Germicidal UV-C Lamp 17 W

The Philips 133405 TUV 17T8 is a double-ended fluorescent bulb that emits short-wave UV-C radiation peaking at 253.7 nm. It is designed for professional disinfection in settings such as universities, hospitals, laboratories and fish ponds where reliable germicidal output is required.

Installation and Common Issues

The lamp fits standard T8 sockets and operates like a typical fluorescent tube, but it radiates UV-C light that is harmful to skin and eyes. A warning sign on the lamp indicates this hazard; fixtures must fully enclose the bulb and interlocks should prevent accidental exposure during relamping.

Pre-Order Checks

Verify that your ballast and fixture are rated for a 17 W T8 tube and that the enclosure blocks 185 nm ozone-forming radiation, which the lamp glass already filters. Confirm the application can schedule maintenance around the 9,000-hour useful lifetime and that local regulations permit UV-C germicidal devices.

Questions about this item

How can I verify the 17 W TUV 17T8 is emitting the correct 253.7 nm UVC output after installation?

The lamp carries a warning sign that indicates it radiates UVC; a protective inside coating keeps the 253.7 nm output nearly constant over the 9,000-hour lifetime.

What comes with the Philips 133405 bulb and what must I purchase separately?

The box contains the double-ended TUV T8 F17 germicidal lamp itself; a compatible T8 ballast and fixture are not included and must be bought separately.

Should I choose the standard 17 W version or a High Output variant for my application?

High Output versions deliver more UVC per lamp length, letting you reduce system size, while the standard 17 W model provides 9,000 hours of reliable output for typical installations.
