The Norman Lamps F30T8-BLB is a 30W T8 Black Light Blue fluorescent tube measuring 36.0 inches in length and 1.00 inch in diameter, fitted with a G13 medium bi-pin base for direct installation into standard T8 fluorescent fixtures. This lamp produces UVA radiation centered at 365nm, delivered through a specialized blue-filter glass envelope that blocks most visible light while allowing ultraviolet wavelengths to pass through, creating the characteristic deep blue-purple glow associated with black light blue fluorescent sources.

The BLB designation identifies this T8 fluorescent tube as a filtered blacklight design, distinguishing it from unfiltered BL types. The dark blue glass coating suppresses visible light output and directs energy into the UVA spectrum, which is essential for applications requiring a high ratio of UV energy to visible light. This makes the lamp well suited for causing fluorescent materials, dyes, and coatings to glow visibly against darkened backgrounds.

This T8 fluorescent black light blue lamp serves a wide range of professional and commercial applications. Industrial and commercial uses include fluorescent dye penetrant inspection for detecting surface cracks and defects, currency and document verification, forensic investigation, gemstone and mineral examination, and quality control processes that rely on UV-reactive materials. Decorative and entertainment applications include nightclub and theatrical effects, art installations, and any environment where the distinctive fluorescent glow effect is desired. The lamp is also used in insect control traps designed to attract flying insects with UVA wavelengths in the 350-370nm range.

Rated for an average life of 7500 hours, this 30W T8 black light blue fluorescent tube installs into any fixture with a compatible G13 bi-pin socket. It is sold as a single piece with a minimum case order of 25 units.
