Programmable LED Aquarium Light with Thermometer for 20-Inch Tank

Temperature Alarm Feature: The aquarium light monitors water temperature in real-time, automatically sounding an alarm for low or high temperatures. No need to worry about fish or shrimp being affected by extreme temperatures. Unlike traditional heaters or thermometers, our light offers consistent monitoring and timely alerts, enhancing aquatic environment care.

Power Failure Memory Function: Aquarium plant light with built-in CR1220 button battery retains the previous mode setting after unplugging or accidental power outage. No need to reset time and light settings—simply plug back in and continue where you left off. Installation of the battery is required upon receipt to ensure full functionality.

Programmable Design: With a timer and 24/7 cycle modes, our planted aquarium light allows for customizable WRBG colors and 20 brightness levels. The 24/7 cycle mode offers 5 time periods for choosing sunrise, daylight, sunset, and moonlight color and brightness with a 15-minute gradient transition between each phase, perfectly mimicking nature. The 24/7 cycle function does not require daily operation.

Customizable Colors: In addition to the 7 pre-set colors—red, green, blue, orange, cyan, pink, and yellow—and cycling and full-spectrum lighting, the WRGB 4 colors and 20-level brightness can be freely combined and adjusted to create your favorite colors and brightness levels. DIY settings are automatically saved in the system for convenient future use.

Extreme Durability: IP68 waterproofing and 5054+2835 lamp beads with an efficiency of up to 93% ensure that the aquarium water remains clear, while the colors of aquatic plants appear more vibrant. Suitable for glass or acrylic aquariums, this light supports plant growth with medium to low light requirements.
