Timing of replacing the lamp
When the
Lamp indicator
lights up or a message appears suggesting it is time to replace the lamp,
please consult your dealer or go to
http://www.BenQ.com
before installing a new lamp. An old lamp
may cause a malfunction in the projector and in some instances the lamp may explode.
For Time used in each lamp 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 Lamp hour manually, it will probably have deviation from the value shown in OSD
menu since projector system calculates Time used for each lamp mode in "Minutes" then rounds down to an integer
in hours shown in OSD.

Economic
Lowers brightness to extend the lamp life and decreases the fan noise
SmartEco
Adjusts the lamp power automatically depending on the content brightness level while
optimizing display quality
• 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 lamp brightness will decline over time and may vary within the lamp manufacturers specifications. This is
normal and expected behavior.
• The
LAMP indicator light
and
TEMPerature warning light
will light up if the lamp becomes too hot. Turn
the power off and let the projector cool for 45 minutes. If the Lamp or Temp indicator still lights up after turning
the power back on, please contact your dealer. See
