11 W UV-C aquarium lamp with timer

This 11 W UV-C lamp emits 254 nm wavelengths to reduce green water in aquariums, sumps and small ponds. A built-in timer offers four preset cycles of 3, 6, 12 or 24 hours for automated operation. The submersible rectangular glass housing is rated IP68 for continuous underwater use. Rated life reaches 10,000 hours.

Practical limits of UV-C water treatment

UV-C light only treats water that passes directly through the unit, so flow rate and contact time determine effectiveness. The lamp must be shielded inside a filter compartment or covered housing to prevent exposure to eyes, skin and tank inhabitants. Glass sleeves are fragile and require careful handling during installation and cleaning. Performance declines gradually over the rated 10,000-hour lifespan.

11 W power rating decides fit

The 11 W rating defines the lamp’s physical length of 9.45 inches and its UV output for a given water volume. Selecting a lower or higher wattage model changes both dimensions and treatment capacity, so the 11 W version suits only systems sized for that specific power level. Match the wattage to your filter housing and pond volume before purchase.

Questions about this item

Which wattage version should I pick for my tank size?

The 11 W model measures 9.45 in long by 1.38 in wide and is rated for 10,000 hours; lower wattages are shorter and rated for 8,000 hours.

What does the 254 nm UV-C output actually do inside the filter?

It emits 254 nm wavelengths that target algae and microorganisms as water passes through the sump or filter compartment, improving clarity.

How does the IP68 rating limit where I can install the lamp?

IP68 means the unit is fully waterproof and dustproof, so it can be submerged in the filter box or sump without additional sealing.
