GE 10531 - F40BLB

This is not an LED lamp; it is a Black Light Blue 40-watt T12 four-foot fluorescent tube with two male G13 medium bi-pin bases—one at each end. Ideal for parties, Halloween setups, and themed environments, this lamp features a special internal coating that filters out most visible light, allowing white and fluorescent colors to glow with a haunting, ultraviolet effect.

It’s important to understand that “Black Light Blue” refers to a specific type of UV-A emitting light, distinct from a true “Black light” (UV-C). While UV-C lamps are used industrially for sterilization and adhesive curing—and can be harmful to skin and eyes—Black Light Blue lamps like this one are designed for safe visual effects and ambiance. This lamp is intended for use in T12 fluorescent fixtures and requires a compatible ballast for operation.
