Casio has announced an “environmentally friendly” line of projectors.  The price seems a little bit high for only 2500 Lumens, but I guess that can be justified with the “green” sales-pitch and the cost of replacement lamps.  The average lamp costs well over $300, and has half of the advertised lifespan of this projector, so when you put the cost of a chassis and one lamp replacement together, you’re looking at about the same price.  But how hard set is the 6000 hour lifespan?  If you’re buying a new unit for every two lamps you’re replacing in another system, is this really a viable ”green solution”?  I guess when you factor in the portability of the unit and the similar ROI, you really can’t go wrong with these units, as long as they perform as advertised.
