To make sure this projector is the right fit for you room

Featuring laser phosphor illumination, the Christie DWU550-GS 1-chip DLP projector eliminates the need for lamp and filter replacements, providing 20,000 hours of low-cost operation. With its small footprint, low-weight, quiet operation, the Christie DWU550-GS is ideal for boardrooms, higher education, museums and smaller location-based entertainment venues.Pure laser, also known as 3-Primary (3P) or RGB laser, generates light directly from three individual red, green and blue lasers. The primary benefit of a RGB laser system is light output while also achieving higher performance in other standard image quality parameters such as colour gamut, contrast ratio and dynamic range when compared to standard lamp-based systems. As such, RGB laser is ideal for large-format applications.Laser phosphor illumination, such as what?s used in the Christie GS Series, uses a blue laser diode as the light source instead of a high intensity discharge (HID) lamp. To generate the three primary colours, the laser diode shines laser light onto a phosphor wheel to create yellow light, while blue laser light passes though an opening in the phosphor wheel. The projector then sends the yellow light through a colour wheel to generate red and green, while the the blue laser light passes through a diffusion window. These red, green and blue colours are then directed onto an imaging surface, such as a DLP chip, which sends the light through a lens and onto the projection screen. The advantage of a laser phosphor projector is the long life of the illumination system before it reaches 50% brightness. As a lampless system, laser phosphor also eliminates the need for lamp and filter replacements, reducing the down-time, maintenance and costs associated with lamp-based projectors. The long-life and low maintenance of laser phosphor projectors make them ideal for corporate boardrooms, classrooms and location-based entertainment.
