Restrike in 3... 2... 1..

Looking at the arc tube of an Osram 400w NAV-T Super 4Y lamp a couple of seconds before restriking after a power interruption.
It starts just before the midpoint of the arc tube and then slowly makes its way down the starting aid on the arc tube wall towards the other end until you start getting the streamers breaking out which means it's just about to restrike!

I have got a 100w lucalox that does this, it is like little lightening strikes all the way along the tube.

I've an Osram NAV-TS 70W Super 4Y that does this, but without lightning, only illuminated strip.

It certainly is fun to watch!

I remember watching a metal halide trying to restrike in a petrol station when I was much younger. I referred to them as plasma ball lights after that since the effect it was producing during the restrike phase looked so similar to a plasma ball Laughing

Just another awesome memory that LED would never ever replicate

In my tracklight, the Osram NAV-TS 70W Super 4Y Slovakia initially have a dim lighted strip at the starting antenna, which getting stronger and stronger, until it restrikes.
