Casio is the original pioneer of lamp - free projector technology and remains the only manufacturer
whose range is completely mercury free, not only ensuring that the teaching environment is safe, but also replacing one of the most unreliable light
sources on the planet (UHP mercury lamps), with two of the most
stable (Laser and LED).
I believe this to be a more
stable and reliable
source of income than, say, the stock market which can plunge just on a misspoken word by a CEO or even a celebrity
whose favorite social network changed a little.
