Will Casio render projector bulbs obsolete? Chris Drage is impressed by progress
Early LED-based projectors were disappointing. Most were small and portable but, with low luminosity (around 10 lumens), they were only useful in darkened rooms. Even the best struggled to achieve 50 to 160 lumens, suffered from poor image quality and were not easily portable due to external power supplies. Enter a new generation of Casio projectors.
The new Casio XJ-A135 is light and portable, can run presentations and movies from a USB stick and delivers sufficient brightness (2,000 lumens) for classrooms. And it dispenses with the need for bulbs, the single biggest maintenance cost of projectors. And its LED projector chip has a claimed working life of some 20,000 hours – that's equivalent to 15 years!
