Independent research paper on UHP™ lamp performance.

UHP™ lamps have significantly higher luminance.


Over the past years, an increasing number of third party suppliers and manufacturers have entered the market for replacement lamps used in RP-TVs and projectors. As the global leader in lighting solutions for projection applications, Philips has developed an extensive track record in OEM projects with all major TV and projector brands.


With production facilities in both Europe as well as Asia, Philips is able to offer consistent high quality thanks to the many years of experience in this specific field of the lighting industry. To convince consumers that it's better (both for performance as well as safety) to use original lamps instead of compatible (copy) lamps, KEMA was asked to do an independent technical benchmark study. The key findings are explained below.


During the examination lamps which are available in the aftermarket for Rear Projection TVs of different manufacturers were compared with the original Philips lamps.


TV projection lamps were tested on two Rear Projection Television sets, one made by Samsung and based on DLP™ technology and one made by Sony and based on LCD technology. On the DLP™ TV set, Philips lamps offered on average 54% higher luminance compared to the alternative lamps. For the LDC TV set, the Philips lamps offered on average 218% higher luminance than the lamps from other manufacturers.


The overall conclusion may be that the original Philips lamps for Rear Projection DLP/LCD TV give a significantly higher luminance in the given positions than the lamps from other manufacturers. For the consumer this will mean that the perceived overall performance and brightness of the screen will be better.



These conclusions are valid for the following TV lamps:

- P22 1.0 100-120W Measured with a RPTV on the basis of LCD technology

- E23 1.0 100W Measured with a RPTV on the basis of DLP™ technology
