Enter a check mark for Lamp MESSAGE to enable a warning message that appears upon power-up when the
lamp has reached the specified lamp limit and should be replaced. Delete the check mark to prevent display of
this message. Instead, when your lamp expires, only the status display messages on the back of the projector
provides the visual warning to replace the lamp.
NOTES: 1) It is recommended that the Lamp Message check box remain enabled. 2) When a lamp warning
message appears, press
appear each time you power-up until you install a new lamp.
Set the Lamp Limit to the number of hours you expect to log on the current lamp before replacing it. This
triggers 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 the 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
3-37. You can choose to run the lamp as bright as possible (i.e.,
always using maximum power-this is the default upon power up).
Alternatively, 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 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 110% of the power level rating for the
installed lamp. Refer to
lamp gradually diminishes with age and images become dimmer over time. Its current output level appears
in the "Intensity" option (not in lumens).
Intensity
Brightness remains 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.
Power
The power supplied to the lamp remains 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
The Power slidebar and number indicates how many watts are applied to the
lamp. You can apply anywhere from 60% to 100% of the lamp power rating.
Set for the number of watts as desired, keeping in mind that lower power levels produce dimmer images.
