The report found that "Philips lamps did have all the markings on the lamps in contrast to lamps from other manufacturers which did not have any markings at all".
KEMA also addressed performance levels, specifically the light output of lamps for both projectors and rear-projection TV. "Philips lamps have a significantly higher luminance output than the lamps from other manufacturers," concluded the report.
Dave Bethell (pictured) from Just Lamps, an exclusive worldwide distributor of Diamond Lamps, told II: "We are extremely pleased that Philips invested in this important study to confirm what we all suspected - that buying copy lamps is a false economy. Copy lamps are considered because they are cheap but ultimately the user is receiving a product that underperforms in brightness, is of dubious quality and has a compromised lifetime. All these factors leave the buyer disappointed, and expose the reseller to the aggravation of returns and credits and [tarnishing of] their reputation. This is why Just Lamps only distributes the original manufacturers' lamp or Diamond Lamps as a quality alternative. Diamond Lamps uses the same bulb as supplied originally with the projector and therefore gives identical performance, while being more economic. Good for the users' wallet and the resellers' reputation."
