That half black box in the middle is your laser driver. You have to look for a trimmer
on it which controls your current.
I see that is a potted version, so hopefully the adjust screw is not covered.
The best way to drop the mW would be to pull the laser head and driver, power it
outside of the projector, and have the output tested.
The hardest part will be to find somebody local with an LPM. You could also mail
it if need be, though id still try to stay within your own country and put tracking
on the package.
EDIT*
I just had a look for a similar laser and found this,
By the looks of it, there is no trimmer on those drivers.. I doubt the projector is analogue, so you may have to look
at A) using another driver that can be adjusted, B) try a few different resistors in line with the input to the laser,
C) an ND filter on the lasers output, or D) a small aperture for the beam to pass, blocking some of the output...
