The Norman Lamps F54T5/BL is a 54W High Output T5 black light fluorescent tube engineered to deliver ultraviolet radiation centered at 350nm. Housed in a slender T5 form factor measuring 45.8 inches in length and 0.63 inches in diameter, it fits standard G5 miniature bi-pin fixtures designed for high output T5 fluorescent systems. The lamp's specialized phosphor coating is formulated to emit UV-A energy in the near-ultraviolet spectrum rather than visible white light, making it distinctly different in purpose from standard fluorescent tubes.

As a black light (white) type fluorescent lamp, the F54T5/BL emits its ultraviolet output while maintaining a clear glass envelope, which distinguishes it from blacklight blue (BLB) tubes that use a dark cobalt-blue filter glass. This design allows the lamp to produce strong UV-A output suited for a broad range of professional and commercial applications. Common uses for 350nm UV fluorescent tubes include insect attraction and control in electronic fly traps and insect light trap fixtures, fluorescent material inspection, currency and document verification, forensic investigation, dye penetrant inspection for detecting surface defects, and various specialty industrial or scientific processes requiring near-UV illumination.

NLI exclusive manufactured product

The F54T5/BL carries a rated average life of 10,000 hours, making it appropriate for demanding continuous-use environments where reliable UV output is essential. This lamp is sold individually and is compatible with T5 High Output fluorescent ballasts and fixtures equipped with G5 miniature bi-pin sockets. Cross-reference model numbers for this lamp include F54W/T5/BL, FP54/BL, and F54T5/350BL, which may be useful when sourcing replacements for existing fixtures or verifying compatibility with other supplier SKUs.
