I had said that I would show my UV lamp to a few members, that were interested ... This lamp was made for detecting cracks in oilfield drill collar threads. So, the idea is that if your drilling a oil well, then we don’t want to break a collar at a thread at 10,000 ft down or so. That causes a fishing situation or whipstock around the broken collar. Depending on depth of course, the collars are used to push weight on a drill bit. At such depths, if not for having these collars, the drill pipe( As hard as it is to believe) will float. Thus causing the drilling to halt, to add more weight. Enough of that.
I have used this lamp in times past to inspect artifacts. Really I have no use for it as I don’t buy artifacts. Being of such power it will expose a fake or re-chip and even a later resharpening of flint artifacts. When warmed up( ( 15-20 minutes) it is 10K candlepower ....It is dangerous to the eyes. So much for that. The situation being that the older a artifact ( Or the ones I’ve used it on ) the more orange they glow. That said any recent chip of a artifact will shine, like silver.. Now, I’ve have in the past been sent artifacts and been asked to examine them with this lamp. I’m not going to get into what transpired but as the late H.W. Bush once said and I quote with parody ending “ Not gonna do it, Not going to do it, read my lips, no more inspections !” There were some very unhappy people, to say the least !
Anyway, a few photos.....JJ

Nice to have such a tool for the tough job of well drilling too - thanks for showing it!
