Why You’ll Love It

Here is why this LED light is so great: it comes with a timer and lets you create a natural light cycle with adjustable intensity. You can set the time to 6, 10, or 12 hours, or set it to 24/7 mode, which’ll adjust the colors based on the time of day. The LED light is full-spectrum with individual color options, and it’s also a waterproof light. You can easily adjust it to fit various tank sizes using extendable brackets. Whether you’re just starting or an experienced aquarium expert, the light offers the power, flexibility, and vibrant color spectrum your tank needs to thrive.

Usage Tips

Note: The package includes an AC-DC adapter; No additional purchases are required.

•

• Installation & Setup: Securely mount the light on the tank rim using the sliding brackets, adjusting the length and angle for even light coverage across the aquascape.

Position the light at an appropriate height above the water surface to optimize light penetration and shimmer effect without causing excessive heat or algae growth.

• Selecting Lighting Modes: Use the Default 24/7 Natural Mode to simulate a realistic day-night cycle that supports fish circadian rhythms and natural plant photosynthesis.

Switch to DIY Mode for customized lighting schedules, choosing from 6, 10, or 12-hour durations, seven vibrant colors, and five brightness levels to meet specific aquatic needs or aesthetic preferences.

Regularly monitor and adjust brightness settings to balance plant health and prevent algae overgrowth.

• Timing & Automation: Pair the light with a timer or smart plug for reliable, automated on/off cycles, reducing manual intervention and ensuring consistent lighting for your aquarium ecosystem.

Recommended lighting duration for planted tanks is typically 8 to 10 hours per day, adjusting based on plant species and tank conditions.

• Maintenance & Cleaning: Always unplug the unit before cleaning or adjusting the fixture.

Use a soft, dry cloth to wipe the light surface and brackets regularly to prevent dust and water residue buildup.

Avoid exposing the light’s internal components or adapter to water or moisture, even though it has a waterproof rating.

The separable adapter design allows for easy replacement or servicing without changing the entire unit.
