The big innovation of the NAO light is that it is supposed
to sense the environment and automatically adjust the light output to
match. <http://www.petzl.com/us/outdoor/headlamps/nao> So, for
example, if you're in a large passage looking around it will be on
high, but if you then look down at your survey book to sketch, it
will dim so that you're not blinded by the reflected light. Sounds
good in principle, but I suspect there will be situations where the
light will not adjust the way you want it to. Sounds like a case of
trying to design something to be too smart. What's wrong with
manually changing the output as you need to?

In July Petzl will have a new LED out, the NAO, $175, 7 to 355
Lumens, rechargeable Lithium-ion or two AAA in a pinch. That's all I
know for now. Info from Climbing magazine. It may give Sten a run
for it's money.
