Title: Help Ageing My Bulbs?
Post by: PinkFloydEffect on September 19, 2011, 09:23:15 pm
I dug these two bulbs up behind our house as a kid (I'm 21 so a decade ago).

One I would assume is older than the other because of the pointy tip from hand blowing? I would love to be able to know the range of years they could have been made during...

The rusty socket old one says Westinghouse, with what appears to be a a hand written 3/5 or 3,5

Then these is this bulb I found in a working socket where I work; a turn of the century New England chair factory. It was in the "way back" section of a storage area that has not been in use for a long time, when I turned on the lights it stuck right out like a sore thumb among all the frosted bulbs! I immediately turned off the lights and unscrewed the sucker, put her in my lunch box  :-D

When do you think it was made? It said Philips but it washed off when I cleaned the bulb with Windex. I believe it is a 150W?

Those first two bulbs I would presume to be pre-depression.  The tip is for vaccuming out the air, not from handblowing.  Are these lamps carbon or tungsten filaments?

That last lamp is new.  I have a few like that.

I have no idea what kind of filament they are, one does not have the tip but could have been made during the same time period? Newer technology during a transition period?
