Projector Calculations [2]

  • This time I went for the native 16:10 model EB-G6250. The calculator does not have this model, so I used the similar Powerlite Pro G6050W.
  • Screen Gain 1.0
  • Throw distance 20 metres
  • Calculator lists 8 lenses but only 6 of these are current with the G6250 model. Of these only three have the range required to work at 20 metres.
  • Long Throw Lens ELPLL06
    • 2.3 metres high, 4.3 metres diagonal, 3.6 metres wide.
    • Throw range 17-24 metres.
    • Seating distance range 4.7-21.8 metres.
    • Image brightness 134 nits.
  • Middle Throw Lens ELPLM04
    • 4.7 metres high, 8.8 metres diagonal, 7.5 metres wide.
    • Throw range 16-26 metres.
    • Seating distance range 10-45 metres.
    • Image brightness 30 nits.
  • Middle Throw Lens ELPLM05
    • 3.2 metres high, 6.1 metres diagonal, 5.1 metres wide.
    • Throw range 16-26 metres.
    • Seating distance range 7-30 metres.
    • Image brightness 61 nits.
Based on the above data the recommended choice of lens would be the ELPLL06.
