I've seen this question knocked around many times. I decided to write to a couple lighting companies and have an Electrical Engineer from each of them answer the question for me.
So far, only Sylvania has answered, but that answer is pretty much to the point when considering 24/7 lighting for your grow. Your light health will take 15 minutes a week:
"Thank you for contacting us about SYLVANIA products. Your questions, feedback, and opinions concerning our products are important to us. If you are operating a HID light continuously it needs to be turned off once a week for at least 15 minutes to allow the arc tube time to cool down and "rest". Once a day is not necessary but it should be depowered at least once a week."
I also contacted Lumatek. If and when they reply, I'll post their reply here in this thread also.
