Product Overview

The Sylvania 23392 GFT36DL/2G11/SE/O is a 36-watt 106V UV-C germicidal lamp — a specialized disinfection source, not a visible lighting lamp. Operating at 253.7nm ultraviolet wavelength, this lamp delivers germicidal energy in the UV-C band most effective for inactivating bacteria, viruses, mold, and other microorganisms in air, water, and surface disinfection systems.

The O designation (ozone-free) indicates this lamp uses a special quartz envelope that blocks the 185nm wavelength responsible for ozone generation — making it appropriate for occupied or semi-occupied spaces, HVAC duct treatment systems, and applications where ozone accumulation must be avoided. The 2G11 4-pin base is the same physical format used by the Sylvania Dulux L fluorescent lamp series, but this lamp operates on a UV-C ballast at 106V and is not interchangeable with fluorescent Dulux L lamps. Verify your equipment is specifically rated for germicidal UV-C lamps before ordering.

At 8,000-hour rated life, this lamp is appropriate for continuous-duty air and water purification systems with annual or semi-annual lamp replacement schedules. UV-C germicidal output declines over lamp life — follow equipment manufacturer guidelines for maximum replacement intervals to maintain effective germicidal dosage.

Why Choose This Product

• 253.7nm germicidal UV-C peak — maximum microbial inactivation efficiency: The 253.7nm wavelength is the peak of the germicidal action spectrum for DNA/RNA disruption in bacteria, viruses, and mold — the most effective UV-C wavelength for air, water, and surface disinfection.
• Ozone-free (O designation): Blocks 185nm ozone-generating wavelength — safe for use in HVAC systems, occupied environments, and applications where ozone must be avoided.
• 8,000-hour rated life: Long service life for continuous-duty germicidal systems — supports annual replacement schedules in most commercial air and water treatment applications.
• 2G11 4-pin base — standard germicidal equipment format: The 2G11 base is widely used in germicidal UV-C equipment from major OEM manufacturers — direct replacement in compliant germicidal fixtures.
• Sylvania professional quality: Sylvania germicidal lamps are designed for consistent UV-C output throughout rated life — critical for maintaining effective germicidal dosage in validated disinfection systems.

Applications

• HVAC air purification systems — Duct-mounted and air handler UV-C systems for commercial, healthcare, and institutional HVAC disinfection.
• Water treatment and purification — UV-C water treatment reactors for potable water, wastewater, aquaculture, and laboratory water systems.
• Medical and laboratory environments — Biosafety cabinets, clean rooms, laboratory workbenches, and medical facility air treatment systems.
• Surface disinfection systems — Automated UV-C surface treatment equipment in healthcare, food processing, and pharmaceutical manufacturing.

Critical Safety Information

WARNING — UV-C RADIATION HAZARD. This lamp emits ultraviolet radiation that can cause severe eye and skin injury. Read all safety information before handling or installation.

• Never look directly at an operating UV-C lamp. UV-C radiation causes photokeratitis (arc eye) and severe corneal injury. Even brief exposure without eye protection can cause permanent damage.
• Never expose skin to UV-C radiation. UV-C causes severe sunburn-equivalent skin injury. Cover all exposed skin and wear UV-rated protective equipment during operation or when working near operating lamps.
• Do not touch the lamp envelope with bare hands. Skin oils cause hot spots leading to premature lamp failure. Use clean gloves or lint-free cloth during handling and installation.
• Do not exceed rated voltage (106V). Verify equipment supply voltage before installing.
• This is not a visible light lamp. Do not install in standard fluorescent fixtures — requires a UV-C rated ballast at 106V.
• Inspect envelope for cracks before installation. Do not use a damaged lamp. Allow lamp to cool completely before handling or replacement.
• Mercury content: This lamp contains mercury. Dispose of per local and state lamp recycling regulations. Visit lamprecycle.org.
