Hello Vincent,
I purchased 3 of these lights and loaned 2 of them to Law Enforcement friends.
I have not heard back from one of them (still under evaluation).
The other one had a great review. The low level of light did not glare and destroy night vision, and the beam angle was just right for lighting up a clip board sized sheet of paper. The only problem was the 5 minute run time. It seems he takes longer than 5 minutes to write a ticket.
The third light was sent back to be replaced because of an anoying prominant ring in the beam. It is difficult to read when there is a prominant ring from the light beam.
The small wires are well protected, but there could be some problems when changing the batteries.
When you take the back off to change the batteries, be careful that you do not loose the switch button and spring. When you re-assemble the unit, be sure to position the circuit board correctly. Not a problem, but pay attention when you put the thing together. The tiny screws in my big hands are a little bit of a problem, but I have not lost any... yet.
The switch seems to work, most of the time. When it doesn't work, a twist of the base seems to make it work. I think the battery contacts may be the problem, instead of the switch.
This light is designed for pocket use, taking notes under low light conditions. For that use it works well. I would like to see 180 degree movement of the arm, a clip that would work on thicker things (thicker than pocket material), an easier way to change the batteries (like a snap apart construction) although 40 hours of battery life will not use up batteries very fast, some attention to splash proofing, and I am not sure about the 5 minute at a time run time.
Tom
