Overhead Projectors

Dim images

If you replace the lamp in your overhead projector and now it is very dim, you have probably installed the wrong type of lamp. Don't feel dumb, this is very easy to do. If your projector is supposed to use an ENX or FXL lamp, you may have accidentally installed an ELH lamp, which looks identical. The difference is that an ELH lamp is a 120 volt lamp and the proper lamps are 82 volts. The lamp will not be damaged, it just isn't getting the right voltage. The solution, of course, is to get the correct lamp.
