Product Description
254nm UV-C germicidal T8 lamp for air, water, and surface sanitation in professional fixtures.
SOSCleanroom
Overview

The Osram Sylvania G30T8 is a 30W, 36-inch UV-C germicidal lamp designed for use in properly engineered UV fixtures and systems. It emits 254nm UV-C, a wavelength commonly used to inactivate microorganisms in air and water purification and in controlled surface-treatment applications. SKU: G30T8 (21080).

  • Electrical: 30 Watts, 96 Volts
  • Spectral Output: 254nm (UV-C germicidal)
  • Base Type: Bi-Pin (T8 format)
  • Length: 36 Inches
  • Average Life: 8,000 Hours
  • UPC: 4008321398888
  • Case Quantity: 25 Bulbs
Primary Applications
  • Air and water purification systems
  • Food processing and medical facilities
  • Air conditioning/HVAC sanitation programs
  • Pharmaceutical production and clean rooms
  • Sterilization and disinfection processes (fixture and procedure dependent)
Handling Tip 
UV-C can damage eyes and skin. Operate germicidal lamps only in properly designed fixtures that shield UV-C radiation. Avoid touching the glass with bare hands; use clean nitrile gloves and/or a lint-free wipe to minimize residue.
Industry Update:
In July 2025, Ushio announced an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps business, with closing expected by the end of March 2026. During and after transitions, customers may see changes such as labeling, packaging, part-number presentation, and distribution channels. Best practice: qualify replacements by the manufacturer code and critical specs (30W, 36" T8 bi-pin, and 254nm) to maintain continuity.

Why 254nm UV-C is Germicidal
Germicidal UV (often called UVGI or GUV) uses UV energy to inactivate microorganisms by damaging their genetic material (DNA and/or RNA). When microbes absorb UV-C, photochemical reactions can prevent replication—reducing infection risk and contamination potential.
254nm is widely used because it is close to the strong absorption region of nucleic acids and is efficiently produced by traditional germicidal lamp technology. In practice, performance depends on delivered dose (also called fluence): the UV intensity at the target multiplied by exposure time.
Where Germicidal UV is Used
  • Air treatment: upper-room UVGI, in-duct UVGI, and air-handler applications where air passes through a controlled UV field.
  • Water treatment: UV reactors that deliver validated dose to inactivate microorganisms without chemical residue (system dependent).
  • Surface programs: controlled disinfection steps where UV can reach surfaces directly (UV is line-of-sight; shadows reduce effectiveness).
  • Facilities: food processing, healthcare, HVAC hygiene, pharmaceutical production, and controlled environments.
Engineering: What a T8 Germicidal Lamp is
A germicidal T8 lamp is typically a low-pressure mercury discharge source optimized to emit UV at 254nm. Unlike general lighting fluorescents, germicidal lamps are designed to deliver UV output (not visible light) and are used in fixtures engineered for UV performance and shielding.
  • Warm-up and stabilization: UV output rises as the lamp reaches thermal steady-state; many systems specify a warm-up period before measurements or critical use.
  • Output depreciation: UV output decreases with operating hours and with surface fouling (dust/films), which is why maintenance and scheduled replacement are operational requirements.
  • Ballast/fixture dependency: electrical operation and starting behavior are driven by the UV fixture and ballast—always follow OEM fixture requirements for compatibility.
  • Ozone note: some UV lamps are designed to emit shorter wavelengths (e.g., ~185nm) to generate ozone; this product is specified by its 254nm output—verify ozone requirements at the system level before substituting lamps.
Dose (Fluence): The Practical Key to “Does it Work?”
Germicidal effectiveness is governed by the delivered UV dose at the microorganism. Dose depends on distance, fixture geometry, airflow or water flow rate, exposure time, and the microbe’s susceptibility. “Same lamp, different fixture” can produce materially different results.
  • Air systems: dose is affected by air changes, mixing, and residence time in the UV zone (upper-room vs. in-duct designs).
  • Water systems: UV transmittance (UVT), reactor hydraulics, and sleeve cleanliness drive delivered dose.
  • Surfaces: UV is line-of-sight; shadows and soils reduce effective dose at the target.
Safety & Compliance
  • Eye/skin hazard: UV-C exposure can cause injury. Use only in fixtures designed to shield UV and follow all OEM interlocks and procedures.
  • Operational controls: signage, access controls, PPE (as applicable), and commissioning are typical in professional UVGI deployments.
  • Claims discipline: real-world results are application-specific and dose-driven; treat UVGI as part of a layered contamination-control strategy.
Cleanroom Considerations
  • Controlled changeout: treat lamp replacement as a maintenance event—minimize packaging debris and handle with clean nitrile gloves.
  • Keep the lamp clean: residues can bake onto the glass/quartz and reduce UV output; use lint-free wipes appropriate for controlled environments.
  • Program management: track operating hours and replace on schedule to maintain validated performance in critical areas.
Industry Update: ENI Business Transfer (Expected Close by End of March 2026)
Ushio announced an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps business, with closing expected by the end of March 2026. For buyers, the control plan remains the same: qualify by manufacturer code, form factor (36" T8 bi-pin), and required wavelength (254nm), and keep maintenance records for traceability.
