The value varies depending on the lens.*3 Measurement, measuring conditions, and method of notation all comply with ISO/IEC 21118:2012 international standards.*4 The value of the light output at the center region of the projected image is extracted based on the light output measurement method defined by theISO/IEC 21118:2012 international standards.*5 When the lens ET-DLE055 is used, the maximum size is 5.08 m (200"). When the lens ET-DLE030 is used, the maximum size is 2.54 m (100") to8.89 m (350").*6 Average value. Weight varies for each product.*7 When using the projector at an altitude lower than 2 700 m (8 858') above sea level, and the operating environment temperature becomes 35 °C(95 °F) or higher, the light output may be reduced to protect the projector. When using the projector at an altitude between 2 700 m (8 858') and4 200 m (13 780'), and the operating environment temperature becomes 25 °C (77 °F) or higher, the light output may be reduced to protect theprojector.
