A daylight projector is key if you are working in a bright room. Often, meeting rooms, conference rooms or living rooms are difficult to darken. In this case, the light intensity of a daylight projector is crucial. For a really bright room you need a light output of 5000 lumens or more. With this light output, a projector can usually perform well in a bright room. However, it is still no outdoor projector. A projector for outside needs an even higher light output. However you should make sure that the environment is darkened, for example, with a gazebo that stands on the terrace. Without this to block out some sunlight, a projector would provide a barely recognisable image in direct sunlight.
