Incandescent alternative to halogen lamps. Krypton xenon low voltage light bulbs have long life, crisp white light and are perfect for general illumination or accent lighting purposes. These single-ended halogen bulbs offer long life lasting up to 1300 hours. 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.
