Many projectors on the market have marked brightness. The strange thing is that some projectors are very cheap but have thousands of lumens, but some expensive projectors only have thousands or hundreds of ANSI lumens. Understand, the brightness of a projector is a science. In order to prevent everyone from entering the pit, let me explain to everyone what the lumen of the projector is?
In fact, there is a slight difference between lumens and ANSI lumens. Lumen is the unit of luminous flux, while ANSI lumens is the international standard unit for projectors to express luminous flux. Lumen usually refers to the brightness of the projector. The higher the lumen value of the projector, the higher the brightness.
So the brightness standard we often use is ANSI lumens. When measuring, under certain conditions, nine points are used to measure the average brightness of the nine points on the projection screen. This brightness value is relatively low, usually much lower than the brightness of thousands of lumens that are said on the market. But it is also much more accurate. For this reason, many manufacturers label lumens instead of ANSI lumens.
Actually in the daily movie watching process. ANSI lumens is the brightness standard we use most often. Therefore, what indicates this brightness is actually the real brightness of the projector, and it is also the most reliable brightness!
