"He who marches out of step hears another drum." ~ Ken Kesey
Richmond Solarbeam 10K metal halide, awesomest of them all. Well, in terms of pure UV light output, doubt anyone is shooting more than a 10K watt bulb. Built in light integrator and 30 preset exposure lenths. I'm sure other manufacturers have those features and a 10K watt bulb, but I don't know any off the top of my head.I know Olec and Nuarc make some good damn exposure units, but my knowledge of exposure units is very limited. I just don't have as much fun studying the latest exposure unit technology and features like I do automatics.
