Abstract
A lamp or light tube that is both shatterproof and produces an after-glow effect. The light tube is comprised of a cylinder sealed by glass and metal end caps on each end of the glass-sealed cylinder, and electrical conducting pins extend from at least one of the metal end caps to connect the light tube to a power source. The glass-sealed cylinder is coated on its exterior with a shatterproof coating composition that emits an after-glow effect. The coating composition is comprised of a strontium aluminate after-glow phosphor, an ethylene acid copolymer resin, and an ultraviolet additive.
