Brightness matters when it comes to picture quality. Our projectors’ lumens are measured to ISO and IDMS standards. That's the difference between dull and dazzling.
Lumens are the standard way to measure how bright a projector is, based on the total light it gives off. This is different from lux, which measures how strong the light is in one area — both are useful but used differently. For projectors, lumens make it easy to compare brightness across different models. Epson follows official standards to measure white and colour brightness, so you can trust the results to match everyday use.
The key to exceptional projection performance
Lumens significantly impact a projector’s usability and viewing experience. Epson’s commitment to True Lumens ensures:
Reliable clarity in
any environment1
Brightness suitable for both
well-lit
and
dimly lit rooms.
Vivid colour
accuracy
Equal white and colour brightness
for lifelike visuals.

How a 1,000 Lumens Epson
Outshines a
12,000 Lumens Competitor
Epson is setting the record straight on brightness. While others inflate their ratings, True Lumens gives you real performance — with white and colour brightness tested to strict ISO and IDMS standards. The result? Bright, sharp images that deliver exactly what’s promised. Portable, intelligent and uncompromising, the Epson EpiqVision Mini EF-22N shows you what projection should truly look like.

Brightness accuracy backed by ISO and IDMS standards
Epson projectors undergo rigorous testing according to ISO 21118:20202 and IDMS 15.4 standards:

Accurate lumen conversion:
Epson uses ISO 21118:2020 to measure White Brightness and IDMS 15.4 to measure Colour Brightness —
so the total light output is measured accurately. These standardised methods ensure that the
brightness you’re promised is the brightness you actually get.
Smart choices for bright, vibrant projections
Choosing the right projector goes beyond just looking at brightness claims. Many brands
advertise exaggerated lumen values, which can lead to disappointing
performance. To
ensure you’re getting the quality you expect, keep these
key factors in mind:
By focusing on these key aspects, you can invest in a projector that delivers true performance, reliability, and long-term value—whether for home entertainment, work presentations, or education.
Balanced brightness output
Make sure both white and colour brightness match your viewing needs for vivid, well-defined images.
Technology that matters
Epson 3LCD technology delivers consistent, true-to-life colours compared to 1-chip projectors.
Verified brightness
Look for projectors that adhere to ISO 21118:2020 and IDMS 15.4 standards, ensuring accurate brightness measurements.

Beware of misleading brightness claims
Not all lumen ratings are created equal. Some products may claim high brightness using “lumens” — but without following industry-recognised standards, those numbers can be inaccurate or misleading. Epson sets the standard for transparency and accuracy. White Brightness is measured using ISO 21118:2020, while Colour Brightness follows IDMS 15.4 — both internationally recognised benchmarks for reliable performance.
