When it comes to projectors, one of the most important specifications to consider is brightness. Projector brightness is typically measured in lumens, but there are actually two different types of lumens: ANSI lumens and lumens. In this blog post, we’ll explain the difference between ANSI lumens and lumens and why it’s important to understand this difference.
What Are Lumens?
Lumens are a measure of the total amount of visible light emitted by a source, such as a projector or light bulb. In the context of projectors, lumens refer to the brightness of the image produced by the projector. The higher the number of lumens, the brighter the image will be.
What Are ANSI Lumens?
ANSI lumens are a specific type of lumen measurement that was standardized by the American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) in the past. While the ANSI/ISO standards for measuring projector brightness were retired in 2003, ANSI lumens is still widely used as a term to describe projector brightness. ANSI lumens are measured using a standard set of procedures and equipment, which ensures that the brightness measurements are consistent and accurate across different projectors. This makes it easier to compare the brightness of different projectors and make informed purchasing decisions.
Why Do ANSI Lumens Matter?
The difference between ANSI lumens and lumens is important because it can affect the accuracy of the brightness measurements. Lumens are often advertised by manufacturers as a way to market their projectors, but the actual brightness may be different depending on how the measurement was taken. Without standardized measurements, it can be difficult to compare the brightness of different projectors and know which one will provide the best image quality.
By using ANSI lumens as the standard measurement for projector brightness, consumers can have greater confidence in the accuracy of the specifications provided by manufacturers. This makes it easier to compare projectors and choose the one that best fits their needs.
In summary, ANSI lumens and lumens are both measures of projector brightness, but ANSI lumens are a standardized measurement that provides more accurate and consistent results. When shopping for a projector, it’s important to pay attention to the ANSI lumens specification to ensure that you’re getting the brightness you need for your specific application. With this knowledge, you can make an informed decision and choose the projector that will provide the best image quality for your needs.
