SYLVANIA 21086 | G30T8/OF HNS PURITEC® 30W Germicidal UV-C Short-Wave Tube Light

The Sylvania 21086 (G30T8/OF HNS) PURITEC® is a commercial-grade, high-intensity **30W germicidal ultraviolet-C (UV-C) discharge lamp** engineered specifically for localized biological sterilization in medical environments, clean-room laboratories, HVAC air disinfection channels, and secondary water purification systems. Outfitted with standard **G13 medium bi-pin bases** and a **36-inch linear T8 tube factor**, this special-purpose module operates at a **96V running threshold** (.365A current draw) to emit short-wave ultraviolet energy peaking precisely at **253.7nm**. Crafted by OSRAM/Sylvania using high-purity, ozone-free (OF) translucent quartz glass, this lamp filters out lower vacuum-UV wavelengths to prevent toxic ozone gas development. Offering an effective **8,000-hour rated operational lifecycle**, it provides non-chemical, eco-friendly pathogen inactivation by destroying the micro-organic DNA structures of floating viruses, bacteria, and mold spores.

PURITEC® Photo-Chemical Inactivation and Ozone Protection

Sylvania HNS PURITEC® technology incorporates advanced internal coatings inside a specialized low-pressure mercury discharge frame to yield reliable, highly targeted UV-C irradiance. The molecular composition of the tube blocks vacuum-ultraviolet rays below 200nm, eliminating the dissociation of oxygen molecules to successfully suppress dangerous ozone generation ($O_3$) in enclosed clinical workspaces. Operating with regular linear fluorescent physical characteristics, this tube light emits constant ultraviolet intensity across its **8,000-hour service lifespan**, providing predictable biological treatment levels and safeguarding delicate equipment parts from accelerated oxidation wear.

• Targeted Germicidal Peak (254nm Wavelength): Focuses over 85% of total radiometrical energy output into the peak DNA/RNA absorption band, destroying the reproductive mechanisms of ambient pathogens.
• Ozone-Free Clear Glass Shielding: Filters out deep-vacuum ionization rays, making it an excellent match for unventilated biological safety cabinets, hoods, and public areas.
• High-Efficiency Output Uniformity: Advanced glass layering limits envelope solarization, ensuring a stable, non-degrading baseline flow of sterilizing UV microwatts.
• Universal Burning Angle: Engineered to mount safely at any physical angle or layout pathway inside complex commercial HVAC duct modules or liquid purifiers.

System Integration, Ballast Matching & Operational Safety

• Severe Short-Wave Radiation Warning (Risk Group 3): This medical-grade lamp emits powerful short-wave UV-C energy that causes immediate, painful photokeratitis (corneal eye burns) and severe erythema (skin blistering). **Never operate this lamp within a direct line of sight without protective shielding.** Personnel must utilize UV-opaque safety face shields, heavy protective garments, and thick safety gloves if adjusting live equipment. Standard window glass or clear polycarbonate shields can block these wavelengths.
• Oils and Handling Safeguards: Never handle the clear quartz tube with bare hands. Fingerprint oils deposited on the glass will bake into the surface during operation, causing severe thermal hotspots that lead to solarization and early tube failure. Always handle using lint-free cloth or latex-free gloves. If accidental contact occurs, wipe the sleeve with an isopropyl alcohol swab before striking the arc.
• Electrical Ballast Compatibility: This lamp requires a certified current-limiting electronic or core-and-coil ballast designed for G30T8 systems with an open-circuit starting threshold of at least 176V. Operating this lamp outside its designated 0.365A current profile can cause extreme overheating or premature cathode burnout.
• Mercury Recycling Guidelines: Like standard fluorescent fixtures, this UV-C module contains trace mercury amalgam for vapor excitation. It must not be thrown into regular commercial landfill bins. Ensure spent lamps are processed safely via regional hazardous waste collection programs or certified reclamation centers. Visit **www.lamprecycle.org** for legal disposal regulations.
