The Norman Lamps F15T8-BLB is a 15W T8 Black Light Blue fluorescent tube delivering UVA output centered at 365nm in a compact 18.0 in. length. The tube features a dark blue filter glass envelope that absorbs the majority of visible light while allowing long-wave ultraviolet radiation to pass through, producing the characteristic deep violet glow associated with blacklight applications. It seats into any standard G13 medium bi-pin fluorescent fixture and is rated for an average life of 7500 hours of dependable UV output.

The 365nm UVA peak emission makes this T8 fluorescent tube well suited for a wide range of professional and consumer applications.

The distinctive UV output also supports decorative and entertainment environments including nightclubs, theatrical productions, Halloween attractions, and art installations where fluorescent materials glow brightly against dark backgrounds.

Measuring 18.0 in. in length with a 1.00 in. tube diameter, the F15T8-BLB fits directly into compatible standard T8 fluorescent fixture housings. This T8 Black Light Blue fluorescent tube is sold as a single unit.
