconds to turn all lights off. Simulate natural sunrise and sunset to energize your fish and give them a sound sleep.

6 Intensity Levels: Daytime Mode (all lights are on): Press the W button to control the brightness of white and red lights and press the B button to control that of the blue light. Night Mode (only blue light is on): Press the B button to adjust the luminance.

For 6" to 10" Tanks: With an extendable bracket (min length: up to 6"; max length: up to 10.5"), the LED aquarium light always stays steady on the fish tank. Work best on tanks of 6 to 10 inches long.

Heavy-duty Design: FCC-certified aquarium light. The clear board is strictly sealed with silicone to keep out moisture or droplets. Solid aluminum shell can accelerate heat dissipation. The long-lasting bulbs and ETL-certified adapter ensure safe and continuous lighting.
