20W Fluorescent BLB 24 Inch - G13 Base

This 20-watt blacklight blue T12 linear fluorescent tube delivers ultraviolet light optimized for insect attraction and UV-reactive applications. Built with a G13 medium bi-pin base, it fits compatible fluorescent fixtures and is ideal for bug zappers, UV displays, and entertainment lighting. The deep blue glass envelope blocks visible wavelengths while emitting UV-A radiation in the 350-400nm spectrum, producing a distinctive ultraviolet glow.

The filtered blue envelope maximizes UV-A output while blocking visible light, creating a pure ultraviolet effect that activates fluorescent materials and attracts flying insects.
