Germicidal Arc Lamp 16W 50V

The Ushio G16T5 is a low-pressure mercury-arc lamp that emits UV-C radiation peaking at 253.7 nm. This wavelength effectively inactivates microorganisms such as bacteria, viruses, yeast and mould. The 16 W lamp operates at 50 V and fits a G5 two-pin base. It is suited for disinfection systems requiring this specific germicidal output.

Fits G5 two-pin ballast circuits

Installation requires a compatible G5 socket and a ballast rated for 16 W at 50 V. The lamp frees the system from chemical disinfectants by providing direct UV-C irradiation. It is not for general illumination fixtures or standard fluorescent ballasts lacking the correct voltage and pin configuration. Buyers needing visible light or alternative base types must select a different product.

Questions about this item

How long can the 16W UV-C arc run continuously before output drops?

The lamp is built for continuous germicidal duty; its low-pressure mercury arc maintains the 253.7nm peak as long as the 50V supply stays stable.

Does the 16W arc generate noticeable heat or fan noise in a small enclosure?

The low-pressure mercury arc produces minimal heat and operates silently since it has no moving parts or cooling fan.
