I've always wondered how they make those curved arc tubes

It'll be all right in the end, and if it isn't all right, it isn't the end Love

Probably form during heating the arc tube before evacuating/filling

Pretty, please no more Chinese failure.

Your lamp is like to my lamp excluding a small element near the base. What is this?
And what is the function of the narrow metal ribbon?

You're probably seeing the starting resistor. As to the ribbon, there is usually code numbers, or the date code is on it. I put this lamp in storage...I'll try to find it and see what it says. There's also a thermal cutout attached to the starting probe that prevents the lamp from restriking when hot that contains a small wire...are you looking at that?

A man has two lives to live, and the second one begins when he realizes he only has one.

Better to remain silent and be thought a fool than to speak and to remove all doubt.

I said about an element above resistor. Small orb welded to the upper wire.
Thank You, probably it's him. In my lamp there is no this element -- it's an early model?

I took this picture a while ago...I think it's another resistor...I'll have to look at the lamp again.
