Guide to Projector Lamps
The Projector Lamp, otherwise known as the a projector bulb, is a replaceable part of the projector that needs to be maintained according to the lamp life of the projector, which averages between 1,000 and 2,000 hours. It is easy to calculate the cost of projector lamp replacements by determining how long it will take to reach X amount of hours of lamp life. Depending on whether you’re using a hi-watt bulb or low-watt bulb, projector lamps range upwards of $300. You get more life based on how much power your lamp is using. Projector lamps become quite an expense over time.
Projector Lamp Technology
Lamp technologies such as Metal Halide Lamps, were invented from studying the electrical discharge of a lightning bolt, and continue advance for the specific requirements of the projector. High Intensity refers to the magnification of electrical discharge.
Ultra High Performance, or UHP
High color rendering and a life time of over 10,000 hours. This UHP technology sends electrical discharge between electrodes in an environment of a high pressure Mercury vapor cloud.
Xenon Arc Technology
Very common for movie projectors and a similar technology to UHP, Xenon Arc Technology can be seen in IMAX Theaters with its extremely high spectral distribution and high luminosity. Instead of using Mercury in UHP technology, Xenon gas is the medium between electrodes and under a pressure of around 300 atmospheres.
A common technology for home theater projectors and business projectors, without the problems of flicker or intermittence, this Ultra Violet lamp illuminates a consistent brightness with a projector lamp life up to 6,000 hours.
A type of metal halide lamp that is very high luminance and long lasting performance, this is used for video projectors.
