How ANSI Lumens Affects Your Viewing Experience

How does brightness affect your viewing experience on a 4K projector

When buying a projector, it’s important to consider what you will be using it for and where you will be using it, so you can determine which projector best suits your needs. Factors that are usually considered include price, the clarity of sound projection and color display, and the lumens a projector is capable of achieving. A lumen is a unit of measurement which describes the brightness of light emitted by an object, and without significant light emission, a projector cannot display brilliant pictures. In order to optimize your viewing experience, Formovie measures the lighting capabilities of projectors in ANSI lumens and offers a range of projectors to suit different needs. 

The Difference between Lumen and ANSI Lumens

Although both are units that measure light, there are distinctions between them that make each unique. Lumen is standardized by the International System of Units, and it estimates how much light is emitted from a light source over a period of time, from a fixed angle. As such, this is the best unit of measurement to use when deciding on a lightbulb for the interior of a home, or a spotlight for the exterior.   

ANSI lumen is the luminous flux unit standardized by the American National Standards Institute (ANSI). It is used to describe the light that is emitted specifically by a projector. Testing the ANSI lumens of a projector involves placing it at a certain distance from a white screen, and calculating its  brightness at nine fixed points on the screen with a light meter. The most accurate reading is achieved when the projector is the only light source in the room.

Do More Lumens Guarantee Better Projection?

Higher lumens do guarantee brighter illumination, but not necessarily better projection. In order to fulfill the function of displaying high-quality images, the design of a projector must consider how the light component and the color wheel work together to reproduce colors accurately. So even a high lumen lamp can lose significant brightness when the necessary adjustments are made to accommodate the display of Red, Green, and Blue (RGB) colors. 

How Much ANSI Lumen Is Suitable?

Because the ANSI lumens capacity of a projector is best tested in a completely dark room and from a specific distance, changes in lighting conditions and room size can affect the display. Here is a breakdown of the approximate range of ANSI lumens needed in different conditions:



  • Ambient Light:
        • Dark room: 300~600 ANSI Lumens
        • Medium Dark: 600~2000 ANSI Lumens
        • Room with Daylight: More than 2000 ANSI Lumens
        • Sunny Day Outdoor: 2500~3000 ANSI Lumens
  • Room Size:
      • 15-30㎡: 100~800 ANSI Lumens
      • 35-50㎡:1500-2000 ANSI Lumens
      • 60-100㎡:3000-4000 ANSI Lumens
      • 120-200㎡: More than 4000 ANSI Lumens

    With this guide, you get a better understanding of how much power your projector must have to suit your needs. For instance, a standard classroom using the projector during the day would need a projector with at least 3000 ANSI lumen to get the best picture quality. Whereas someone living in a chick little apartment and only watches TV in the evening can get an excellent viewing experience with around 600 ANSI lumen.
