Ushio G6T5 6 W germicidal UV-C lamp 8000 h

Ushio G6T5 germicidal UV-C lamp

The Ushio G6T5 is a 6 W low-pressure mercury-arc lamp that emits UV-C radiation peaking at 253.7 nm. It is designed for germicidal disinfection systems in commercial, industrial or laboratory settings where targeted ultraviolet output is required. The lamp delivers a rated life of 8000 hours. Its construction uses high-purity materials to stabilise UV output and limit depreciation to an average of 20-25 % at end of life.

Integration into a disinfection system

The lamp fits fixtures built for standard G6T5 low-pressure mercury-arc bulbs and operates on compatible 6 W ballasts. Its specially formulated coating maintains high UV-C output over the full 8000-hour life, reducing the frequency of relamping cycles. A low mercury dose meets environmental demands without additional handling complexity. No external cooling or specialised enclosures beyond standard UV-C safety shielding are described in the specifications.

Suitability and alternatives

This lamp suits engineers and facility managers who need a 6 W UV-C source with a documented 8000-hour lifespan and stable 253.7 nm peak output. It is not intended for general illumination, visible-light curing or applications requiring higher wattage or different spectral peaks. Buyers needing longer life, higher power or alternative form factors should evaluate other germicidal lamp types.
