No meter Jim but it 'looks' 50mW compared to the LaserWorld 250mW. Just took picture of it with an IR filter on camera and no noticeable attenuation so if that is a test then yes it seems fine.
Also I smoked the room now it's getting dark and the beam is very tight indeed. It was just the splatter of the 'blob' that I was looking at.
Realistically I don't expect it to last long but for £12.50 I'm happy.
I'll order another one to take to bits to see what can be done with it.
BTW - Has anyone got details for a DIY meter?
A lovely childhood. Just me my mother and the voices.
