Enter a checkmark for
LAMP MESSAGE
to enable a warning message that will appear
upon power-up when the lamp has reached the specified lamp limit and should be
replaced. Delete the checkmark to prevent display of this message—instead, when
your lamp expires, only the status display messages on the back of the projector will
provide the visual warning to replace the lamp.
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2)
When a lamp warning message appears, press to temporarily cancel the
message. The message will continue to appear upon power-up until you install a new
lamp.
Set
LAMP LIMIT
to the number of hours you expect to log on the current lamp before
replacing it. This will trigger a lamp message on-screen (if enabled).
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.
Set which
LAMP MODE
you want to use in order to control
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
Lamp Power
setting as necessary. Or
you may always want images to be as bright as possible—choose
Max Brightness
.
Keep in mind that higher lamp power settings can shorten lamp life.
Lamp modes are described below:
•
Max Brightness:
The lamp will always burn as brightly as possible, driven by
100% of the power level rating for the installed lamp (see Section 6,
Specifications ). Keep in mind that the “maximum brightness” for any lamp
gradually diminishes with age—images will become dimmer over time. Its
current output level appears in the “
Intensity
” option ( not in lumens).
•
Intensity:
Brightness will remain close to 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
that the intensity value is a correlation only and does not represent an actual
lumens level. See “
Intensity
” below.
•
Power:
The power supplied to the lamp will remain at your specified wattage
level. Once you select this option, enter the number of watts representing the
power level you wish to maintain. See “
Power
” below.
