PRO:
+ The lamp is very bright
+ The light duration is higher than 2H (more I have not tried)
+ It used standard 18650 batteries, which are readily available
+ Really waterproof (up to 19m tested)
CON:
- The piezo switch is an impertinence: afloat hardly operable underwater with a lot of feeling
- Because you have to remove the batteries to charge, it is clear that the O-rings are broken soon, they also tend to make when screwing independently, thus actually allowed the Battery Replace only indoor.
- Replacement O-rings are in though, but a pair will not take long and rich replacement I could find so far nowhere.
- The light has a slight blue tint, and the reds are neglected.
- Now the Lowlight: the second charging the batteries using the supplied charger, there were a few minutes later a loud bang and smoke - the charger had goodbye; I was thankfully absent and could prevent a fire.
RESUMEE:
Very convenient and bright lamp, one must of course at the cost of some drawbacks. But the charger is dangerous, I can only recommend to throw the cheap China part immediately in the garbage and to get a real.
