The Bulbrite 460325 decorative chandelier light bulb was developed for high-end chandeliers to show crystals and precious metals at their best. Krypton gas filled lamps create a brighter and crisper sparkling white light by eliminating much of the yellow spectrum that causes dullness of light. This Bulbrite gas lamp has a CA10 bulb shape and a candelabra (E12) base.
