CCB lumens is a new brightness concept recently proposed by a well-known brand XGIMI in China. Is it possible to convert between CCB lumens and ANSI lumens? 1 CCB lumen is equal to how many ANSI lumen?
How to convert CCB lumens and ANSI lumens
Since CCB lumens is a new concept, to convert it with the industry standard ANSI lumens, a reference is needed, and XGIMI H3S is a good reference because the newly released H5 color brightness of XGIMI is higher than the previous one. The replacement of H3S has increased by 27%. Converted from the 1400 CCB lumens of H5, the XGIMI H3S is approximately equal to 1100 CCB lumens, and when converted to 2200 ANSI lumens, it can be found that 1 CCB lumens is approximately equal to 2 ANSI lumens. From this, it can be inferred that the brightness of the XGIMI H5 is actually 2800 ANSI lumens, which is not as good as the 3200 ANSI lumens of the laser projection Dangbei Mars Pro, and it is also much more expensive than the Dangbei F5 with the same brightness.
Can CCB lumens be a new brightness standard?
If there is a conversion between CCB lumens and ANSI lumens, can it be the new industry standard? After all, the official who launched this concept said that it includes the control of indicators such as the color temperature, color accuracy and image uniformity of the projection screen, and at the same time strictly requires the color temperature, D65 color temperature when needed, and the red, green, and blue three original points are Rec709 color point , At the same time, the measurement method has four more test points than the nine-point test, and the thirteen-point test method is used.
I personally think that CCB cannot be used as an industry standard, because industry standards not only need to be recognized by the public, but also need to be certified by industry associations. In terms of authority, currently only ANSI lumens and ISO lumens are the most authoritative and can be regarded as the industry. As far as brightness is concerned, users should still focus on ANSI lumens and ISO lumens. We have projector calculator for you to configure different industry accepted brightness units. But CCB lumens are only applicable to the XGIMI brand.
In order to become the industry standard, CCB lumens need to be certified by international organizations. For now, it’s just that XGIMI officials are singing a one-man show. If you want to know the brightness of XGIMI products, you can measure it by yourself with an illuminometer, or you can get the ANSI lumen value through a 1:2 lumen conversion.
