LSE Lighting 18" 4-Pin 254nm UV-C Replacement Bulb — ATS GDS-8 Compatible, EPA-Registered Germicidal Lamp

LSE Lighting's 18-inch 4-pin UV-C replacement bulb emits a 254nm wavelength designed to fit ATS GDS-8 and similar ultraviolet systems.

This replacement lamp is engineered to match the physical and electrical specifications of several ATS-series fixtures, giving technicians and facility managers a drop-in option when original-brand lamps are unavailable. The lamp uses a standard 4-pin base and a 450mm length to ensure reliable seating in compatible assemblies, and is produced under LSE Lighting’s EPA-registered manufacturing to uphold consistent output and lifespan expectations.

Will this bulb physically fit my ATS GDS-8 or similar fixture?

The LSE Lighting replacement is built to the same nominal length and base configuration as the ATS GDS-8 bulb, so it installs like the original in most compatible fixtures. Verify the fixture model and the 4-pin socket before ordering to prevent mismatches.

• Compatible reference models: ATS GDS-8, DWS-8V, EV-8E, SE-8V, SL-5, SL-8, SL-8V

What wavelength and performance can I expect from this lamp?

This lamp emits ultraviolet light centered at 254 nm, the common germicidal range used in many UV-C systems. It’s specified to deliver consistent UV output suitable for the systems listed, but actual on-site performance depends on fixture design and operating hours.

• Nominal output at 254 nm UV-C wavelength
• Manufactured to stable electrical and optical tolerances

How should I handle and install the LSE Lighting replacement bulb safely?

UV-C lamps require careful handling and protective measures during installation and servicing. Always power down the fixture, wear eye and skin protection, and follow the fixture manufacturer’s safety procedures to avoid exposure to UVC radiation and broken glass hazards.

• Turn off power and allow lamp to cool before touching
• Wear UV-rated eye protection and skin covering while servicing
• Dispose of broken or expired lamps per local regulations
