While the measurements are actually more complex than that, you can see that the ANSI lumens measurement method involves several components that help provide a more accurate total. These measurements are then averaged and multiplied to account for the total projected area.
This includes measuring the white contrasts fields at specific spots located on the screen or medium you project onto.
(Projectors did not begin using the ANSI lumen measurements until much more recently.)ĪNSI lumens are measured through more scrupulous methods that involve several variables. This is because, in 1992, the American National Standards Institute (ANSI) standardized the way lumens are measured. A lumen observation is generic and somewhat subjective.ĪNSI lumens, however, tend to be more accurate. Measure what is known as the “luminous flux”. Some projectors list ANSI lumens instead of just lumens. The brightness levels produced by your projector actually affect the quality of the images displayed by your device similar to how the digital zoom can affect the image quality as well which we explained in more detail in our guide.Ĭheck out our recommended projectors to ease your worries about lumens and other projector specs. When you see a projector lumen listed, this refers to the level of brightness your device can produce. (I will briefly go over the some of the other specs that affect image quality below, but you can find my in-depth explanations on my Ultimate Projector Buyer’s Guide.) However, one of the most commonly misunderstood specifications is actually one of the most important. Contrast, throw ratio, light technology, and input capabilities are often listed in the specifications for all projectors. There are a lot of features and specifications you will want to evaluate prior to investing in a home theater projector. Which is bestįor you? Keep reading to find out. Resolution and ambient light – the lumens you need may fluctuate. However, if you are in a room filled with ambient light, you should look for a projector with at least 4000 lumens.įor a truly custom approach, understanding lumens and whatįactors affect the amount you need is vital. ANSI lumens provide a more realistic brightness measurement, although is not always provided.įor most home theater projectors, lumens should measure between 20 lumens when moderate ambient light is present. So what are projector lumens and what do they mean for your home theater set up? Lumens measure the brightness of the picture produced by your projector. However, I found myself constantly questioning what these As with all my electronics, I knew to compare When I was looking for the perfect projector for my home
