The light bulb that can’t go out

Ever needed a bulb that you needed to stay turned on 24 hours a day, even if the power went out? Neither have I, but I can envision some scenarios where that might be important. A dark corridor connecting subway platforms, perhaps? The good news: Feit’s latest LED bulb offers a potential solution. The name really says it all: The Feit IntelliBulb Battery Backup is outfit with a built-in lithium-ion battery that powers the bulb, kicking in automatically if the power goes out. The bulb can still be turned on and off at the switch, but in the event of a sudden power cut (or a tripped circuit breaker), the light briefly shuts off, then springs back into life within a few seconds
