I know, smartass, they all glow in the dark. But these lightbulbs—a little old, I agree—are designed to glow even after the power goes out due to a TERRORIST ATTACK or if lightning maybe hits a transformer somewhere and the entire office is reduced to a mewling, screaming, frothing mass of writhing bodies.
Shatter-proof Glow-Lux Emergency Afterglow Lighting combines scotopic phosphor blend with non-radioactive after-glow phosphor blend to provide uninterrupted illumination in critical interior areas during low-light and no-power conditions. Even if bulb breaks, glass pieces will continue to glow up to 12 hr after power goes off. This 100% bomb-proof fluorescent lighting can also be detached and used as portable emergency light source.
Bomb-proof. This is the kind of adjectival usage to which we've been reduced. It's not "shiny," "pretty," or "nice to look at." This thing is bomb-proof.
