User Review: Petzl MYO RXP

Fantastic headlamp. I bought it for the following features:

+ it's regulated (meaning you will always have the same illumination level, even if the batteries slowly discharge in time)

+ bright LED (powerful light) with boost

+ programmable levels

+ compatible with Lithium batteries (superior performance in cold weather)

- cost for all this: it's heavier than other headlamps

I use it for mountaineering.
