LitezAll has completely re-imagined the light bulb and made it safer, battery powered, more versatile and fun to use. The PortaBulb® is the world's first grab & go® light bulb because it's actually a flashlight cleverly disguised as a light bulb. The PortaBulb® comes with a unique holder that easily mounts with either the included "3M" double sided adhesive or you may permanently mount it using 2 small screws (not included). This incredibly versatile light features 2 brightness settings, easily controlled by the convenient power switch. Use the LitezAll PortaBulb® hands-free in its base or simply pull it out and use it as a Grab & Go® flashlight. The base of the PortaBulb® is magnetic and sticks to most smooth metallic surfaces. For added versatility, it features a flip out loop for convenient hanging. This incredibly versatile light is battery powered and uses absolutely NO electricity. It's powered by 3 replaceable AAA batteries (included). The PortaBulb® is great under the sink, sheds, storage rooms, campers, tents, temporary night lights and during power outages. Please Note: 100% Battery Powered Does Not Fit Into Any Electrical Socket and Uses NO ELECTRICITY Patented.
