OSRAM 55031 G20T5L 4PSE UV-C Lamp

The OSRAM 55031 is a 20 W T5 linear germicidal lamp with a single-ended four-pin base designed for UV-C disinfection. It emits high radiance at 254 nm to inactivate microorganisms on surfaces, in water and in air without using chemicals. The lamp operates at 45 V and uses a low-mercury, ozone-free design with a special coating for extended service life.

Suited for professional disinfection systems

This lamp fits equipment built for single-ended T5 UV-C sources requiring a four-pin G20T5L base and 20 W power input. It is not intended for general illumination, residential fixtures or any socket that does not match the specified base and voltage. Buyers needing visible light, different wattages or alternative base types should select a different product.

No bundled accessories or software

The product is supplied as the lamp only; no ballasts, starters, mounting hardware or control software are included. System integrators must provide compatible electrical gear and safety interlocks separately. The ozone-free, low-mercury construction reduces regulatory handling burden compared with older mercury-heavy designs.

Questions about this item

Does this OSRAM 55031 lamp require a specific ballast to operate?

Yes — it is a 20 W, 45 V T5 linear lamp with a 4-pin single-ended base, so it must be paired with a ballast rated for those exact electrical values.

Can I install this UV-C lamp in a fixture that currently holds a standard T5 fluorescent tube?

No — this germicidal lamp emits 254 nm UV-C radiation and uses a 4-pin single-ended base, while standard T5 fluorescent tubes use different bases and visible-light phosphors.

How can I verify the lamp is producing UV-C output after installation?

Use a calibrated UV-C radiometer set to 254 nm; the lamp’s special coating maintains long lifetime and consistent radiance, so a stable reading at that wavelength confirms correct operation.
