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
repeatedly reduces lamp life significantly, as do other factors, such as hot re-striking.
3) It is recommended that Lamp Limit not exceed the warranted lamp life, otherwise
a lamp could become dangerously fragile with overuse.

the light output (see Figure 3.26). You can choose to run the
lamp as bright as possible (i.e., always using maximum
power—this is the default). Alternatively, power the lamp
with a specific wattage appropriate for the installed lamp, or
set a desired intensity (brightness) to maintain. Although there are exceptions,
generally higher light output or higher power settings can shorten lamp life.
Use the lamp mode that best suits your brightness needs. For example, in a tiled
application you may want to precisely match brightness levels between adjacent
images—judge by eye and set each individual
