The difference between Ansi lumens and lumens

1. ANSI Lumens and Lumens

First of all, we need to know that ANSI Lumens and Lumens both indicate the brightness of the projector. The brightness of the projector is the light emitted by the projector, which will make the image of the projector have a certain brightness. The higher the brightness, the clearer the projected image, and vice versa. Then ANSI Lumens and Lumens are two common units of brightness.

ANSI Lumens refers to the brightness of the projector screen, that is, the brightness of the screen displayed after the projector is projected onto the wall. Simply put, it is the brightness that we can see with our naked eyes. Because the light of the projector will be weakened in the process of projecting onto the wall, we can use the ANSI standard nine-point method to test and get the brightness of the screen we see in the end. Using ANSI lumens to indicate brightness is generally recognized internationally, and it is also more accurate to restore the brightness of the screen that our ordinary users perceive.

Lumens generally refer to the lumens of the light source, that is, the brightness of the light source used by the projector. Since this type of brightness has not been weakened, the value is often very high, but it does not represent the brightness we see. The brightness of the screen of this type of projector will be lower than the brightness represented by the value.

2. Which unit should I refer to when purchasing a projector

Now the projector industry is mixed. Some projector merchants take advantage of users who do not know the knowledge of projectors and start playing word games. They mark some parameters such as 80,000 brightness without specifying the unit. We must pay attention to distinguish when purchasing, and look for recognized brightness units such as Ansi lumens or lumens. Then some customers may have questions, which of the two brightness units, Ansi lumens and lumens, should I refer to?

Fullsun recommends that you refer to the brightness unit of Ansi lumens. After all, the brightness we can actually see is the brightness of the projector screen. The higher the brightness, the clearer the picture will be. For projectors that use the brightness unit of lumens, they can actually be converted into Ansi lumens. 1 Ansi lumen is approximately equal to 4 lumens. After converting, friends can make comparisons and choices, so that they can choose their favorite projectors.
