LAMP S/N (read-only) is the serial number recorded for the current lamp. When you
install a new lamp and enter its serial number, the number will appear here.
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
Exi t
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 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.
Set which
LAMP MODE 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
Lamp Power setting as necessary. Or if
you want images to be as bright as possible—choose
Max Brightness. Always 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.
