The Casio XJ-V1 is a new model (release date May 2015) for which the manufacturer uses the name EcoLite(tm). The unit reviewed was a pre-production unit and it's possible the production units will differ a little in features and/or performance.
This model uses a long life hybrid laser/LED light source, which is unusual to for a projector in this price range, and that combined with no air filter to clear or replace means this is a very low maintenance projector. Casio markets this model as a classroom projector that is also suitable for business applications. The XJ-V1 has 1024 x 768 (XGA) resolution and combined with its very low maintenance requirements make this a great choice for replacing an older, lamp-based, classroom projector, most of which will use the same 4 x 3 image format as the XJ-V1.
The EcoLite XJ-V1 receives our Special Interest award for being a great choice for a classroom projector, as long as network support and an internal speaker are not needed, and when very low maintenance is a top priority.
