Title: Edison lamp
Post by: sec on June 30, 2006, 11:50:46 am
I just acquired a ruby glass, carbon filament lamp with the normal black insulator base. It has no marks on the bulb but there is an oval sticker printed: "EDISON" with the watts (64) and volts (125) written in ink. I have searched for a similar marked example to date it but no luck. Does anyone know when this sticker was used? I have attached some photographs. It is a very dark red and was in use on a front porch. Thanks for your help.

Hi sec, welcome to the forum.? Thanks for sharing the pictures - nice old bulb you have there.? As far as I know, GE/Edison used oval labels from around 1901 to about 1905.? The label on your bulb looks a little different than what I have normally seen.? The more common oval Edison label can be viewed on this particular bulb shown at the link below:

As you will notice, both labels are oval in shape but differ slightly.? I would guess the age to be the same though.? I hope this helps a bit!

Tim, thanks for the information. I guessed it dated about 1901 but just wanted to get confirmation on that. Why do you think the label has watts instead of candlepower? Isn't that unusual for the date?

The term "watts" was printed on the labels of American made light bulbs beginning around 1910.  Perhaps this is a better clue to your bulb's exact age as opposed to the shape of the label.  Sorry I can't narrow the date further - perhaps someone else reading this can provide a more specific time frame.
