Ascella is the LED light bulb of the future. Saves energy, works as a portable flashlight, and turns on automatically during a power outage, thanks to its smart sensing technology and lithium ion battery backup. Ascella draws only 5 watts of electricity and fits any standard screw base light fixture. Lasts 20,000 hours (about 18 years), using about 60 cents worth of electricity yearly. Ascella's cool-to-the-touch base extends to make a flashlight for easy use during power outages. Ascella is the first and only smart light bulb.
