The lamp is meticulously crafted, the matt black case is relatively insensitive to fat fingers. The on / off switch sits hidden behind the screw, which makes one-hand operation difficult.
Also the focus requires both hands because it is quite difficult to move. This will certainly change in the course of use. Hopefully he will not "baggy" to. Focuses strongly reduces the hitherto uniformly illuminated circle to an image of the LED, and the uniformity of illumination is lost.
The light intensity is indicated as 140 lumens, but looks much brighter. In any case, one should - Never look directly into the beam of light - as with any flashlight. Something like this can easily lead to permanent damage to the eye.
Conclusion:
I have nothing to complain about at this lamp, so 5 stars! If you "not helpful" find this review, please post a comment. This helps everyone involved more than meaningless "unchecking"!
