Light source information

Getting to know the light source hour
When the projector is in operation, the duration (in hours) of light source usage is automatically
calculated by the built-in timer. The method of calculating the equivalent light source hour is as follows:
Light source Usage Time = (hours used in Normal mode) + (hours used in Economic mode) +
(hours used in Dimming mode) + (hours used in Custom mode)
Total (equivalent) light source hour = 1.0 x (hours used in Normal mode) + 1.0 x (hours used in
Economic mode) + 1.0 x (hours used in Dimming mode) + 1.0 x (hours used in Custom mode)
To obtain the light source hour information:
1. Go to Advanced Menu - Settings > Light Settings and press OK. The Light Settings page
appears.
2. Press to select Light Usage Time and press OK. The Light Usage Time information is
displayed.
You can also get the light source hour information on the Information menu.

• The apparent brightness of the projected image will vary depending on the ambient lighting conditions, selected
input signal contrast/brightness settings, and is directly proportional to projection distance.
• The light source brightness will decline over time and may vary within the light source manufacturers
specifications. This is normal and expected behavior.
