3M 1780 Overhead Projector
The 3M Overhead Projector Model 1780 is a cost-efficient, durable and easy-to-use overhead. The rugged glass stage is designed to result in less repairs since it is break resistant and able to withstand the rigors of classroom use.
The 2500 lumens of light yield clear, crisp images which are viewable in just about any location of the room. The included lamp changer means that you won't have to stop and replace a burned out lamp should one blow during a presentation. Your audience will never be left in the dark.
The system is easy to use - focusing is a breeze and the machine itself is easy to clean. To that end, the head is closed which means less dust, less maintenance and less classroom interruptions which means a more organized, professional presentation.
- The articulating head produces clear images throughout the entire tilt range
- The bright 2500 lumens means that images will be visible even when the lights are on
- In-circuit resistor to extend lamp life
- There is only one switch for instant bulb replacement
- A lamp interrupt switch shuts off power to lamp when changing to prevent premature failure
- A thermal protection circuit cuts power to the lamp if the projector exceeds safe operating temperature
