That's
0.005 Watt. So it will "flood" your cockpit with a lot less light than
your LED headlight.

This may be true but a laser straight out of the box is pretty
focused, and put a simple lens in front of it and you can keep the
beam even tighter. There may not be that many photons involved, but
they are all coming from the same direction, and that does count for
something. (somebody posted about a five digree divergence, the
lasers I've seen are all much tighter than that.)

I don't know whether it counts for the alleged problems, but there is
a nontrivial difference betweem laser light and the diode in your
headband.
