Convert between projector Lumens and screen Lux. Calculate light intensity on the screen surface to ensure a vibrant and clear image. Accurately modeling light distribution is essential for predicting the real-world performance of your projector and screen combination.
Calculating Lumen & Lux is a fundamental and crucial step in home theater design. It is not just about measuring distance; it must be designed based on scientific evidence to maximize human visual perception limits and immersion. Incorrect settings can cause eye strain or fail to take advantage of resolution benefits. This tool complies with industry standards such as THX and SMPTE guides to provide the most precise data.
This system utilizes complex trigonometry and optical formulas. Based on the input variables (screen size, resolution, viewing angle, etc.), it simultaneously calculates the minimum distance where pixels do not appear clustered and the maximum immersion distance that fills the entire field of view. All results are reflected in real-time, suggesting figures optimized for the user's environment.
For a dedicated dark room, 1,500 to 2,000 lumens is plenty. For a room with some lights on, you should look for a projector with 3,000+ lumens and an ALR screen.
Lumens measure the total light output from the source (projector). Lux measures the light intensity landing on a specific surface area (the screen).
Yes. ANSI Lumens are a standardized measurement across the entire screen area, making it a much more reliable metric for comparing different projector brands.
