or maybe something else - let me know
Bulls eye lamp The wire ended bulb which appears to be rated at about 4.5V @ 300mA is made by Ediswan. It is soldered to two thin brass rods which pass through a copper parabolic reflector and are isulated from it by thin ebonite tubes. When first received some thirty years ago the reflector had been painted white but as this was flaking away I decided to remove it completely. I thought the reflector might have been nickel plated in the same way as the outer casing but I could find no evidence of this.
