EHJ Projector Light Bulbs

EHJ projector light bulbs are used in many types of overhead projectors including Apollo and 3m among others. The 250 watt, 24 volt rating provides high illumination in certain types of small viewing equipment. They are designated by a three letter code EHJ which you should see on the back of the lamp itself or inside the projector. Sometimes people are confused by code numbers from manufacturers but the only thing you really need to identify any projector lamp is the three letter code which in this case is an EHJ projector lamp.
