I just had a look at the documentation and its been classified as a Class 2M laser by the manufacturer, In the UK its legal to own any laser even nasty Class 4s, but if you are using it outside and get deemed to have misused it(even if you haven’t) then it comes under some pretty nasty laws with serious penalties
I totally understand that this doesn’t output coherent laser light , it is simply exciting phosphor with one but with that classification it could be tricky to defend.
The trouble is they(the police) are going to see this pencil thin beam quite unlike any normal flashlight they have ever seen , check the manufacturer see Class 2m Laser and arrest you probably then offering you a choice of surrendering it (confiscation) or taking your chances in court , either option kinda sucks.
It really doesn’t help the situation having sellers referring to it as
