Epson announced it has reached a settlement with Dangbei, an Amazon seller, for its recent lawsuit highlighting deceptive advertising practices.
Under the settlement terms, Dangbei agreed to correct previously misstated white brightness specifications worldwide for the Mars Pro projector, reducing 3,200 lumens down to 1,800 lumens to reflect accurate brightness claims.
In addition, Dangbei agreed to use internationally recognized standards (such as ISO 21118 standard for measuring projector white brightness) moving forward. White Brightness measured in Lumens is a critically important feature used by consumers when making a projector buying decision.
“When projector brands use the same, single internationally developed and published standards, it is consumers who are the winners,” said Mike Isgrig, Vice President, Consumer Sales and Marketing, Epson America. “Dangbei’s commitment to use internationally published and accepted standards (such as ISO 21118 for white brightness) moving forward for their entire product line will provide accurate white brightness information for consumers to make informed buying decisions.”
The initial complaint was made as part of Epson’s efforts to ensure the implementation of internationally recognised and accepted brightness standards are used by brands to help consumers make informed purchasing decisions. The corrected specifications are now accurate brightness claims, benefiting consumers, the retail channel, and the larger industry.
Epson cautions shoppers to be wary of misleading metrics listed as “Lux,” “LED lumens,” “CVIA,” or “Lamp Brightness” that fail to follow standardised methodology and therefore materially impacts a consumer’s ability to compare performance of projectors, especially when shopping Amazon and other online marketplaces.
Measurement for projectors is defined by internationally recognised standards groups, including the International Organization for Standardisation (ISO) and the International Committee for Display Metrology (ICDM).
The ICDM publishes the Information Display Measurement Standards (IDMS) where methodology for measuring projector colour brightness is defined. The ISO standard that defines projector white brightness is ISO21118:2020. When these standards are followed, there is zero ambiguity regarding how projector brightness is properly measured, advertised and compared.
