And why are they important? Officially called ANSI lumens, this measurement shows how strong a light source is. In projectors, this relates directly to the environment where the projector will be used.
So what are lumens? Lumens are the measurement of brightness that a projector gives out. The Projector Expert reports the following lumen counts of common light sources:.
There are three key light sources in the projector realm, those being LED, laser, and lamp. This is because LED projectors have improved color saturation and luminous efficiency, which allows LED projectors to appear to have a higher perceived brightness than their ANSI lumen measurement than they may actually possess.
Learn more about LED lumens. There are a variety of factors that affect the level of brightness needed for delivering a quality picture. However, a key takeaway is the two factors that impact projector brightness requirements are:.
By definition, ambient light is light that is already present in a scene before any additional lighting is added. The most common example of this is natural light coming in through the windows, or normal room lights.
Spaces with lots of lighting need a higher brightness to deliver quality images. In a darker space, you can use a lower brightness, combined with a higher contrast ratio. The ideal lumen range for multi-purpose spaces is to lumens. Sure, portable projectors aren't designed for grand cinematic experiences, so they don't need thousands of lumens, but we'd put the entry point at Based on the information above, you may wonder if a model with higher brightness can be applied to various projection sizes and ambient lighting requirements while guaranteeing clear images with excellent color.
Not necessarily. For home theater systems, we recommend that consumers choose a projector with appropriate brightness to show the clearest images with the best color performance and contrast ratio effect.
The light processing components of a projector consist of the projection lamp, which determines the highest brightness output, and color wheel, which controls color performance. Light transmission, and therefore brightness, will be compromised when it is necessary to meet pure color requirements. So instead of pursuing high lumens, projection brightness must be controlled within an appropriate range to increase color accuracy.
When selecting a projector, there are many specifications to consider. Among them, one of the most critical specifications is brightness. Only with appropriate lumens for the throw distance and ambient lighting in your situation can the projector produce spectacularly clear images with true colors. This is particularly crucial for consumers choosing home theater systems.
These criteria are very helpful when choosing projectors, so you can ensure the most enjoyable viewing experience for your family with the ideal home theater system.

Variations differ from projector to projector, so contact a Projector People representative to find out more. Quick Tip: Home Theater projectors are typically measured in video mode for a more accurate specification for brightness. Projectors for home theater also offer better video scaling and contrast ratios than business projectors.
