OEM lamp modules use the original manufacturer bulbs and original cages that exactly match what was in the projector when it was new. This is why some of our projector lamps are used in numerous different models from more than one brand. One of the quirks (i.e., confusions) of the modern projector market is that numerous manufacturers can license the same model of a projector, differentiating by resolution rates or lenses, but utilize the same exact module. This isn't to say that every module or bulb only fits in one projector. While many lamp modules look the same, the bulb inside may have different optical characteristics to meet the specific needs of different projectors. ![]() Additional variables are ignition and running voltage of the bulb, reflector size and shape (elliptical or parabolic), lumen ratings, and focal distances. The wattage (lumen output) of the bulbs used in different projectors varies greatly depending the type of projector application: classroom, portable, conference room, large venue, etc. One question we frequently get about replacement lamps is the compatibility of the module and the projector. In order to encourage end users to replace the entire cage and bulb, they occasionally mark down the prices on complete modules in order to discourage damaged projectors and returned bare bulbs.

In many cases, an internal timer on the projector or TV will indicate when it is time to switch the lamp. These projector lamps are the essential part of the unit, producing the light that is required to project the images. When a projector goes out, it is often not the electronics or wiring or case that fails, but the bulb that powers the projected image. Consumers have also been huge purchasers of projectors and rear-projection televisions (RPTVs), although these are declining in popularity as flat screen LCD and LED TVs have come onto the market. Projection technology has become ubiquitous, with churches, theaters, and classrooms using multimedia and front end projectors to display presentations. ![]()
