Incandescent alternative to halogen lamps. Xenon low voltage light bulbs have long life, crisp white light and are perfect for general illumination or accent lighting purposes available in a variety of shapes, styles and wattages. To help you find the right bulb for the right application, see Westinghouse's full offering of JCD bulbs available in wattages ranging from 20 to 100 and have either GY6.35, GY7.9/8.0, G8, or G9 bases. G9 base JCD type halogen light bulbs have two loops on the base instead of straight pins. JCD type halogen light bulbs are line voltage (120 to 130 V) bulbs that can be used in puck lights, under-cabinet lights, desk lamps, display lighting, accent and landscape 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.
