Epson held an event last September 10 to show and inform the public regarding the importance of CLO metric when buying a new projector. This is to help consumers make a smart and informed decision.
What is CLO?
When watching movies, vibrant images matter a lot. In order to accurately and scientifically measure the luminance of the primary colors Red, Green, and Blue, the National Institute of Science and Technology (NIST) created CLO. Color Light Ouput (CLO) is basically “the metric that determines the Color Brightness in projectors.”
Lumens vs. CLO
When buying a projector, people usually check the “lumens”. Lumens is a type of measurement in order to tell the projector’s capability to “successfully present vibrant images with the projector’s brightness.” Generally, the higher the number of lumens the brighter the projector.
For example: People would be willing to pay more money on a projector that has 3000 Lumens compared to a projector that has 2600 Lumens.
Now, the problem with simply looking at lumens is that it only measures white light. And the sad truth is, according to a recent study done by TFC Info Associates, around 70% of projector buyers are not aware of this.
So technically speaking, Lumens is not the be-all and end-all specification that consumers should check when buying projectors.
In order to know the true color brightness, consumers must look at CLO.
Color Brightness of Epson Projectors
Epson is actually one of the pioneers in the industry to adopt the CLO metric. This is to ensure that consumers can make an informed decision when buying projectors. The reason why Epson projectors perform a lot better when it comes to color brightness is because of their proprietary 3LCD technology.
3LCD versus 1-Chip DLP
3LCD means that a projector uses three separate LCD chips for the colors Red, Green, and Blue. Because this technology uses three chips, the color that it delivers is full, vibrant, and more accurate.
Now, the 1-Chip projector, as the name suggests only uses one chip. So, in order to project the colors red, green, and blue, the projector has to use a color wheel.
Because of this, 1-Chip projector displays darker hues of colors.
How to find a projector’s Color Brigthness?
If you’re out to buy a new projector, make sure to not only check the Lumens. Specifically ask for the separate Color Brightness spec. Usually, many manufacturers would only show the Lumens.
If the salesman doesn’t knowm or the actual packaging of the projector does not indicate the Color Brightness measurement, you can actually check the color brightness rating of a projector at www.colorlightoutpout.com.
Here’s a quick video that can guide you on how to choose the right projector:
As they say, knowing is half the battle. So, when buying projectors or even any type of electronics, it’s best to get the facts straight. This ensures that you get the most value from your hard-earned money.
