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 Vision
140 or 1,200 Watts for
the Vision
150). 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 Vision 140/150 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% to 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.
HOW LONG CAN I MAINTAIN BRIGHTNESS? The Vision 140/150 can maintain your
“Intensity” setting until the required power reaches the maximum rating for the lamp. The
lower the setting, the longer it will take to reach this threshold and the longer you can
maintain the desired brightness. Keep in mind that once the lamp power reaches its
maximum wattage (see “Power,” above), this tracking is no longer possible. At this point, the
lamp will gradually begin to dim as usual, even though your original “Intensity” value will still
appear in the menu. To resume accurate tracking, reduce the intensity setting so that the
resulting “Power” value is less than its maximum—the lower the intensity, the longer it can
be maintained.
For example, a 1000-Watt lamp can be driven at no more than 1000 Watts. To produce
desired brightness at the screen, a new lamp would likely need less than this maximum
rating — perhaps 812 Watts (example only). Over time, however, the lamp requires more and
more current in order to generate the desired light, until eventually the lamp wattage
reaches its 1000-Watt maximum and the lamp power automatically levels off. At this point,
the tracking function terminates (that is, the power level stabilizes) and the lamp begins to
The Intensity value is not the actual lumen output, but rather a correlated
value only – 1246 may represent 3500 lumens, for example.
