The Norman Lamps F20T12/350BL/TF is a 20W T12 fluorescent blacklight tube engineered to emit ultraviolet energy at a 350 nanometer peak wavelength. This linear fluorescent lamp measures 24.0 inches in length with a 1.50 inch diameter, making it a direct drop-in replacement for standard T12 fluorescent fixtures using a G13 medium bi-pin base.

The T12 fluorescent tube features a white glass envelope with a specialized phosphor coating that transmits UV-A output while allowing visible violet light to pass, distinguishing it from black light blue types that use a dark filter glass. Its 350nm UV-A emission makes it effective for a broad range of applications including insect control fixtures such as bug zappers and fly traps, UV fluorescence inspection, counterfeit currency detection, mineral and gemstone identification, forensic examination, screen printing plate exposure, and decorative or theatrical lighting effects.

This fluorescent tube is finished with Norman Lamps' proprietary Tuff-Coat shatter-resistant coating, a UL-approved process that encapsulates the glass envelope in a transparent polymer film. The coating contains glass fragments if the tube is ever broken, reducing the risk of glass contamination and supporting safety compliance in food processing facilities, restaurants, food storage areas, and other environments where glass breakage poses a serious hazard. The Tuff-Coat finish does not reduce UV-A light transmission or alter the lamp's output characteristics. Rated for 6,000 average life hours, this T12 fluorescent blacklight tube serves as a direct replacement for the F20T12/350BL and F20T12-BL.

• 20W T12 fluorescent blacklight tube, 24.0 in. length, 1.50 in. diameter with G13 medium bi-pin base for standard T12 fixture compatibility
• 350nm UV-A peak emission attracts flying insects for use in bug zappers and fly traps; also suited for UV inspection, forensics, currency detection, and decorative lighting
• White glass envelope with UV-A phosphor coating transmits blacklight output while allowing visible violet light to pass — distinct from black light blue filter-glass types
• Tuff-Coat shatter-resistant coating encapsulates the glass envelope in a transparent polymer film, containing fragments if broken and supporting glass-safety compliance in food service and processing environments
• Rated 6,000 average life hours; direct replacement for F20T12/350BL and F20T12-BL in compatible T12 fluorescent fixtures
