Thanks. So that 30W lamp in another comment might be a safty hazzard if someone in close range stares at it and the beam is tightly focused.

  The beam is not going to be tightly focused, if it needs to cover a big chunk of a stadium at once

  I guess this device can be modified to take visible red lights with some redesign, if you'll be really concerned with that.

  You're right. While we're at it, we should make sure no one goes up to the massive speaker system and puts their ear right up to the speaker cone too.

  Yes. The manual from the manufacturer recommends wearing specific green tinted safety glasses if you are standing closer than a meter to their transmitter while it is on.
