Single-Ended Halogen light bulbs produce a bright white light making them ideal for use in task or general purpose lighting. These single-ended halogen bulbs offer long life lasting up to 2,000 hours. To help you find the right bulb for the right application, see Westinghouse's full offering of single-ended bulbs available in wattages ranging from 50 to 150 with either E11 (mini-candelabra) or D.C.Bayonet (double contact) bases. Single-ended bulbs are used in light pendants, table lamps, ceiling fans, and high-end decorative lighting. These bulbs should not be touched with bare hands. The oil from skin can create hot spots on the glass that reduce the life of the bulb.
