There are 24 diodes in the projector (2 @ blocks of 12 diodes each)
This is one of the reasons we hesitated to make it public
The BenQ projector is more expensive than the Casio M and H series
The Casio projectors have more diodes (and a powerful red and a blue LED) AND these 9mm appear to have about the same output as the 5.6mm
The biggest difference we can see for now is that the 9mm diodes include an ESD protection circuit inside the diode
The laser diodes are the only light source in the BenQ projector
The projector gets BOTH red and green light via a phosphor disk
The collimation lenses are glued (via a pot metal "scaffold") directly to each individual diode can
Sometimes the diode window is broken while removing the lens
Peace,
