Electric Oil Lamp Converter offers a simple solution for adapting oil lamps to electric. In addition, this handy part eliminates using a glass chimney, as a harp is now used to support the lamp shade. Use on oil lamps with a #2 collar which have a 1-3/16" interior diameter. No wiring is necessary. The quality and ease of use make this part a great option when restoring vintage and antique oil lamps.
