Benefits:
+ Really handy small
+ The light output is really incredible high
+ The focusing capability is pleasant (for my purposes)
+ 2 light levels (and a flashing mode)
+ Processing is okay
Neutral:
o lamp always starts at full brightness
o Square spot with strong bundling (see picture)
o as a high beam, the beam is not focused enough (I do not care)
Negatives:
- Focus is too loose (moved in the pocket again)
- To waterproof I do not think (splashproof already)
All in all I would say: definitely a good little light "always with lamp" and for my purpose (illuminating the ground when walking or even in other dark corners) it is ideal. By the darker stage they can also be on the desk once used for crafting (without being blind).
Conclusion: RECOMMENDED! As a handy surface emitter is ideal.
ADDENDUM: with (3.6 volts) 14500-he brings the battery lamp its 300 lumens, I think! In comparison, I would say: the poor performance stage with 14500er is even brighter than the strong level with a new AA battery!
