Product Overview
The Philips TUV T8 F17 (#264138 / #26413840) is a double-ended low-pressure mercury vapor discharge lamp engineered for targeted germicidal irradiation. It delivers consistent ultraviolet output across its operational lifespan, making it suitable for HVAC in-duct units, upper-air purifiers, residential/commercial water treatment, aquaculture/pond filtration, and clinical laboratory equipment.
Philips germicidal lamps feature an internal protective coating that stabilizes UV-C output over the 9,000-hour rated lifetime. Additionally, the specialized glass envelope effectively filters out 185nm ozone-forming wavelengths, providing pure 253.7nm disinfection without unwanted ozone generation.

Compatibility Checklist
- Lamp Technology: Verify that your system requires a germicidal UV-C discharge lamp, not a standard general-lighting T8 fluorescent tube.
- Socket Configuration: Requires standard G13 medium bi-pin lamp holders.
- Ballast & Electrical Match: Ballast must support a 16.7W lamp operating at 72V and 0.265A nominal current.
- Chamber Clearance: Confirm internal fixture dimensions accommodate a 604.0 mm maximum overall length and 28.0 mm bulb diameter.
Safety & Handling Guidelines
DANGER: Risk Group 3 UV Product. This lamp emits high-intensity ultraviolet (UV-C) radiation capable of causing immediate and severe ocular inflammation and cutaneous burns. Never operate this lamp in open fixtures or unshielded environments. Ensure power is disconnected before inspection, cleaning, or replacement.
- Handling: Wear clean lint-free gloves or handle with a clean cloth. Skin oils leave residues that degrade UV-C transmission and cause localized hotspots.
- Breakage Procedure: If damaged, ventilate the room for at least 30 minutes. Wear protective gloves to gather glass fragments in a sealed container. Do not use standard vacuum cleaners.
- Disposal: Contains 2.0 mg of mercury. Dispose of according to local, state, or federal universal hazardous waste regulations.
