Two things struck me odd about this projector.

First, I did not know Martin made such a large projector.
Second, the use of a 442nm module.
Wavelengths
Blue .................................................. .................................................. ............................... 442 nm +/-3 nm
Green............................................. .................................................. ............................ 532.5 nm +/-0.5 nm
Red............................................... .................................................. ................................... 655 nm +/-5 nm
Has anyone else looked into the use of 442nm?
