Wireless Emergency Lights Can Brighten Up Your Next Power Outage
Public places are equipped with emergency backup lights so that in the event of a power outage people can find their way to safety. So why shouldn't your home have that too? The ReadyBright system from Mr. Beams lets you easily install emergency backup lights all around home—which is probably a minefield of toys if you've got kids—that automatically power up when the power disappears.
The battery-powered lights—which come in versions for mounting on the ceiling or low to the ground—each run for about 40 hours thanks to low-energy LED bulbs. But the cornerstone of the system is a rechargeable flashlight/remote designed to stay plugged into an outlet all the time. It detects when the electricity goes out and automatically sends out a wireless signal telling all the backup lights in a 70-foot radius to turn on.
