How to calculate the amount of light required

The basic formula to calculate this theoretical light requirement is:

 Lumens (L) = Average Screen Brightness desired (average fL)

X Screen Area (sq ft)

• Givenagoodlightdistribution,the“AverageScreenBrightness”

canbeestimatedbymultiplyingthecenterbrightnessdesiredby

0.95.Generallyacceptedpracticeforthetargetcenterbrightness

is:14fLfor2Dand4.5fLfor3D(lightmeasurementtakenthrough

3Dglasses).

 Afteryouhavethe“Lumens”numberyouwoulddivideitbyall
