Submersible Aquarium Light – Colour Changing Air Bubbler
Most lights sit above the waterline and do nothing for the tank beyond illumination. This submersible aquarium light goes in the water instead, where it does two jobs at once: it changes colour through a cycle and releases a steady stream of air bubbles that lifts oxygen and water movement into the tank. It is a lighting upgrade and an air feature in one piece, which suits a tank with no separate air pump.
Why fish keepers choose it
- ✔ Sits in the water — lights the tank from inside, not above
- ✔ Colour changing — a shifting display rather than one fixed colour
- ✔ Air bubbles — adds oxygen and water movement
- ✔ Two functions in one — no separate bubbler to buy or plug in
- ✔ Suits freshwater tanks — ideal as a decorative centrepiece

Will it suit your tank?
This submersible aquarium light is a decorative unit, so treat it as a feature rather than the main light for growing plants — for that you want a full spectrum bar above the water. It works well as the focal point in a small freshwater tank or as an evening display when the room lights are low. Check it sits clear of the substrate so the bubble stream is not blocked.
Care
Lift the unit out during water changes and wipe the lens with a soft cloth, since a film of algae dulls the colour quickly. Check the air line for kinks and the outlet for blockages, and never handle it while it is plugged in — switch off at the socket before you put your hands in the tank.
What’s in the box
1 x submersible aquarium light with colour changing LED and air bubble outlet.

Frequently Asked Questions
Yes, it is a submersible unit designed to sit in the tank. That is what lets it light the water from within rather than from above.
No. The bubble stream adds oxygen and movement, which is a bonus, but it does not filter the water. Keep your existing filtration running.
It is a decorative light rather than a plant light. For plant growth you want a full spectrum bar positioned above the water.
No. Switch the unit off and unplug it at the socket before any maintenance that involves reaching into the water.
It cycles through changing colours rather than sitting on one fixed shade, which is why it works well as an evening display.
Lift it out during water changes and wipe the lens with a soft cloth. An algae film builds up quickly on anything left in the water.
