Lamp information
Getting to know the lamp hour
When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by
the built-in timer. The method of calculating the equivalent lamp hour is as follows:
Lamp Usage Time = (hours used in
Normal
mode) + (hours used in
Economic
mode) + (hours used
in
SmartEco
mode)
Total (equivalent) lamp hour = 1.0 x (hours used in
Normal
mode) + 1.0 x (hours used in
Economic
mode) + 1.0 x (hours used in
SmartEco
mode)
You can get the lamp hour information on the
INFORMATION
menu.

Adjusts the lamp power automatically depending on the content brightness level
• 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.
