Gadget of the Week – SmartCharge LED Lightbulbs
Published on February 9, 2015
Power out? Not a problem if your house has a few SmartCharge LED bulbs! These nifty lightbulbs know whether or not someone has just turned off the switch, or if there has been a power failure. If it is the latter, the bulb will then provide users with 4 hour of continuous light, thanks to an integrated 2200 mAh Li-ion battery.
When the power becomes restored, the unit's battery is able to recharge itself from empty to capacity in about 6 hours. This bulb has a rated life of up to 40,000 hours, but it may need replacing every 3-4 years depending on use.
These bulbs fit standard fixtures. A single bulb comes in at $35, two for $55, and a 4-pack for $100.
