Almost always, Bowens studio flash units with non-coated Bowens tubes, with any filters. Except landscape subjects, of course.

 

Enrico, Any ideas on how the Bowens flash might compare to the Cannon 199A flash as far as UV depth/content?

I missed this post since at the time I was flying to the US, now catching up.

 

I have no idea about the Canon flash, but I recently posted in another thread the emission spectrum of a Bowens with uncoated tube (a standard non-coated tube as sold by Bowens and unmodified thereafter, not a coated tube that had its coating removed post-sales). I also computed the amount of UV in its emission, based on emission level (not power) between 180 and 1,200 nm as measured by my spectroscope at intervals of about 0.3 nm: slightly more than 20% of the total emission is in the UV, i.e. at wavelengths lower than 400 nm.
