Projector brightness is measured in lumens. For home theater projectors where ambient light is kept to a minimum, you'll need a minimum of 1500 lumens. For classrooms, conference rooms or rooms with windows, a projector with a minimum of 2500 lumens is best.
Now choosing lights: A typical well built LED downlight provide 80-110 Lumens per watt, letâs consider 100 lumens. So we need total of 20W LED light to get 2000 lumens and 150 Lux for our sample bed room. That means number of LED lights = 20w( total light)/5W(single light) = 4. If you consider florescent tube or CFLs, they provide 60 lumens per watt, but in all directions. So you need more than 35W to get sufficient lighting.
