These high quality solid brass electrified burners screw into oil lamp collars in the same way as an oil lamp burner does, without having to drill the lamps or otherwise alter the lamp's oil burning capabilities.
Simply unscrew the current oil burner and replace it with these electrified versions. This maintains the antique lamp's integrity.
Empty out all kerosene or lamp oil and clean with isopropyl alcohol. Allow ample time for the alcohol evaporate before putting on electrified burner.
