Was 5mW before mod, dunno what it is now. Need to cut a hold just above the button to access the pot
OK, to access the pot, drill a 5mm hole just about 2mm on front of the switch, towards the laser end. The pot is there, careful when adjusting, mine kept cutting out, I had to mess with it for ages to get it to stay.
