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 reduces lamp life
significantly, as do other factors. 3) It is recommended that Lamp Limit not exceed the
expected lamp life, otherwise a lamp could become dangerously fragile with overuse.

the light output. You can choose to run the lamp as bright as
possible (i.e., always using maximum power—this is the
default upon power up) or you can power the lamp with a
specific wattage appropriate for the installed lamp or you can set a specific 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

as needed to maintain this intensity as closely as possible. Note that the intensity
