Lamp modes are as described below.
Max Brightness
The lamp always burns as brightly as possible, driven by 110% of the power level rating for the installed
lamp. Refer to
gradually diminishes with age and images become dimmer over time. Its current brightness output level
appears in the "Intensity" option.
NOTE:
Not in lumens.
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.
NOTE: "Max brightness" mode shortens lamp life. Avoid over-driving a lamp for extended periods.
Intensity
When the projector is operating in Max Brightness mode or at a specific Power level, the lamp brightness,
which naturally decreases over time, results in a decrease in image brightness. When operating in
"Intensity" mode, however, the image brightness remains at the selected intensity. The Intensity value
and slidebar represents the current brightness of your lamp.
NOTE:
The number shown for "intensity" is not the actual lumen output, but rather a correlated value only-9415
may represent 20,000 lumens, for example.
To use "Intensity" mode to set the level as desired for your
application, remembering that higher settings can significantly
shorten lamp life. Over time, the projector automatically increase the
power supplied to the lamp as needed to maintain the chosen intensity as closely as possible. This mode is
known as "Brightness Tracking" or "LiteLOC™".
Since power increases over time in this mode, prevent prolonged over-driving by checking the lamp power
readings periodically.
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" below.
The Power slidebar and number indicates how many watts are applied to
the lamp. You can apply anywhere from 75% of the maximum power
intended for the installed lamp up to an "over-drive" that exceeds the
maximum rating by approximately 10%. 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, and will shorten lamp life.
NOTE:
Power level can be set only if the lamp is in "Power" mode.
