Halogen E-26 Bulbs
E-26 Standard Base Halogen Light Bulbs
The term E26 refers to a light bulb's cap or base - the bulb component that allows for both electrical and mechanical contact. The letter "E" in E26 refers to Edison Screw, the most standard of lamp bases, while the numerical "26" refers to its diameter in millimeters (approximately 1 inch).
Halogen is a type of lighting technology that is essentially an enhanced version of incandescent. Just like with incandescent light bulbs, the electrical current enters the socket and travels up to the tungsten filament, heating up the filament to incandescence. Halogen light bulbs have tungsten filaments housed in a quartz capsule and filled with iodine and bromine gases. Halogen lamps can also operate at a higher temperature than incandescent lamps. This is why you often see small halogen quartz light bulbs with a 250-300 wattage rating.
