What to Compare Before Buying
- Tank thickness: This light is stated for glass edges under 11 mm thick, so measure the aquarium edge before choosing it.
- Lighting control: Compare the 10 brightness levels and 3 colour modes with the look you want for the tank.
- Power setup: The light comes with a power adapter, so check that the power arrangement matches your available socket or setup.
- Positioning: The 360° adjustable design matters if you want to direct the light more precisely over the aquarium.
Compatibility, Size and Fit
This clip-on lamp is intended for frameless aquariums with glass edges under 11 mm thick. That is the main fit check. If your tank edge is thicker than this, the clip may not suit it.
The adjustable tube and clip design give you flexibility in how the light is aimed, but the aquarium thickness remains the key compatibility point.
Before You Decide
Confirm the tank edge is under 11 mm thick, check that the 9W light output and 10 brightness levels suit your aquarium, and make sure the supplied power adapter fits your setup. The adjustable design is useful, but the size of the aquarium rim is the first thing to check.
