Product Description
Compact self-ballasted UV-C germicidal lamp with E17 intermediate base for enclosed fixture applications.
 
Overview

The Ushio GTL-3G is a compact 3W UV-C germicidal lamp designed with an E17 intermediate screw base for systems that require a threaded installation format. Unlike linear germicidal tubes that require external ballasts, the GTL-3G is typically used in engineered enclosed devices where compact size and screw-base compatibility are required.

This lamp emits primarily at 253.7 nm (UV-C), the germicidal wavelength produced by low-pressure mercury discharge lamps. It is intended strictly for use in fixtures designed to prevent direct exposure to UV radiation.

Key Highlights
  • Lamp Type: Low-pressure UV-C
  • Wattage: 3W
  • Base: E17 (Intermediate screw)
  • Primary Emission: 253.7 nm (UV-C)
  • Configuration: Compact screw-in format
  • Application Class: Enclosed germicidal systems
Typical Applications (Enclosed Systems Only)
  • OEM cabinets and device-level germicidal assemblies
  • Specialty equipment requiring E17 screw-base UV lamp format
  • Engineered systems with shielding and interlocks
Critical Safety Notice
UV-C radiation is hazardous to eyes and skin. This lamp must only be operated in fixtures designed to prevent exposure. Never operate in open air or without proper shielding. Lamp contains mercury; handle carefully and dispose in accordance with local regulations.
Industry Update (Ushio & ENI Continuity)
Ushio has signed an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps (ENI) business, with closing expected by the end of March 2026. Customers may observe branding or packaging updates during transition. SOSCleanroom continues to support specialty lamps and assists customers with part-number and specification validation.

UV-C Germicidal Lamp Science

GTL-3G operates as a low-pressure mercury discharge lamp. When energized, mercury vapor emits strongly at 253.7 nanometers, a UV-C wavelength commonly used in engineered systems for controlled irradiation applications.

Delivered UV output depends on temperature, operating current, and enclosure reflectivity. System-level design—including shielding, airflow, and exposure time—determines effective performance.

Engineering & Integration Notes
Screw-base UV lamps must be matched to compatible voltage and fixture design. Confirm fixture rating, thermal management, and shielding. Never substitute a visible-light E17 lamp into a UV system or vice versa.
Safety & Regulatory Considerations
UV-C radiation can cause serious injury to eyes and skin. Operate only within fully enclosed, interlocked systems. Lamp contains mercury; follow proper handling and disposal procedures in accordance with local and federal regulations.
Industry Update (Ushio & ams OSRAM ENI)
Ushio has signed an agreement to acquire ams OSRAM’s Entertainment & Industry Lamps business, with closing expected by the end of March 2026. Branding updates may occur during transition while specifications remain consistent. SOSCleanroom continues to support specialty lamps and assists with continuity validation.
