Bulb For An Emergency!

Bulb For An Emergency!

From our trusted friends at Farpoint®, this LED light bulb works like a regular bulb, but also turns on when the power goes out. Can even be used as a flashlight when you screw it into the included tail cap, which has a hook so you can hang it where you need it. Bulb is 1000-lumen and 10W with a 4000K color temp (soft white). As an emergency light, throws 200-lumens with a 3-hour run time. You’ll get a set of (2) bulbs per order.

Jarvis' tech info: The power outage function activates when there is a power cut to the hot and neutral wires which are connected through the circuit breaker to the transformer on a pole outside your house. It "sees" that there is no voltage and the wires are effectively shorted together by the low resistance of the transformer winding. Hence the light turns on when there is no power and not when you flip the light switch. Thanks to Art, a long-time customer for the explaination.
