E-26 Medium Base HID 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).

HID stands for high-intensity discharge, which indicates that bulbs are brighter than standard headlights. Among the common types of HID lights are mercury vapor, low and high pressure sodium and metal halide lamps. Other less common variants include ceramic metal halide and xenon short-arc lamps. HID lamps produce light by sending an electrical charge or “arc” between two tungsten electrical conductors (electrodes) and through an ionized gas (also known as “plasma”) which is housed inside the bulb.
