你这个说法靠谱
这里有更详细的解释
You can find the estimated (SI) lumen output of a projector by dividing its ANSI lumen output by between 0.04 and 0.06 , depending on the manufacturer (who may provide this value). But it's important to note that doing so is a bit artificial, as they're measuring two different things. SI lumens are a more general representation of how bright a light source is, while ANSI lumens are how bright that light is when it makes its way out of the projector and onto a surface.
