GE Mazda C-7 Green Christmas Bulb

GE Mazda C-7 Green Christmas Bulb


The oldest christmas light bulb that I have. Think this is 1930's era and the Mazda label was done away with by 1945. Love the old matte painted finishes with small scratches. Back in this era this is when GE used the ' G - E' instead of their famous 'curly' or 'meatball' logo.

The first General Electric C7 Christmas light bulbs were introduced in 1934, and yes the 'Mazda' branded was discontinued around 1945. I have two in my collection so far

Pretty, please no more Chinese failure.

You got the yellow version . I only have both blue and green in my collection.

Now we need to find someone in this site to see if they have the red version in their collection

Pretty, please no more Chinese failure.

Very nice!! I have a bunch of these in all of the colors; they have a really cool effect when lit, especially the cobalt blue ones! I see you have the diamond etch on these bulbs too!

Those early C7 Christmas light bulbs are usually hot. I have measured one of them and spit out about 8 Watts.

Pretty, please no more Chinese failure.

Aww

If you can scrape the EOL bulb, you can find the date stamp at the stem inside the bulb

Pretty, please no more Chinese failure.

@ rjluna2 , your' right these bulbs do indeed get very hot! And I always thought the blues and the greens were the worst ones when they generate heat.

Long live the great old 20th century quality in electrical & lighting products!
