LAMP MESSAGE
Enter a checkmark for
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
message. The message will continued to appear upon power-up until you install a
new lamp.
LAMP LIMIT
Set 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). Recommended
limits for each of the four lamp sizes are listed in Table 3.5 later in this section.
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 warranted lamp life, otherwise a lamp could become dangerously fragile with
overuse.
LAMP MODE
Set which you want to use in order to control
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
you may simply always want images to be as bright as possible—choose
Brightness
. Always keep in mind that higher lamp power settings shorten lamp life.
Lamp modes are described below:
•
Max Brightness:
The lamp will always burn as brightly as possible, driven by
110% 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 (note: not in lumens) appears in the "
NOTE: "Max brightness" mode shortens lamp life. Avoid over-driving a lamp
for extended periods.
•
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 "
