Smashed General Electric Inside Powder Coated Ceramic Christmas Light Bulb

Here I have already burned out bulb and decided to break open the inside envelope of powder coated ceramic Christmas light bulb. Lo, and behold, indeed it has inside powder coated and it does comes off easily when it scratched.

By the way, there is '4' at the pressed stem area here at the facing exhaust tube.

I did an experiment last night with a GE glazed ceramic bulb with a hole in the glass. The filament was still intact, so I put a piece of tape over the hole to see if the filament would stay lit. Well, it lit for a second then smoked inside. The exeriment proves that once the vacuum is gone out of the bulb and air gets into it, the filament will burn out for sure.

I have some of these, most with brass bases and a couple with aluminum.
C7s with inside coating seem kinda rare.

My very first word was LIGHT!

That's why lamps have either a vacuum or an inert gas in them.
