Anyone else seen this, or come across the fixture before?
Also, given how bright it appeared (And all the talk of safety that goes on) I'd be curious to see exactly how much they measured on a meter. If a regular fixture can go over MPE, it raises interesting questions about eye safety at a gig generally.
I assure you that typical moving lights can exceed the MPE for ocular hazard...however, there are no regulations which limit exposure. This issue has been raised since the early 80's and has never been resolved. There was a demonstration at a LDI once where a vendor would make the back of his clipboard smoke to show "how powerful it was". HAHA sometimes you just have to shake your head at ignorance level of some folks.
