SPECIFICATIONS: Included in this purchase is a single krypton/xenon mini candelabra bulb with a standard E11 screw base. Each bulb is 20 watts and has a frosted finish, which diffuses the light. Each bulb is ‎‎2 x 1 x 1 inches. Krypton/Xenon gas creates a long life, bright white light source. XENON KRYPTON LIGHT: Same bright white light as a halogen using pure xenon gas from Japan. Xenon and Krypton gas is considered the original halogen alternative. They can produce more lumens and brightness with less wattage than incandescent and halogen bulbs. Fully dimmable without performance loss. UV SAFE: Halogen bulbs are known to emit harmful UVA and UVB rays. These tiny bulbs have a full UV stop, meaning you won't have to worry about the effects of UV light when in use. As such, these bulbs are also perfectly safe to use indoors and in any commercial or residential setting. Clear FINISH: These bulbs are clear glass but available in a variety of wattages and finishes. A clear glass globe emits light directly. A frost finish diffuses the light for a softer lighting effect. Frost bulbs are ideal as a decorative alternative where high intensity light is not desired. LONG LASTING: These Krypton/ Xenon bulbs are extremely energy efficient and have a long-estimated lifespan of 3,000 hours each. That means fewer burnouts and replacements over the course of the life of your fixture. A great upgrade for your home's existing fixtures.
