One of the significant developments for this year is the advent of LASER-LAMP-MODULES into the newer laser projectors. Like Xenon lamps of yesteryear, Laser projectors can now also have the lamps replaced in the field. This removes a large issue exhibitors have had with laser projectors in that if the laser lamp dies, the whole projector needs replacement. This is no longer the case.
