Vidikron Vision 150 User Manual

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.
