Why is the lamp replacement
light illuminated on my
If the “Lamp Replace” light on your
projector appears, this is a warning
that the bulb is nearing “end of life”.
The bulb could last several weeks to
several months. Order a replacement
bulb, if you do not have a spare. If
you do have a spare, the bulb will
need to be replaced either when it
goes out or the display is so dim it
impairs the ability to view the
projection. Contact your reseller or
Promethean if this happens.
