General:
The three functions of the lamp can be switched by a button in series (first laser pointer, then UV, then white light). The processing from the outside looks stable. The loop could be 1-2 cm longer; because then they would have fit well around the wrist.
Laser Pointer: ***** (5 stars)
Strong laser pointer. Very easy to see even in bright light conditions. So I am very satisfied.
UV light: ***** (5 stars)
Before, we used a small ultraviolet flashlight that threw been spotty light. This here is really very good. The result is a fairly large cone of light (30-40 cm), with the can very well find something even if it is not totally dark. So I'm also very satisfied!
3) white light: *** (3 stars)
The white light is too dark. There is a lack of luminosity. So I took it out again my "old" flashlight. Here really room for improvement! The 10 LED diodes do not throw enough light in not quite dark rooms. Experience here: OK ... but nothing more.
Conclusion:
Who needs a top UV lamp for geocaching, with which you can "scan" large areas in a short time, is well advised here. Also the laser pointer makes very good job. Only the actual flashlight function can not completely in dark rooms left something to be desired luminosity. The wrist strap I can not ummachen (and I have very small hands). As should either ran a long loop or a carabiner. Weights I the three main criteria the same, I come to 4.2 star and still give off a buy recommendation. I'll keep the light.
