Double-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 double-ended bulbs available in wattages ranging from 75 to 1500 with RSC (recessed single contact) or Metal Fin bases. 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.
