Single ended halogen light bulbs produce a bright white light making them ideal for use in task or general purpose lighting. 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-can) or D.C.Bayonet (double contact) bases. These bulbs should not be touched with bare hands.
