JD Type halogen light bulbs are tubular shaped and run on line voltage (120-130 volts). These halogen light bulbs are used in light pendants, table lamps, ceiling fans, and high-end decorative lighting. JD type halogen light bulbs have double contact bases (called DC or BA15d), mini-candelabra bases (E11), or European bases (E14)(base chart). JD type halogen light bulbs are available with both clear and frosted glass.
Please note that JD type halogen light bulbs should not be touched with bare skin. Halogen light bulbs utilize a semi-permeable glass with can be penetrated by oil from skin. The oil creates hot spots on the glass that reduces the bulb's life.
