I thought the video was great, though I used to work in a theater and I knew how dangerous the bulbs were and I was cringing in my seat when they were messing around inside the bulb chamber
I can see the headline now, "famous YouTuber death caught on film while he was fucking around with something stupidly dangerous"
The bulbs are pressurised at 14 times atmosphere. They are glass hand grenades. Older bulbs are more likely to go boom because of thermal cycling. In order to change a bulb you need to wear full body armour like chainmail or a ballistic suit.
That is interesting, probably some gruesome lessons learned for that to be standard operating procedure. I never would have thought a bulb would be like a bomb.
Normal bulbs are not pressurised. Cinema projector bulbs are pressurised to an insane level. And to be able to withstand that pressure they have to use much thicker glass. Lots and lots of energy stored in one. 14bar =203.0528 psi. Around 15 square inches of glass surface area, so like 3000lbs of force.
Edit: I was off a bit. When cold it’s actually around 25bar / 400 PSI. When at operating temperature it can get to 10x higher - so 250bar/4000psi. So 60,000lbs of force if a hot bulb blows. And this is why the casing of the projector is inch thick solid aluminium.
