this seems more like stage and club special lighting and not the unfiltered blacklight we use for developing.

The unfiltered black light fluorescent bulbs with a high output UV rating is the better choice for our applications.

There are a few mentions of "higher" uv output than standard black lights. I think I saw nanometer graph somewhere on the site.
When you dig grave will you make it shallow so that I can feel the rain?

The histogram is the important stat that determines if the wavelengths and amplitude of the light is sufficient to expose a screen.  The show lights would have to be engineered to avoid causing injuryto the eye.  But a 5K MH is strong enough to damage your eyes and should never be looked at.  If it is safe UV light it probably won't completely expose the emulsion, you may get an image, but not an exposure.  Too often the rush to shoot faster/cheaper has made us poor screen makers.  Bake the cake, no baker decides that under cooking a cake so he can do it faster is the way to go.  Looks like a cake but it is gooey on the inside, same with emulsion.  Either cook it completely with good light, or it won't perform as advertised.
