it was quite a bright moon and i found it worked a lot better when there was complete darkness i.e. in wooded areas.
one thing that is importent to get right, the angle of the light. If you set it to look down right in front of you, and its cold, as it was last night, your breath is caught in the light, momentarly blinding you.
you have to angle it so that it light edge is about 1 meter in front of you. If its any further away its too diffused.
I spoke to a person whom has had the previous two generations, including the `plus'. He said, "the XP is in a league of its own". There is three brightness settings and the highest will give light up to 35 meters away. There is also a filter for map reading (so you dont kill you night vision from the glare.
Anyway, if you can hold out, i'll let you know how i get on.
I run x-country most of the time and its black as the ace-of-spades at the moment.
