Insta Bulb™ is the battery operated light bulb you can install without an electrician. Simply stick the base in anywhere you need instant light, slide in the light bulb, pull the cord and that's it. The bulbs are cool to the touch and shatterproof. Insta Bulb™ is great in attics, garages, basements, closets, and under stairs or cabinets. Each Insta Bulb™ requires four AA batteries (not included). Bulb slides out of base to become a handy lantern. 10 year warranty. Imported.
