Fish Tank Light – 18W Full Spectrum Clip-On LED
Plants that fade and stretch are usually short of light, and a standard room lamp gives neither the spectrum nor the consistency they need. This fish tank light clips onto the rim and delivers 18W of full spectrum LED output aimed at aquatic plant growth, in a bar you can match to tanks from 20 cm to 70 cm wide. Sunrise and sunset modes fade the light in and out rather than snapping on, which is easier on fish and on algae control.
Why fish keepers choose it
- ✔ Full spectrum output — supports aquatic plant growth
- ✔ IP68 waterproof — rated for the humid area above a tank
- ✔ Sunrise and sunset modes — gradual changes instead of a hard switch
- ✔ Six length options — 20, 30, 40, 50, 60 and 70 cm
- ✔ Clip-on fitting — sits on the tank rim with no bracket

Which length fits your tank?
Measure the outside width of your tank rim and choose the fish tank light closest to it, from 20 cm up to 70 cm. A bar slightly shorter than the tank still lights the centre well, while one that overhangs looks untidy on a rim. At 18W it suits a planted tank of modest depth; a deep or heavily planted aquarium needs more output.
Care
Wipe the lens with a soft damp cloth when it dulls, and dry the bar before repositioning it. Switch the unit off and unplug it before maintenance, and keep the driver and cable clear of splashes even though the bar itself is IP68 rated. Run it on a consistent daily photoperiod and adjust if algae builds up.
What’s in the box
1 x fish tank light, 18W full spectrum clip-on LED bar, in your chosen length.
