How come no one sells kits to replace the filaments in incandescent

Is this a serious question?

You can't replace the filament because the glass is blown in place in/on
the base with the filament inside. You therefore can't remove the glass
from the base without fracturing it.

Incandescents cost about a quarter apiece before the environuts got
involved in lighting. No point in trying to repair something that cheap.

when I was a kid, I remember seeing a TV commercial about laser
beam incandescent lightbulb filament repair, but it was for very
large, very sports stadium bulbs. It may have been a General
Electric commercial, like the kind they air for their jet engines,
MRI machines -- you know, things that average families buy every day.

The solution would be to install a very small remote controlled welder
inside each incandescent light bulb. Then when the bulb burns out, the
owner could use his remote, turn on the welder, and weld the filament
back together, without ever having to open the glass enclosure. The
remote would need a joystick control, so the operator could position the
welding rods precisely at the filament break.

Robotic welding with a very small incision in the glass. You could blow
a fan over the opening, like they do at supermarket doors, so the vacuum
wouldn't leak out.

Or refill after welding with ArNe, which is a better gas than vacuum gas
anyhow.

Geeezzzzz, I thought you just needed to hold a vacuum cleaner hose by
the incision on the glass to get the vaccuum back in the bulb....

Wouldn't that suck the vacuum out? Then it would have no vacuum.

Thanks for the warning.

I was in fact going to do that but failed in my attempt
and I was going to try later. My system suffered a multiple chain reaction:


Seems the metal case on my vacuum cleaner shorted to ground
which in turn shorted the fuse out.
