4W T5 Blacklight Blue Fluorescent Tube

Blacklight blue (BLB) fluorescent tubes use a dark blue filter glass that absorbs visible light and emits long-wave ultraviolet (UV-A) light. When powered on, they cast a faint violet glow while making white fabrics, fluorescent paints, and UV-reactive materials shine brightly.

Ideal for party's, stages, nightclubs, Bowling Center and Roller Rinks.

They can also be used for checking banknotes, stamps, security marks, forensic science, leakage detection, and material testing.
