Indeed it is something you dont often see. I always thought it rather unfortunate that nobody offered 3-Way Clear lamps, and shortly after starting work at GE's Labs asked if the plant would make up a couple of specials This design was quite new at the time, employing only three lead wires instead of the usual four. It brought with it quite a cost saving for the factory and I believe is still the most efficient, and lowest cost 3-Way lamp on the market.

Remember these. I may even have one in the archives somewhere, a Philips argenta-coated "Drielicht" which I believe was 40-60-100w. If I can get hold of it I'll put it into my incandescent album for you guys. Think they also made a 60-100-160w.

The Americans always did like 3-way lamps, every US hotel room I've ever stayed in right up until about 5 years ago had them. Unusual to see a clear one, though
