    Im a teacher looking for a suitable and cheap projector for the classroom. At the moment i am considering the following:

    1. the BenQ CP220 c for 480euro or

    2. the infocus x21 for 414 euro.

    I was given rough guidelines- look for short throw, min 1600 lumes, XGA resoultion etc....

    Can anybody help me out with this????
    Thanks a million,

    a confused teacher.;)

    Hi Ken,

    Projectors suitable for schools have seen a major change over the ast 12 months. With the integration of Smart Boards (Interactive Whiteboards) into the classroom becoming the norm, the best suited projector have changed.

    As the Smart boards involved the user continually entering the projector beam, Short Throw Projectors have become the choice for most classroom setup. The short throw lens means the projector is very close to the board/screen (usually within 1mtr) eliminating alot of shadowing caused be the users body.

    Another important point is the projector brightness. BECTA have a recommendation in the UK for classroom projectors to have a brightness rating of 1500 lumens. This is to prevent eye damage caused by looking directly into the lamp and eye strain from continuous exposure to a bright screen. One major down side to this recommendation is that 1500 lumens is only sufficient for projecting in a reasonably dark room. Increasing this to 2500 will allow the projector to be used in a room with some ambient light.

    A simple solution to this and what we mornally recommend is to purchase a projector with a brightness rating of 1500lumens in ECO Mode, which will normally give you a brightness of 2000 - 2500 lumens in STD mode. This means the projector meets the BECTA recommendations and also give you the option to increase brightness on one of those few bright sunny days.

    Following this, I would suggest "if the budget allows" to purchasing a Short Throw projector with a brightness rating of 1500 lumens "in ECO mode" which has a minimum of XGA resolution.

    HTH.
