Good topic! I’ve always enjoyed 455 lamps since I first got into pinball. I have a collection of vintage GE 455 and Westinghouse 455 lamps, plus I have some of the very rare wedge type versions used in games like Al’s Garage Band and twilight zone, I believe they are 545?? Can’t remember.
I prefer the GE lamps the best, although the Westinghouse are really good as well and flash even faster. These both flash on/off very quickly and look awesome! I do not like the newer 455 as they flash way too slow, sometimes off for a few seconds. As an EM purist, the vintage 455 lamps are a must! I do not like the L.E.D. versions, just not the same.
