JD Lamps

JD lamps are single-ended halogen lamps used in fixtures designed for compact replacement bulbs. ADL Supply carries Halco and Hikari product families, including mini-candelabra E11 and double-contact bayonet styles. Start with the markings on your existing lamp: the JD designation alone does not identify a compatible replacement.

Choosing the correct JD replacement

• Base: Match the exact socket type. An E11 screw base and a BA15d double-contact bayonet base fit different lampholders.
• Voltage and wattage: Check the lamp rating and fixture requirements. Do not substitute a higher-wattage lamp or assume that every model uses the same supply voltage.
• Size and finish: Compare overall length, bulb diameter, and clear or frosted finish with the original lamp and available fixture space.
• Fixture requirements: Follow the fixture manufacturer's instructions for lamp type, operating position, enclosure, and dimming compatibility.

Browse Halco JD Lamps or Hikari JD Lamps to narrow your search. Confirm the specifications on the individual product page before ordering; products displayed together are not necessarily interchangeable.
