However, some time ago a Cree distributor showed me one of their LED in
action, and before lighting it he warned me not to look directly at it. And
he was right, these LED produce a light that you can't stand, even from
several meters.

....which is the reason why your eyelid reflex will protect your eye from
damage.

Really, I think a lot of "Don't look directly into this LED flashlight"
crap is just marketing hype. Q: What is brighter than a super-bright
flashlight? A: A dangerously bright flashlight.
