WebNov 11, 2024 · "AC 100-240V" means it has a universal supply inside, can handle AC power anywhere in the world. But you gotta give it at least 100V (AC or DC) to have any hope of it lighting up correctly. THis also means that you're not going to be able to control the brightness by controlling the applied voltage. Incandescent bulbs are manufactured in a wide range of sizes, light output, and voltage ratings, from 1.5 volts to about 300 volts. They require no external regulating equipment, have low manufacturing costs, and work equally well on either alternating current or direct current. See more An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. The filament is enclosed in a glass bulb with a vacuum or inert gas to protect the filament … See more More than 95% of the power consumed by a typical incandescent light bulb is converted into heat rather than visible light.
