Philips TUV PL-L 18W/4P 2G11 - UV-C lamp for air and water disinfection (9,000 h, ozone-free)
The Philips TUV PL-L 18W/4P is a germicidal UV-C (253.7 nm) lamp designed for disinfecting air, water, and surfaces in professional and residential systems. Its compact twin-tube ( 2 x T16 ) design with a 2G11 (4-pin) socket facilitates the design of smaller units and easy replacement . It maintains a virtually constant UV-C output throughout its lifespan , eliminating the need to oversize the system to ensure effective disinfection. Philips' special glass filters the 185 nm wavelength , preventing ozone generation , and the protective internal coating minimizes the depreciation of the effective light output. It is a proven choice for ducted air handling units , stand-alone purifiers , water purification and treatment , as well as for disinfecting chambers and surfaces in healthcare and industrial environments.

Frequently Asked Questions
-
Does it generate ozone? No. Philips' special glass filters out the 185 nm wavelength responsible for ozone formation.
-
What equipment do you need? Requires compatible auxiliary equipment/driver for 4-pin PL-L germicidal lamps (electronic).
-
When should I replace it? Although the nominal life is 9,000 h, to maintain the UV-C dose some manufacturers recommend preventive replacement before the end of life in critical applications.
-
Is it suitable for viewing or directly irradiating people? No. It is a high-risk UV-C product: use only in enclosed equipment that prevents exposure.
Safety and usage recommendations
-
UV-C protection: avoid all skin and eye exposure. Use the lamp only in enclosed or UV-shielded equipment.
-
Handling and end of life: In case of breakage, ventilate for 30 minutes and manage waste according to local regulations.
-
Dimensional compatibility: Check the dimensions (up to 225 mm total length) and the 2G11 base on your equipment.
