I purchased one of the original DUOs several years ago. I originally
purchased my first headlamp to get me in and out of the woods while
hunting. I would use it for an hour in the morning and an hour in
the evening. I would also use it while fixing my dinner over the
camp stove after dark. I loved how it had two different power
levels. It would allow me to have the amount of light I needed. It
would allow me to focus the light to see things far away, but also
allow me to use the lesser light mode to conserve the batteries. I
used one set of batteries for one season.
I have since started using the headlamps while canoeing. The bright
light is very useful on finding the extraction point after dark. I
don't think the lighter, smaller, led lights would have been as
I started using it while bicycling. When bicycling I have be seen
light and seeing where I am going light. This was my seeing where I
was going light. I was able to ride along the path well after sunset
at 10-18 miles per hour safely. I would suggest more light if I was
commuting ever day or riding through the woods, but for what I do, it
is sufficient for the weight.
Items I was concerned about when buying my headlamps.
Battery life, I have not paid a lot of attention to battery life. It
has not been an issue.
Blown bulbs, so far no issue.
Lock switch to keep from turning the light on by accident. It works
when I do my job.
Weight, this is a heavy item.
Corrosion on the battery connectors, my original headlamp has had
issues with the battery connectors since it was submerged in salt
water for an extended period of time.
Final thought, if you know you will be moving at night, this is the
light for you. If you don't expect to do a lot at night, I think
there are many options that don't weigh as much.
