Sounds to me you are using your light as a weapon and although it is in fun I cannot really go along with misusing high powered lights however innocent your intentions are.
I have to concur with mcnair55.
MightyBright, I see you're a new member here, and we're happy to have you, but on the whole, I think it's fair to say that we tend to discourage the use of flashlights for temporarily "blinding/disorienting"
unsuspecting people "for fun" (as opposed to informing them before the game begins that you will be temporarily blinding them during play).
We've also had folks say they wanted to use their bright new lights as a way to deal with loud talking people in movie theaters, etc., These are
NOT good uses for your flashlight.
These new high powered LED lights need to be treated with respect, and yes, they really can cause serious eye damage if used improperly.
Of course many lights include a disorienting strobe, often advertised as a way to fend of attackers, and we've had many threads discussing the real-world merits of these functions, but that's not what you're talking about.
I would simply ask you to think about what you are considering doing to your friends before you do it.
P.S. It's quite possible I'm just being an old fuddy duddy, and if so, I apologize. I also recommend not running with scissors
