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 2000 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.
