I've just had the dubious misfortune to catch this show, but one of the things that caught my eye was they appeared to have beams of coherent light in the set. Upon closer inspection it looked to be a very accurate iris on a moving head, but it was very bright, and divergence looked to be very good too.
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.
