Product Identity

The Antique Light Bulb Co. 7W T12.5 G23 UV-C Germicidal Bulb is a 7-watt ultraviolet lamp built for germicidal sterilisation. It uses a G23 two-pin base and a single T5 tube design to deliver UV-C irradiance at 254nm. The outer glass tube absorbs lower wavelengths to suppress ozone formation during operation.

Suitable Applications

This bulb suits water treatment, air purification and surface disinfection systems that accept a G23 base and require ozone-free output. It is not for buyers who need a standard visible-light lamp, a different base type or a higher wattage UV-C source for larger chambers.

Capacity And Headroom

Rated life reaches 8000 hours of continuous germicidal output at the specified 254nm wavelength. The 7-watt power level limits coverage to smaller enclosures or lower flow rates where the irradiance dose remains effective. Longer runs or larger volumes will exceed the practical intensity this lamp can provide.

Questions about this item

Does this 7 W T12.5 G23 germicidal bulb need a separate ballast to operate?

Yes — the G23 two-pin base is designed for magnetic or electronic ballasts that supply the correct starting voltage and regulate the 7 W discharge current.

Can I keep my existing G23 fixture and simply swap in this UV-C lamp?

The lamp fits any standard G23 socket, but the fixture must be rated for UV-C output at 254 nm and must not contain materials that degrade under short-wave ultraviolet exposure.

How can I verify the bulb is emitting UV-C after installation?

A calibrated UV-C radiometer pointed at the lamp should read irradiance at 254 nm; the rated 8 000-hour life means output will remain within specification for that period under normal cycling.
