Projector lamps have been developed in close cooperation between the world’s leading lighting technology companies and projector manufacturers, matching lamp design to driver electronics and optics to ensure the optimum projected image, reliability and lamplife. The manufacturing process is complex and tightly quality controlled to ensure user safety when the lamp is in operation.
Due to the characteristics of the product it is our strong advice to anyone buying or reselling lamps to work with original manufacturers’ products. If opting for a refurbished product, make sure that an original lamp has been fitted by a company endorsed by the lamp manufacturer.
Use an original lamp as replacement to ensure safe and optimal working of your projector/rear projection television, brightness, lifetime and colours!!
With a worldwide replacement lamp market being about US$1billion worth, copy makers started to step into this business as well. As a result of this, many internet sites offer a variety of replacement lamps for projectors and rear projection television sets. However, there are many concerns over copy lamps both from the bulb manufacturers themselves as the brands selling the projectors and TV sets.
The IP rights on bulb technology are held by the original bulb manufacturers. If a lamp is proven to have infringed IP’s, than anyone selling it, is commercially at risk of legal proceedings.
Secondly, because copy lamps are not being produced in conjunction with the projector development, no guarantee can be given that the copy lamp will work well within the existing lamp setup.
The third concern is a safety issue which raises a lot of questions when using a copy lamp; use of a non-original bulb might cause electrical short circuits which could lead to explosions and fire.
To examine the quality of those “compatible” or copy lamps, compared to the originally Philips manufactured lamps, we started a benchmark study in cooperation with the KEMA test house. Four different lamp types have been measured and compared: two for rear projection and two for front projection of which one based on DLP™ (Digital Light Processing™ is a technology invented by Texas Instruments) technology and one based on LCD (Liquid Crystal Display) technology.
