Sure, you'll get some UV from that. The HID bulbs take a couple minutes to warm up though, so you might want to add a mechanical shutter if you expect exposure times to be short. You can buy dedicated UV bulbs (eg for sterilisation) with a different gas mix (mostly mercury) that will give you a much higher UV-to-visible ratio.

It will be UNBELIEVABLY bright though. I have a couple of 150W HID lamps in outdoor luminaires and they are incredible. You can't stand too near them and with the two, I comfortably lit a few hundred square metres at night. With 600W, you're not going to want to be in the same room as the bulb.
