This is probably a long shot... but has anyone here had any experience with an LTM Blue Torch 270 "sun gun" HMI unit?
Unit works off DC... probably from a battery source back then. Little info available. I believe it requires 24 volts to make it work.
Interesting unit. Has a thumb wheel on the side that moves the lamp in and out to vary beam spread. No need for lenses. Head about the size of a Joker 200. Same for the ballast.
