The Norman Lamps F32T8-BLB is a 32W T8 black light blue fluorescent tube that delivers ultraviolet UVA output at a peak wavelength of 365nm. Measuring 48 inches in length with a 1.00 inch diameter, this 4-foot linear fluorescent lamp is engineered for reliable, long-life UVA performance with an average rated life of 15,000 life hours.

The Black Light Blue (BLB) designation indicates that the fluorescent tube uses a deep blue-violet filter glass envelope, often referred to as Wood's glass, that absorbs most visible light above 400 nanometers and transmits primarily UV-A ultraviolet energy. This selective filtering produces the characteristic violet glow associated with blacklight applications while maximizing UVA output at the 365nm peak wavelength, causing fluorescent dyes, pigments, and whiteners in paints, inks, posters, and fabrics to glow vividly.

This T8 fluorescent tube is suited for a broad range of professional and commercial applications, including UV inspection and quality control, counterfeit currency and document verification, fluorescent dye and leak detection, forensic examination, theatrical stage and entertainment effects, nightclub and entertainment venue lighting, Halloween and themed displays, and illumination of fluorescent posters, artwork, and signage. The 360 degree beam spread provides even omnidirectional UVA coverage across the full length of the lamp, making it a dependable choice wherever consistent UVA reactivity is required.

The F32T8-BLB installs into any standard 4-foot T8 fluorescent fixture using its G13 medium bi-pin base and is compatible with standard T8 electronic ballasts. This non-dimmable fluorescent lamp ships as a single piece, with a full case quantity of 25 available for larger installations and ongoing maintenance programs.
