Ushio GPX11 11.8 W germicidal lamp

The Ushio GPX11 is a low-pressure mercury-arc lamp that emits UV-C radiation peaking at 253.7 nm. It draws 11.8 W and is rated for 8000 hours of operation. The lamp is designed for germicidal disinfection applications where targeted UV-C output is required.

Capacity and headroom

At 11.8 W the lamp provides a defined UV-C dose suitable for small-scale air, surface or water treatment units. Output declines gradually over the 8000-hour life, so systems needing constant intensity will require scheduled replacement. It is not suited for high-throughput installations that demand higher irradiance or longer continuous runs without maintenance.

Questions about this item

Will the 11.8 W arc lamp run on the same ballast as my old 11 W UV-C lamp?

The lamp is rated at 11.8 W; verify that your existing ballast supports this exact wattage before installing.

How can I confirm the 253.7 nm output is active after installation?

Use a UV-C radiometer calibrated for 253.7 nm to measure the irradiance; the lamp emits peak radiation at that wavelength.
