Epson Settles Lawsuit with AAXA on Deceptive Brightness Claims

Epson states that going forward AAXA will use the ISO 21118 standard to measure a projector’s white brightness levels.

Epson has reached a settlement with AAXA for a lawsuit highlighting deceptive advertising practices surrounding the company’s P6U projector model.

Under the settlement terms, AAXA will correct previously misstated white brightness specifications worldwide for the P6U projector, reducing 1,100 Lumens down to 500 Lumens, to accurately reflect brightness. Moving forward, AAXA will use ISO 21118, the internationally recognized standard for measuring a projector’s white brightness. Epson stresses that white brightness measured in Lumens using ISO 21118 is a critically important specification relied on by consumers when making a projector buying decision.

“When projector brands use the same, internationally developed and published standards, it protects consumers and establishes trust within the industry,” says Mike Isgrig, vice president, consumer sales and marketing, Epson America. “AAXA’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.”

Epson Settlement with AAXA Will More Accurately Reflect Performance Capabilities

The initial complaint against AAXA was made as part of Epson’s efforts to ensure the implementation of internationally recognized and accepted brightness standards are used by brands to help consumers make informed purchasing decisions. The corrected specifications states Epson, are now accurate white brightness claims, benefiting consumers, the retail channel, and the entire home electronics industry.

Unfortunately, Espon continues, there has been an influx of projector brands that are providing misleading brightness claims. Epson warns dealers and consumers to be wary of misleading metrics listed as “lux,” “LED lumens,” or “lamp brightness” that fail to follow standardized methodology to impact a consumer’s ability to compare performance of projectors, especially when shopping on Amazon and other online marketplaces.

Epson points out that measurement for projectors is defined by internationally recognized standards groups, including the International Organization for Standardization (ISO) and the International Committee for Display Metrology (ICDM). The ICDM publishes the Information Display Measurement Standards (IDMS) where methodology for measuring projector color brightness is defined. The ISO standard that defines projector white brightness is ISO 21118. In addition, the U.S. member body for ISO—ANSI (American National Standards Institute)—has adopted ISO 21118, underscoring ISO 21118 as the industry standard for White Brightness.

The company emphasizes that when these standards are followed, there is zero ambiguity regarding how projector brightness is properly measured, advertised and compared.
