7W USB Clip-On Aquarium Light, 3-Mode Dimmable LED Fish Tank Lamp

Make Nano-Tank Lighting Easier to Aim and Easier to Live With

This 7W USB clip-on aquarium light combines a flexible gooseneck, three light modes, and 10-step brightness control in a compact fixture for small rimless tanks. Adjust the direction, color presentation, and intensity without covering the aquarium with a full-length hood light.

Core Benefits

• Three light modes: Switch among the documented light-source combinations to change the appearance of fish, plants, and décor.
• 10 brightness levels: Short presses move through ten steps, while holding the plus or minus button provides continuous adjustment for more precise viewing comfort.
• Flexible gooseneck: Bend and rotate the lamp to fill a dark corner, reduce direct glare, or reposition the light as the aquascape changes.
• USB 5V/2A power: Connect to a compatible phone adapter, power bank, or computer USB source. Confirm whether a wall adapter is included.
• Compact rimless-tank fit: The clip is documented for unframed glass up to 6 mm, making the light suitable for desktop, betta, shrimp, and nano aquascape tanks.

How to Use

Secure the clip to suitable rimless glass, aim the lamp above the water, connect a 5V/2A USB supply, choose a light mode, and adjust brightness. Keep the controller and USB connection away from splashes and condensation.

What to Know Before Buying

Despite the folder name, the four-button controller shows brightness up, mode, brightness down, and power only. No timer setting, automatic on/off schedule, 24/7 cycle, or power-loss memory is documented. This listing therefore does not claim a timer.

The lamp cover is splash resistant, but the fixture is not submersible and has no verified IP rating. “Full spectrum,” PAR, PPFD, flicker-free performance, and guaranteed aquatic-plant growth are not supported by test data.
