Brilliant high-level presentations. The 3M Model 9550 Overhead Projector has 4,000 lumens of brightness that shines from edge to edge. With the varifocal triplet lens you can project from a variety of distances. Lamp brightness is adjustable, and the two-lamp system has easy up-front access. The 9550 features a 11.25" x 11.25" stage.

The 3M 9550 overhead projector is easily portable and ready to go once you remove it from the box--there is nothing to be assembled. The post assembly that holds the projection head aloft is hinged against the body of the unit, and a loosening turn of a knob swings it into place.

The body is well designed and made of a sufficiently durable grade and weight of plastic to make this model a good choice for heavy usage. Simple to use, one switch turns the projector on and off, and a separate control panel allows you to change the lamp to high or low intensity. The lamp bulb is easily changed, and the power cord can be neatly wrapped around twin brackets at the bottom front.
