If the production ones are like the betas, they look the same except the tip has a grey-colored coating.

I have a video showing one of the current and the betas in parallel being fired at the same time, as well as one comparing to an older Solar igniter. But the files are far too big to post here.

Have posted the latter video (in slow motion and in real time) to a similar thread on the other forum.
