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.

Lamp Usage Time = (x+y+z) hours, if Time used in Normal mode = x hours Time used in Eco mode = y hours Time used in SmartEco mode = z hours 2. Equivalent Lamp Hour= hours , if X= lamp life spec of Normal mode Y= lamp life spec of Eco mode Z= lamp life spec of SmartEco mode A' is the longest lamp life spec amoung X, Y, Z See "Setting Lamp mode" below for more information on Economic mode.
