*KeyFeatures *Upgraded High-quality LED Lights: VEVOR full spectrum 5-row LED aquarium lights feature high-quality 2835 monochrome beads, providing more uniform and stable lighting without flicker. Full spectrum lighting not only benefits your fish but also enhances visual experience, with energy-saving and long-lasting performance lasting up to 30,000 hours. *Customizable Settings: With 5 brightness levels available, you can adjust the brightness between 10% and 100% by long-pressing for step-less dimming. You can also control the white-blue (WB) ratio to adjust the color temperature, tailoring the lighting to suit different aquatic organisms such as coral reefs or fish, promoting photosynthesis and growth of aquatic plants. *All-Day Settings: Utilize the automatic gradual transition function to smoothly shift from the brightest setting within 15 minutes, or tailor the timer to run for 6/10/12 hours for daytime and 2/4/12 hours for nighttime. Power-off memory function ensures the fish tank light automatically returns to the previous mode after power restoration, maintaining consistent and stable illumination. *Durable Aquarium Light: Encased in a fully sealed 2.5mm thick ABS shell, this full-spectrum aquarium LED light offers improved heat dissipation and protection against humidity and water damage. *Wide Applications: Designed for 12-18 inch aquariums, VEVOR aquarium LED lights have 2 extendable brackets with a maximum single-side extension of 3.94 inch and dual-side extension of 7.87 inch, making them easy to install on most glass or acrylic aquarium tanks with transparent hood/lid or no, with rims or rimless.
