In an attempt to increase awareness about the performance of different projector brands, Epson Philippines held a media briefing on Tuesday, Sept. 10, to preach what it claimed as the “truth” behind projector technologies.

The Epson briefing, held at its headquarters in Ortigas, Pasig City, focused on the color light output (CLO) that determines the so-called “color brightness” in projectors.

CLO or color brightness is a scientific global standard that measures the luminance of the colors red, green, and blue. The metric was specifically developed to measure significant differences in color brightness performance among different projector models and brands to provide consumers with fair and accurate information.

Toshimitsu Tanaka, president and country manager of Epson Philippines, recalled that in 2009, the National Institute of Science and Technology or NIST publicly brought into wider public attention the lack of reliable color information for projector users and buyers.

NIST also pointed out that white light brightness alone does not give a projector’s color performance. A third party study also showed that more than 70 percent of projector buyers are not aware that a projector’s brightness — measured in lumens — only provides white light output and not color brightness.

After extensive evaluation, in June 2012, the International Committee for Display Metrology (ICDM) finally published CLO as an official measurement for color brightness.

Since then, Tanaka said different projector technologies have tried to adapt to this new global metric with varying levels of success, the results of which can be found on third-party evaluations of different projector brands.

According to Amy Kwa, Epson Singapore assistant manager for visual instruments, the influx of high-definition, color-rich media, white light output is simply not enough to convey the brightness story.

“Color Light Output, or simply color brightness, can give customers the complete picture in getting the best projector performance,” Kwa said.

She explained Epson’s 3LCD or 3-chip technology enables its projectors to bring luminance of the colors red, green, and blue as compared to other projectors that use only a single chip.

“Color brightness is an area where Epson’s 3LCD projectors really shine,” Tanaka said. “Most users determine a projector’s capability to successfully present vibrant images with the projector?s brightness, measured in lumens. In general, the higher the number of lumens, the brighter the projector.”

Tanaka, however, said the widely-used lumens specification measures only white light, and according to a recent study from TFC Info Associates, more than 70 percent of projector buyers do not know this fact.

Epson offered a few tips to consumers such as looking for separate color and white brightness specifications. The Japanese tech firm said buyers should also be vigilant, saying many manufacturers do not disclose that their projectors are only 1/3 as bright when measuring color.

Also during the briefing, Epson showcased two of its latest projectors, the EB-435W and EB-X12.

The EB-435W is a short-throw projector with white light output of 2500/3000 lumens, and color light output of 2500/3000 lumens.

The EB-X12, meanwhile, has white and color light outputs of 2800 lumens designed for school and office use.
