UV-C water clarifier with timer

The AQ-UV357911W is a 7 W submersible lamp that emits 254 nm UV-C light to reduce green water in aquariums, sumps and small ponds. An integrated timer offers four preset cycles of 3, 6, 12 or 24 hours so the unit runs only when needed. IP68 sealing allows permanent immersion in filter compartments or top-filter boxes.

Best for tanks needing automated UV cycles

Aquarists who want hands-off clarity control will benefit from the programmable timer and up to 10 000 hours rated lamp life. The rectangular glass sleeve fits inside filter housings rather than displaying in the main viewing area. Keepers who need higher flow-through sterilisation or an in-line reactor should consider a different form factor.

7 W output at 254 nm wavelength

The lamp draws 7 watts and produces the 254 nm UV-C band specified for germicidal water treatment. This single figure determines whether the unit matches the volume and flow rate of the intended system.

Questions about this item

How often should the UV-C lamp be replaced to keep the 254 nm output effective?

The 7 W model is rated for 10,000 hours of operation, so plan on replacing the lamp after that period to maintain full germicidal intensity.

What limits continuous running time on the built-in timer?

The timer offers four fixed cycles — 3, 6, 12 or 24 hours — and the unit will not run longer than the selected cycle without a manual restart.

How much heat does the 7 W UV-C lamp add to the water during all-day use?

At 7 watts the lamp adds only a small amount of heat; the IP68-rated glass housing is designed to dissipate it safely while submerged.
