Ushio 1000969 100W Halogen Bulb

The Ushio 1000969 is a 100 watt halogen bulb designed for fixtures that accept a BA15D bayonet base and operate on 120 volt circuits. It produces a warm 2800K colour temperature suitable for general indoor lighting where a traditional halogen spectrum is preferred. Rated life is 2000 hours under normal switching cycles. This lamp is intended for residential or light commercial sockets that match its electrical and mechanical specification.

Installation notes and common issues

Switch off power and allow any hot lamp to cool before handling the glass envelope with bare fingers. Oils from skin create hot spots that shorten the 2000 hour rating and can cause premature failure. Align the bayonet pins with the socket slots, push gently and twist until the lamp seats firmly; forcing the base can crack the glass or bend the contacts. Verify the fixture is rated for 100 watts and 120 volts to avoid overheating the wiring or socket.

Compatibility checks before ordering

Confirm the existing socket is a BA15D double-contact bayonet type and not a screw or single-contact variant. Check that the fixture’s maximum wattage label permits at least 100 watts and that the supply voltage is 120 volts. Ensure the physical length and bulb diameter fit within the shade or enclosure without touching surrounding surfaces. Buyers who need a different base, voltage, wattage or longer rated life should select an alternative lamp.
