to the number of hours you expect to log on the current lamp before
replacing it. This typically should match your lamp warranty, with actual lamp life
varying widely depending on your application and whether or not you require
maximum output from the lamp. When the lamp approached the lamp limit, the
Lamp Message (if enabled) will appear upon power-up. See Lamp Mode, below.
NOTES: 1) If you change modes over the life of a lamp, the lamp limit you originally
expected may no longer be possible. 2) Turning the lamp on and off can reduce lamp
life significantly, as will other factors. Limit strikes to what is necessary.

lamps, the higher the light output or power setting, the
shorter the life span of the lamp.
Use the lamp mode that best suits your brightness needs. For
example, in a tiled application you may want to closely match brightness levels
between adjacent images—choose
set each individual intensity setting as necessary (see "Intensity", below). Or you
may simply always need as much brightness as possible—choose

maximum power of 500W in this model. Keep in mind that the "maximum
brightness" for any lamp gradually diminishes with age—the image will
become dimmer over time. Its current output level appears in the "
option (not in lumens).
•
Intensity:
Light output will remain at a specified level for as long as possible.
Once you select this option, enter a number representing the intensity level
(brightness) you wish to maintain—the projector will automatically adjust
power as needed to maintain this intensity as closely as possible. Note this
value is a correlation only (0-9999), not actual lumen levels possible (0-1500,
