Sandy this must be a prototype. Amergraph specs on their V28-VMS Metal Halide 1200 watt table top imaging system makes the same claim. " Speed: Instant Start 1200 Watt Multi-Spectrum Metal Halide with patented circuitry, exposes plates and proofing materials 3 to5 times faster than comparable Mercury Vapor Units and does not require cool-down between exposeures." I was considering their V28-VMS unit until I read your post. Now I think I'll hold off and contact Amergraph and find out about this new unit.
