Ushio G10T8 9.5W UV-C Germicidal Lamp

The Ushio G10T8 is a 9.5W low-pressure mercury-arc lamp emitting UV-C radiation at a 253.7nm spectral peak. It is designed for germicidal disinfection in water treatment, air systems, medical facilities, food processing, and laboratory research environments.

Sustained UV-C Output Over 8000 Hours

The specially formulated coating maintains high UV-C output across the rated 8000-hour life. Average depreciation is 20-25 percent at end of life, so irradiance remains stable during extended operation rather than dropping sharply after initial use.

Low-Mercury Construction With Standard G10T8 Base

High-purity lamp construction stabilises output and minimises depreciation while using a low mercury dose. The G10T8 cap fits existing fixtures for drinking water, HVAC, clean room, and phototherapy installations without modification.

Questions about this item

Does the 9.5W Ushio lamp run hot or make noise when used continuously?

The 9.5W low-pressure mercury-arc lamp produces minimal heat and operates silently because it has no moving parts.

What fixture or ballast must I already have for this G10T8 lamp to work?

You need a compatible G10T8 socket and a ballast rated for a 9.5W low-pressure mercury-arc tube.

Will this 253.7nm UV-C lamp work alongside my older G10T8 ballast from a Coralife or GE unit?

Yes, it cross-references Coralife 10 Watt, GE 29498 and Osram Sylvania G10T8 models, so it fits existing G10T8 ballasts.
