Philips 203117 TUV TL-D 95W HO UVC Germicidal Standard Bulb

Philips 203117 TUV TL-D 95W HO UVC Germicidal

This Philips 203117 TUV TL-D 95W HO UVC germicidal standard bulb emits radiation in the range 350-400 nm with a maximum peak at 370 nm. It features an internal reflector and is EPA approved under Philips/Signify EPA Est. No 95792-POL-1. The bulb offers almost constant UV output over its complete lifetime of 1000 hours. It is designed for professional disinfection applications requiring reliable UVC irradiance.

Replaces existing TUV T8 germicidal lamps

This bulb replaces existing TUV T8 germicidal lamps that have reached their rated 1000 hour lifetime or show degraded UV output. The jump is worth it when the current lamp no longer delivers the highest output on the irradiated area required for effective germicidal action. Its long and reliable lifetime allows maintenance to be planned in advance. It provides the best match with photo sensitizes for consistent disinfection performance.

Practical limits of UVC germicidal standard bulbs

The practical limits include the fixed 1000 hour rated lifetime after which UV output cannot be guaranteed. The specific emission range of 350-400 nm with peak at 370 nm determines the germicidal effectiveness for target microorganisms. The 95 watt power consumption and double-ended T8 form factor restrict compatibility to fixtures designed for this specific lamp type. The internal reflector directs output but does not alter the fundamental emission characteristics.
