That’s because large monitors are still relatively small as they are only “affordable” up to about 71”-80”. Whether in a classroom or auditorium, no longer does the room have to be made dark!įrom a practical standpoint that gives projectors a significant advantage over very large monitors in most environments. This screen type, combined with far brighter projectors, has taken projectors out of darkened rooms and into the light. They allow users to be able to project in rooms with a respectable amount of ambient light, filling a large screen with far less loss of contrast and color saturation than with traditional screens.

Once a lens is detected, the projector may adjust its maximum brightness level.Īmbient Light Rejecting screens started becoming popular less than a decade ago, and for good reason. For some interchangeable lens projectors, max brightness might vary depending on the lens utilized.

This is because it is more common for a projector to be zoomed in a bit than installed at full wide angle. That should give a pretty good approximation of ANSI lumens unless a projector’s brightness rolls off excessively at the edges, meaning the image is brighter in the center of the screenįor the rest of the modes, we measure them at mid-zoom, so the iris is closed halfway. We take 3-4 readings at about 15-20% out from the center of the lens. It might be helpful when comparing two “LUX” rated models in a manufacturer’s own lineup, but this spec can’t be used to compare brightness with another manufacturer’s projector.įor each projector we review, we measure brightest mode at full wide angle – this is with the iris wide open, so the most amount of light gets through. Since these are not a universal standard of measurement, these proprietary ratings can’t be used to compare brightness between projectors from different manufacturers.

Sometimes manufacturer may rate brightness in other ways like Lux, ISO Lumens, Peak Lumens etc. When rated brightness is listed in anything but ANSI lumens, it is pretty much a meaningless number especially when trying to compare projectors from different manufacturers. The industry standard for measuring brightness is ANSI lumens. Your K-12 school might have the funding from technology grants to purchase the hardware initially, but money for routine maintenance, including replacement lamps might be scarce. The result of not having to change out bulbs could save money and time in the long run. While the savings isn’t as dramatic there is also a benefit to running a laser projector in ECO because it can extend the life of its laser light engine by several years as well. One big advantage of spending more at the beginning for a brighter projector is that you can run it in eco-mode, ultimately saving money by increasing lamp life. In this report, we refer to very bright, more capable projectors typically as either Higher Education or High-End projectors.Įven though you may not need a very bright projector, let’s look at the reasons to step up to a brighter projector. A quality 4,000 lumen projector with a high-color lumen output should be bright enough for typical large lecture halls, but brighter 5,000 to 8,000 lumens might serve this application better. The larger spaces like a 100+ seat university lecture hall will require a bigger, brighter, and more expensive projector. If there isn’t direct sunlight striking the screen, most modern education projectors should be bright enough to do the job in a typical K-12 classroom. At the worst, the presenter might have to turn off half the bank of lights to improve visibility. Most projectors on the market are bright enough for an 80″ diagonal screen, the size commonly found in a typical classroom, conference room, or training room even with all the fluorescent room lighting on. That’s three times the brightness produced by the average education projectors from just a few years back. Even inexpensive projectors for K-12 schools can deliver 3,000 – 4,000+ lumens. Today’s projectors are brighter than ever and that means that ambient light isn’t the problem it was a decade ago.
