One thought on “Halogen Lamp Types”

  1. I am looking for a halogen bulb for a reading/decorative lamp bought in San Fransico about 1992/92. The glasspart o the bulb iis about 35 mm fixed into a metal bayonet socket about 12mm dia. The lamp can be adjusted to two light streght. I suppose that the voltage is 120,I have used the lamp for several years in norway where the voltage is 220. I have used an archer appliance to reduce the voltage from 220 to 120. I have looke for a simila bulb her but have not foun any, can anyone help me with a type name? with a name it should be easy to order on internet i suppose, thank you Anders
