Geeze that's a little bit over the top. In twenty years of using Profoto and 13 years of working with other pro photographers, I've never once seen or even heard of a flash tube exploding. Has anyone here using strobes ever seen a flash tube explode?
guess its too slow for people unless I sedate them first.
Apart from that, I'd be uncomfortable asking my models to look into bright UV light. A few seconds likely won't hurt, but from an ethical perspective, it doesn't feel right. I don't like contributing to someone's cateract.
Compared to the sun it's quite pleasant
I've had many decades of UV eye abuse and no cataract problems....yet.
No, not necessarily. While sun protection is also important, the difference between a UV source and the sun is that the pupil will contract in bright sunlight, protecting at least part of the eye from UV damage (so it won't protect against conjunctivitis / 'Klieg eye'). Since a UV source only emits a small fragment of its light in the visible spectrum, the pupil response is less pronounced, resulting in a much larger risk for e.g. retinal damage.
I had an aunt who smoked a pack a day and lived to the ripe age of 90...as with many things, you only know how much to appreciate it when it starts to fail. Moreover, like I said: it's not so much the photographer; they make a deliberate choice. It's the model and the ethics related to them.

Has anyone here using strobes ever seen a flash tube or modeling light explode? I mean if you throw cold water at it or knock the thing over that's different, but just explode all on its own? The great thing about tin type / wet plate is that you just need one pop every 10 minutes or so at most. And Halogen bulbs the same - never seen one blow. You can buy non UV coated covers for the profoto heads if you want a cover. I suspect the real reason why Profoto puts covers over the flash tubes is mostly to make a slightly softer and even light. I would not advise using your flash heads naked long-term, just saying it really made a difference for wet plate work.
Because flash tends to emit quite a bit of UV, which is very useful for collodion, and the short exposure makes it very suitable for portraiture.Collodion is sensitive to UV and visible blue spectrum. I wonder why people bother to use thousands of Ws flash lights if collodion will "see" only a fraction of it and flash itself is only 1/8000th of a second or so...
No you won't. Go on and try it. You'll be mightily disappointed. Wet plate sensitivity is pretty low to begin with, especially so in the visual spectrum, even on the blue side.blue LED light - like royal blue (450-465) + Ice blue (470-475nm) should be well enough for collodion and its not a UV so its safe to use. You could probably get away with 200-300W and time as long as 1/125s
?Sounds like a job opportunity for models that have already had cataract surgery.
