An Electric Light Globe Heats a Wire to Extensive Illumination. An electric light globe heats a wire filament up to high temperatures that ignite bright visible light - a natural consequence of incandescence. The delicate wire is safely encased within a tough glass bulb protected by an inert gas or a vacuum seal that inhibits oxidation reactions from occurring. Within certain special lamps, a chemical reaction significantly prolongs the lifespan of the delicate filament through controlled metal redeposition. A simple feed-through system supplies electricity to the bulb via terminals embedded inside the protective glass case. These light-emitting units typically utilize a universal socket providing both necessary physical support and electrical connection. A huge range of bulb dimensions exists from one-fifth of a volt all the way up to nearly three hundred volts, reflecting variations in brightness as well as specific operational needs. Due to affordable construction and simple direct current adaptability without any additional external regulation tools needed for effective operation on AC/DC sources alike; this extremely versatile lighting choice shines throughout homes & offices around the world today - widely used not only in domestic lighting setups, hand held lamps for convenience at home or on the go within automotive lights (headlights & taillights) flashlights that provide both personal as well as external use through the creative lighting displays intended purely visually engaging promotional advertising campaigns worldwide daily.
