new one as soon as possible, even if it is still working.

been used, the lamp may become darker or stop working before
the lamp warning message appears. You should always have a
spare lamp ready incase it is needed.

When replacing the lamp because it has stopped illuminating, there
is a possibility that the lamp may be broken.
If replacing the lamp of a projector which has been installed on the
ceiling, you should always assume that the lamp is broken, and you
should stand to the side of the lamp cover, not underneath it.
Remove the lamp cover gently.
