Here's a NOS pack of Westinghouse 100W Turtle-Lite incandescent lamps.Pretty cool packaging,unfortunately when I tried one of the lamps to measure the current and it burned out after 2 seconds instead of 2500 hours. :( These were made in either 1977 or 1978 as the coupon that is included expired on Dec. 31,1978
Thanks! No, I didn't try the other one yet,just in case it burns out too. It was a sales gimmick as they were supposed to be slower burning lamps and guaranteed to keep on going for 2 years.
Ahh i don't think they's both burn out though. I think it was just a dud. Ahh I get it; turtles are slow lol. I guess they should have stuck a cheetah on the lamp you tested.
Nice! Too bad one of them burned out during testing though. I suppose you could try lighting the other one in series or with a variac if you want to test it.
ahh I never thought about testing lamps in series. If you have a dimmer switched light that would do the same thing too, set the dimmer low and then screw in the lamp. The lower voltage wouldn't kill the lamp.
Yeah they must have thrown in a cheetah version. @ Joe and GEsoftwhite100watts, yes I will have to make up a couple sockets in series for testing,yes Mike a dimmer would be good too for a "soft start".
The one that failed had vacuum loss, very likely there is a crack somewhere. In my experience with Westinghouse bulbs, the most common area for cracks to appear would be on the stem just below the stem press. But it is possible for other areas as well.
