Light source information

Getting to know the light 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 hour is as
follows:
1. Light Usage Time = (x+y+z) hours, if
Time used in Normal Mode = x hours
Time used in ECO Mode = y hours
Time used in Dynamic Mode = z hours
2. Equivalent Light Hour =
A'
  
--- -
= +
X
X= light source life spec of Normal Mode
Y= light source life spec of ECO Mode
Z= light source life spec of Dynamic Mode
A' is the longest light life spec among X, Y, Z.
For time used in each light source mode shown in OSD menu:
• Time used is accumulated and rounded down to an integer in hours.
• When time used is less than 1 hour, it shows 0 hours.
When you calculate Equivalent Light Hours manually, it will probably have deviation from the value shown
in OSD menu since projector system calculates time used for each light source mode in "Minutes" then
rounds down to an integer in hours shown in OSD.
To obtain the light source information:
Go to Advanced Menu - System > Light Source Information and press OK. The Light Source
Information page appears.
You can also get the light hour information on the Information menu.
Extending light source life
• Setting the Light Source Mode
Go to Advanced Menu - Game & Pic. > Advanced Color Settings > Light Source Mode and
press / to select a suitable light source power from among the provided modes.
Setting the projector in ECO Mode, or Dynamic Mode extends light life.
