Lamp Mode: Select the Lamp Mode you want to use in order to control the light output.
You can choose to run the lamp as bright as possible, you can power the lamp with a
specific wattage appropriate for the installed lamp or you can set a specific intensity
(brightness) to maintain. Keep in mind that higher lamp power settings can shorten lamp
life.
Use the lamp mode that best suits your brightness needs:
• Max Brightness: The lamp will always burn as brightly as possible, driven by 100% of
the power level rating for the installed lamp (1,000 Watts for the VX-40d and VX-60d or
1,200 Watts for the VX-50d and VX-80d). Keep in mind that the “maximum brightness”
for any lamp gradually diminishes with the “Intensity” option.
• Intensity: Brightness will remain close to a specified level for as long as possible. If you
select this option, enter a number representing the intensity level (brightness) you want
to maintain — the VX-40d/-50d/-60d/-80d automatically adjusts power as needed to
maintain this intensity as closely as possible.
This value and slidebar represents the current brightness of your lamp, decreasing over
time when you are operating in Max Brightness mode or at a specific Power level.
When you operate in Intensity mode, this value remains at the chosen Intensity setting
and cannot be adjusted.
To use “Intensity” mode, judge by eye (or use a meter) and set the level as desired for
your application. Over time, the projector will automatically increase the power supplied
to the lamp as needed to maintain the chosen intensity as closely as possible.
•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.
This slidebar and number indicates how many watts are applied to the lamp. You can
apply anywhere from approximately 60-65% of the maximum power intended for the
installed lamp up to 100% of the lamp rating. Set for the number of watts as desired,
keeping in mind that lower power levels produce dimmer images. When in either Power
or Max Brightness modes, the power level remains constant. Specifying a maximum
power level here is the same as operating in Max Brightness mode.
The Intensity value is not the actual lumen output, but rather a
correlated value only—1246 may represent 3500 lumens, for
example.
