Understanding Projector Lumens: A Buyer's Guide

Shedding Light on Brightness

When shopping for projectors, you'll see terms like "Lumens," "ANSI Lumens," and "Lux." It can be confusing. Let's break it down so you know exactly what you're getting.

What are ANSI Lumens?

ANSI Lumens is the standard measurement of brightness as defined by the American National Standards Institute. It measures the average brightness of white light across nine points on the screen. This is the most honest metric to compare projectors.

How Many Do You Need?

  • Dark Room (Cinema): 200+ ANSI Lumens is sufficient for a clear 100-inch image.
  • Dim Room (Some Light): 500-1000 ANSI Lumens helps cut through ambient light.
  • Daylight: 2000+ ANSI Lumens is required for visibility in bright environments.

The LIMOFF HY300 Pro is optimized for dark and dim environments, delivering stunning contrast where it matters most—your movie nights.
