Holophane 175 watt metal halide fixture hot restrike part 1

This is a hazardous locations fixture made by Holophane. It makes the coolest noises. It can run both probe start metal halide and mercury vapor lamps. It also has a quartz halogen lightbulb that turns on whenever the metal halide lamp isn't working, such as during a hot restrike or when it is burned out and needs to be replaced, and probably when the metal halide lamps is simply just unscrewed. Since the glass is currently a bit stuck I haven't been able to test that. Here we are starting with the fixture at full brightness and then we are going to do a hot restrike. This is the first video in which you see the quartz halogen in action. The lamp doesn't restrike in this video but I have another one where it does. None the less, enjoy.
