Introduction to OSRAM Projector Lamps\/ Bulbs<\/strong><\/em><\/h2>\n

As one of the best-selling projector lamps\/ bulbs, OSRAM P-VIP\u00ae Projector lamps\/ bulbs are impacted by many counterfeit lamps. Some of them are very easy to identify, but others are not. No one can guarantee the light performance of those counterfeit P-VIP\u00ae lamps\/ bulbs.<\/strong><\/p>\n

For decades, OSRAM has been committed to providing premium lighting products to the global market. Our mission is to optimize production processes, strengthen quality control and increase customer satisfaction to brighten your screen<\/p>\n

Counterfeit of P-VIP\u00ae Projector lamps\/bulbs have\u00a0up to 30% less initial brightness.<\/strong><\/em><\/h3>\n

OSRAM picked several counterfeit lamps from the market for testing. The result was very surprising. The gap between the initial luminance of counterfeits and OSRAM original P-VIP\u00ae projector lamps\/ bulbs can reach 30% in the worst situation. Too low brightness can make visible defects on the screen. For instance, you may find a blurred subtitle when watching a movie or have difficulty in seeing the projected slides clearly when presenting at a meeting.<\/p>\n

Electrode gap- the main cause for insufficient brightness in projection<\/strong><\/em><\/h3>\n

In lamp technology, electrode gap and brightness are strongly related. A smaller electrode gap yields higher brightness. It is also optimal to have consistent electrode gaps between the same type of lamps. OSRAM performed a sophisticated test on electrode gap to prove that counterfeit brightness levels were less than OSRAM P-VIP\u00ae Projector lamp\/ bulb levels. The test result shows that the electrode gap of counterfeit projector lamps\/ bulbs is larger than OSRAM lamps by 30% on average, which undoubtedly indicates a much lower brightness. As shown in the graph, the deviation of electrode gap among OSRAM projector lamps\/ bulbs is well-controlled and less than counterfeit lamps.<\/p>\n

Counterfeit lamps typically have inconsistent light optics across the screen<\/strong><\/em><\/h3>\n

When presenting with projection, not only vivid colour but uniform brightness distribution all over the screen is the key to the visual feeling. Besides the projector lamp\/ bulb itself, OSRAM takes great care in many application details such as how the lamp perfectly integrates into each projector system to ensure uniform and stable optical output on the screen. This optimization of optics is what the counterfeits of P-VIP\u00aeprojector lamps\/ bulbs cannot replicate.<\/p>\n

Poor maintenance and reliability of a counterfeit of P-VIP\u00ae projector lamps\/ bulbs<\/strong><\/em><\/h3>\n

The endurance of a light source impacts a lot on your practical usage, in a way of functionality and performance. We had a lifetime test with fake lamps and obtained a negative result.<\/p>\n
