Projector Brightness and Contrast: Two Important Specifications to Consider Before Buying

Posted by on for ProLampSales

Digital projector specifications always include values for brightness and contrast. While there are many factors that determine the best projector for an application, knowing the brightness and contrast may quickly qualify the projector, or not, for it’s intended use. Brightness is projector light output measured in lumens - the higher the lumens, the brighter the projector. Generally, projector prices go up as lumen output increases. Contrast is presented as a ratio between the brightest and darkest areas of a projected image. Brightness Projector light output ranges from less than 100 lumens to more than 10,000 lumens. Projectors can be roughly...

Where Do Mobile Projectors Fit in the Projector Matrix?

Posted by on for ProLampSales

When most people think of digital projectors, the images that come to mind are of substantial pieces of equipment with multiple input sources, brightness from 1000 to 4000 lumens and large projected image size that weigh-in at 5 to 10 pounds. Usually these projectors are permanently mounted on walls, ceilings or tables in home theaters, conference rooms, classrooms and church sanctuaries. There are three categories of projectors built for mobility and designed for small group or even one to one presentations. These projector categories are Portable, Pocket and Pico. Portable projectors function as both video and data projectors and they...

The images seen today on computer monitors, tablets, smart phones and HD televisions provide full range, saturated, vibrant color. This viewing experience leads to the expectation that, when projected on a large screen, these images will retain the same depth and richness of color. That expectation has not always been met. Digital projectors use...
