As per Allee’s request, here is a closer view of my Aerolux (I presume) electric candle lamp with matching base that I scored at an antique store in New Hampshire a few years back. I was amazed that the bulb had lasted, and with its original Syroco composite wood base! This is the tallest candle bulb I have seen, and have never seen this particular model before. The flame does not flicker, but continually glows with a gorgeous deep electric purple glow around the edge of the flame.  Eternal!
