Krypton/Xenon E-26 Bulbs
E-26 Standard Base Krypton/Xenon 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).
A krypton xenon bulb contains a mixture of both xenon and krypton gases. When electricity is passed through a filament that is similar to that used in an ordinary incandescent bulb, it heats up and produces a brilliant white light.
