Brightness (Lumens)

• 2000 lumens and less - Suitable for small room with low light. Can you afford to turn off room light and let people take note in the dark?

• 2000 to 3000 lumens - Suitable for most business conference room and classroom presentation.

• 3000 to 4000 lumens - Suitable for large conference rooms and classrooms. More flexibility in terms of ambient room light.

• 4000 lumens and up - Suitable large board rooms, conference rooms, training rooms, auditoriums with large number of audience.

• How large is the audience size? You may be able to get away with small projector with less than 2000 lumens for small audience in a small room.

•  How is the room condition? Is the room dark enough? Can you turn off the light or block off sun light? Does your audience need to take note? Sometime you have no choice but have to go with a brighter projector even for small audience size in a small room.

• What content is being display? You need some room light for business presentation and training with lot of text.
