The Norman Lamps F32T8-BLB is a 32W T8 Black Light Blue fluorescent tube delivering ultraviolet UVA output at a peak wavelength of 365nm. Measuring 48 inches in length and 1.00 inch in 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 designation indicates that the lamp uses a deep blue-violet glass envelope to filter out most visible light, transmitting 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.

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, theatrical stage and entertainment effects, nightclub and entertainment venue lighting, and illumination of fluorescent posters, artwork, and displays. The lamp causes fluorescent materials in clothing, paint, and other surfaces to glow brightly, making it a reliable choice wherever UVA reactivity is required.

The F32T8-BLB installs into any standard T8 fluorescent fixture with a G13 medium bi-pin base and is compatible with electronic T8 ballasts operating across a standard voltage range. An LED alternative is also available under order number LED-T812-48-BLB for applications where an energy-saving upgrade is preferred.
