Choose the projector that suits you from the brightness of the projector.
Keywords: Projector. Brightness. Lumen. ANSI Lumen.
When we buy projectors, we often see the words 300ANSI lm, 2000ANSI lm, 3000ANSI lm and so on.
What does this "ANSI lm" mean? Is the number the higher the better? Let's find out together.
# What does this "ANSI lm" mean?
Firstly, we need to know that the light output refers to the output of the light energy by projector, in "lumen" (lm). According to the difference of test standards, the units commonly used to measure the light output of projectors on the market are ANSI lumen and ISO lumen.
ANSI lumen is established by the American National Standards Institute (ANSI, American National Standards Institute); while ISO lumen is an international standard established by the International Organization for Standardization.
ISO lumen is mainly used by leading manufacturers in the projection industry such as Epson, while brands using DLP projection technology solutions prefer ANSI lumen. Therefore, ANSI lm is a unit developed by the American National Standards Institute to describe the strength of the projector's output light energy capability.
# Is the number of ANSI lm the higher the better?
* To comprehensively consider
Probably not the higher the better. Brightness is indeed important for projection, but not the only criterion for measuring whether a projector is good or not. Besides brightness, when purchasing a projector, it is necessary to comprehensively consider the very important parameters such as the resolution, contrast, and color gamut of the projector. Because the projector can bring us a good sense of experience, it is rooted in an excellent ratio of its overall parameters. It is by no means by making a single indicator excellent.
* Pay attention to the high brightness but low resolution projector
At present it is undeniable that there are some machines with high brightness but low resolution. Their promotional selling point is high brightness, which can often reach four or five thousand ANSI lumen. Coupled with a good price, it is called high cost performance. Many consumers who do not know much about projectors are easily deceived. Because if you carefully observe the projection effect of the projector, you will find that the resolution of this type of projector is often not high, most of which cannot reach 1080P, and some are even lower. Big difference.
* Pay attention to the high brightness and low color gamut projector
There is also another way, with high brightness and low color gamut, which can improve the brightness of the picture simply by processing the filter. However, such kind of projectors often achieve high brightness by sacrificing color. The color of the projected picture is not correct, and even looks white.
Therefore, some merchants in the market often use high brightness and low prices to attract consumers' attention, but we still need to establish a clear understanding when purchasing projectors: if the buyer wants both high brightness and high brightness but lower cost, merchants will inevitably sacrifice resolution, color gamut, and contrast, which are equally critical indicators, for cost considerations.
# To sum up
When you are looking for projectors in batches, you can ask the source manufacturer for help. That is a more sensible choice. On the one hand, you can get products with a more suitable unit price. On the other hand, because the products from the source manufacturers are all factory-made, by contacting the factory, you can learn about the actual and real-time production process, product quality inspection and control, company and factory scale, and service ability, to more fully assess the quality of products and service capabilities of your future partner.
