Replacing the Lamp
The projection lamp typically lasts for about 1000 hours of use. It is
time to replace the lamp when:
■ The projected image gets darker or starts to deteriorate.
■ The lamp warning light is red, flashing red, or flashing
orange.
■ The message LAMP REPLACE appears on the screen when the
lamp comes on (after about 900 hours of use). To maintain
projector brightness and image quality, replace the lamp as soon
as possible.
Contact your dealer or call EPSON at (800) 873-7766 in the United
States and Canada for a replacement lamp. Request part number
