I'm talking about these MEMS based small video projectors made by Sony and Celluon. They are not galvo based or just using a laser and phosphor as a light source but scan lines of a video vertically with tiny mirrors I believe.

Firstly I'm surprised about the brightness, 37 lumens?? Is the lumens with these scanning projectors relying on persistence of vision different from lumens from regular video projectors or is it just the 80,000:1 contrast ratio?

Secondly I'm surprised why it has a 2000 hour laser life. What kind of diodes are they using that have such short lifespan?

if anyone had these projectors and can share their experiences maybe? In the youtube videos it appears a bit too bright for 37 lumens provided its the same ANSI lumen I'm familiar with even in the pitch black ambient conditions.

Another video of the Celluon Picopro, start watching from 6:40 https://www.youtube.com/watch?v=MeHNzgP4d8I
