Purpose and fit

The Antique Light Bulb Co. 11w G23 2-Pin Germicidal Bulb 23398 is a UV-C lamp that emits 254nm irradiance for sterilisation tasks. It is built for fixtures that accept a G23 two-pin base and a single T5 tube.

Installation context

The bulb slots directly into a compatible G23 socket without extra wiring or ballast changes. Its outer glass tube absorbs lower wavelengths, suppressing ozone formation and removing the need for additional ventilation hardware.

Who it suits

Facilities that require ozone-free UV-C disinfection in a standard G23 fixture will find the 8000-hour rated life practical. Buyers needing a different base type, higher wattage or a non-germicidal light source should look at other options.

Questions about this item

How long does the 11w germicidal bulb last before the UV-C output drops below effective levels?

The lamp is rated for 8000 hours of service life, after which UV-C irradiance at 254nm typically declines.

Does the 11w G23 bulb generate noticeable heat or ozone during continuous all-day operation?

The special outer glass absorbs lower wavelengths, suppressing ozone formation, and the 11w power draw keeps heat output low.

What fixture or ballast must I already have to run this 2-pin G23 germicidal bulb?

A compatible G23 2-pin socket with the correct ballast for an 11w T5 UV-C lamp is required.
