Explanation of terms
Lamp modules are made up of two main elements: the lamp (or bulb) and the cage (or housing) including electrical connector.
Lamps – are effectively ultra high-performance lights developed by the world leaders in lighting technology working in close cooperation with the projector & rear projection television manufacturers.
Cages – are housings produced by the projector manufacturers to accurately seat the lamp and enable user replacement (each physically different projector model usually requires its own bespoke cage design).
Original Lamps are those manufactured by the original lamp developer holding the technology patent (e.g. UHP™ from Philips).
Compatible Lamps are lamps that are not the same type as the original lamp placed in the projector by the projector manufacturer. Specifications about brightness and lamp life are always based on the lamp system, which is the lamp and electronics that are designed to warrant safe operation and good performance of the system. Non-original lamps could be copy lamps.
Copy lamps are lamps produced by unregulated manufacturing companies not holding the technology patents & not pre-installed by any projector manufacturer.
Copy lamp modules are copy lamps fitted in replica cages produced by companies not endorsed by the projector manufacturers.
Refurbishing (or re-lamping) is the process of removing a used lamp from its cage
