2. Product Features
- Full Spectrum Lighting: Features 6500 K white light, 450 nm blue light, 520 nm green light, and 660 nm red light. Provides LUX: 1200, PAR: 25, CRI: 91. These vivid lights accurately reproduce the natural colors of aquatic objects and significantly improve photosynthesis and growth of tank plants.
- Two Lighting Modes: Easily switch between Daytime Mode (all lights on) and Night Mode (blue light only) by short pressing the 'M' button. Hold the 'M' button for 3 seconds to turn all lights off. This simulates natural sunrise and sunset cycles, benefiting fish health and sleep patterns.
- Six Intensity Levels: In Daytime Mode, use the 'N' button to control the brightness of the blue light and the 'D' button for all other lights. In Night Mode, the 'N' button adjusts the luminance of the blue light.
- Automatic On/Off Timer: A built-in timer offers three optional lighting durations: 8 hours, 10 hours, and 12 hours. The timer operates within the initial 8, 10, or 12 hours of a 24-hour cycle, creating a consistent natural environment.
- User-Friendly Design: Optimized for 1 to 5 gallon fish tanks. Includes a 3-foot long USB cable for DC power (adapter not included). The flexible gooseneck allows for easy adjustment of the light angle.

3. Setup Instructions
- Unpack the Light: Carefully remove all components from the packaging.
- Attach the Clip: The light features an adjustable clip. Loosen the screws on the clip to fit it over the edge of your aquarium. Ensure the clip is securely fastened to the tank wall. The clip is designed to fit tank walls with a thickness of up to 0.55 inches.
- Position the Light: Utilize the flexible gooseneck to position the light head directly over your aquarium at the desired angle and height.
- Connect Power: Plug the USB cable into a compatible USB power adapter (not included). For stable lighting, a 5V 2A adapter is recommended. A 5V 1A adapter may cause flickering at high brightness, which can be resolved by reducing the brightness.
