ANSI Lumens Standard for Projectors
The American National Standards Institute (ANSI) lumens standard is a key method for measuring projector brightness. ANSI, a nonprofit organization, develops standards across various industries, ensuring manufacturers provide accurate lumen values and maintaining consumer trust.
What are Lumens?
Lumens measure the light output of a projector. Before ANSI standards, many manufacturers reported only peak lumens—maximum brightness at startup—which often decreases shortly after. ANSI assesses brightness by considering factors like light output, beam intensity, and operational duration.
Standard Development Process
ANSI standards are created with transparency and balance. Members can propose changes, which require public review before approval. Standards are updated or reaffirmed every five years to remain valid.
Consumer Tip
Always check if a projector meets ANSI lumens standards to ensure accurate brightness measurements.
