Philips TUV 11W 4P SE Germicidal Lamp

The Philips TUV 11W 4P SE is a double-ended UV-C germicidal lamp designed for professional disinfection systems. It suits facilities such as hospitals, laboratories and water-treatment plants that require reliable microbial control. The lamp operates at 11 watts and emits short-wave ultraviolet radiation peaking at 253.7 nm. Special lamp glass blocks the 185 nm wavelength that creates ozone.

Thermals noise and power draw

At 11 watts the lamp draws minimal power and generates low heat during normal operation. A protective inside coating maintains steady UV output across the rated 9000 hour lifetime. The design produces no audible noise because it has no moving parts. EPA establishment number 95792-POL-1 confirms regulatory compliance for the intended applications.

Sustained load behaviour

The coating technology delivers almost constant UV-C output over the full 9000 hour service life rather than fading early. This predictable depreciation lets maintenance teams schedule replacements in advance without unexpected drops in disinfection performance. The lamp is not suited for general illumination or residential use where visible light is required. It also lacks the higher output of High Output variants for compact system designs.

Questions about this item

How do I fit the 4-pin SE base into the fixture without damaging the pins?

Align the keyed 4-pin base with the socket, press straight in until seated, and avoid twisting the lamp.

When should I plan to replace the lamp to keep UV-C output effective?

Schedule replacement at 9,000 hours; the protective coating maintains steady output until end of rated life.

What limits continuous operation before UV-C intensity drops off?

The 9,000-hour useful lifetime is the first limit; after that UV-C output at 253.7 nm declines.
