Description
Product Details

The PHILIPS TUV PL-S UV-C lamp rated 5 W emits germicidal radiation at 253.7 nm, the wavelength that neutralises the DNA of bacteria, viruses, moulds and algae. Its special glass blocks the 185 nm line: it disinfects without producing ozone.

It fits a G23 base and runs on a standard fluorescent ballast of the same wattage — a direct replacement in your steriliser, purifier or clarifier, with the unit powered off. Check the tube length: 83 mm.

Direct cross-references: OSRAM PURITEC HNS S 5W G23, PHILIPS TUV PL-S 5 W — this product, SYLVANIA —, GE Lighting —. These germicidal ranges are interchangeable: same base, dimensions and output.

Frequently asked questions

Can I handle the lamp with bare hands?

No: always handle it with a clean soft cloth (or the packaging film). Fingerprints leave grease on the quartz that blocks UV-C radiation and creates hot spots — germicidal efficacy and lamp life drop sharply. If you have touched it, clean it with alcohol before use.

Is UV-C radiation dangerous?

Yes: UV-C burns eyes and skin within seconds. Use this lamp ONLY inside a closed device (steriliser, clarifier, duct) and never look at the lit tube. Always switch off the power before any intervention.

When should it be replaced?

After about 9000 hours (≈1 year of continuous use). UV-C output fades over time: the lamp may still glow blue while its germicidal power has become insufficient. Replace it yearly to guarantee disinfection.

Which OSRAM, PHILIPS, SYLVANIA or GE references does it replace?

OSRAM PURITEC HNS S 5W G23, PHILIPS TUV PL-S 5 W — this product, SYLVANIA — and GE Lighting —: identical G23 base and dimensions, direct replacement in the same device.
