40W BLB Replacement Bulb - G10Q-4 Base Fluorescent

This 40-watt U-shaped blacklight blue fluorescent bulb delivers concentrated UV-A output in a compact U-bend form factor. Built with a G10Q-4 (4-pin) base, it fits U-bend 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.
