Epson and Anker Settle Projector Brightness Case Over Misleading Lumen Claims

Epson has announced that it has reached a settlement with Anker for its recent lawsuit highlighting deceptive advertising practices of Nebula. 

Nebula is a leading lifestyle projector brand marketed by Anker. Under the settlement terms, Anker has agreed to relabel the lumen ratings on three of its Nebula Cosmos projector models from previously misstated lumens to reflect more accurate brightness claims to benefit consumers.

The initial complaint was made as part of Epson’s ongoing efforts to ensure that internationally recognized and accepted brightness standards are used by brands to help consumers make informed purchasing decisions.

“Our goal is straightforward – to ensure consumers have accurate information when making purchasing decisions,” said Mike Isgrig, vice president, consumer sales and marketing, Epson America. “Anker’s actions to correct lumens claims for several of their projectors according to industry measurement standards helps to ensure consumers know what to expect in projector performance. The consistent use of standardized metrics ultimately impacts the entire marketplace positively, ensuring consumers have the right projector for their viewing needs.”

Anker will correct lumens specifications for the Nebula Cosmos Laser 4K (D2350) from 2,400 Lumens to 1,840 Lumens, Nebula Cosmos Laser (D2341) will be reduced from 2,400 Lumens to 1,840 Lumens  while the Nebula Cosmos (D2140) will be reduced from 900 Lumens to 810 Lumens.

In a statement issued on its Nebula website, Anker also says that it has “officially adopted the ANSI Lumen specification (ANSI IT7.228-1997)” and would apply this to all future Nebula projectors. It also adds that it will “update its product listings, marketing materials, and where applicable, packaging” to reflect accurate ANSI numbers.

Epson saud it ”cautions shoppers to be wary of misleading metrics listed as “Lux,” “LED lumens” or “Lamp Brightness” that fail to follow standardized methodology and therefore materially impacts a consumer’s ability to compare performance of projectors. 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 and white brightness separately are defined.

The ISO standard that defines projector measurement methodology is ISO21118:2020. When these standards are followed, there is zero ambiguity regarding how projectors are to be properly measured and compared.
