miniprojektor

hej

jeg skal have købt en miniprojektor som kun skal bruge til noget PowerPoint fremvisning. Den skal være nem at have med og jeg har kigget på forskellige modeller, bla. Qumi q5
Med når de har 500 ANSI lumen, vil de så gi et læsbar billede i dagslys el. er det kun noget der dur til mørke rum!?
i så fald hvor går grænsen i lumen hvis den bare skal køre en præsentation?

• Less than 2000 lumens. Typically small and highly portable, these are the lowest light output projectors available today, and they are typically the least expensive. For display of training videos or still photography in a darkened room, projectors in this category may be perfect for your needs. Keep in mind that the low light output means that you will want to make your presentations in a dark or dimly lit room so that the image on the screen is not washed out by ambient room light.
• 2000 to 3000 lumens. This lumen range is a step up in performance and price. These machines are suitable for normal business conference room and classroom use. Presentations should be done with the room lighting reduced somewhat for best screen viewing. A completely dark room is usually not necessary.
• 3000 to 4500 lumens. This represents the high-performance range of the portable and semi-portable projectors. Products in this class are suitable for large conference rooms and classrooms. They offer more flexibility in terms of ambient room light, since the image is bright enough that a reasonable amount of room light can be tolerated without washing out the image. They also offer more flexibility in terms of audience size, since they produce enough lumens to properly light a larger screen.
• 4500 lumens and up. These ultra-bright projectors are in several performance classes unto themselves, ranging from 4500 lumens up to 12000 lumens or more. Prices of these products also cover a wide range depending on other performance characteristics. They are used in a variety of large venue applications, including board rooms, conference rooms, training rooms, auditoriums, churches, concerts, nightclubs, and so forth.
