lamp modes are described below:
Max brightness:
•
The lamp will always burn as brightly as possible, driven by 100% of the
power level rating for the installed lamp (see
Section 6, Specifications). Keep in mind
that the “maximum brightness” for any lamp gradually diminishes with age — images will
become dimmer over time. its current output level appears in the “Intensity” option (not in
lumens).
Intensity:
• Brightness will remain 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. See “Intensity” below.
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. See “Power” below.
POWeR – 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.
nOTes: Power level can be set only if the lamp is in Power mode.
InTensITY – 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 are operating in
“Intensity” mode this value remains at the original “Intensity” setting chosen and cannot be
adjusted.
nOTe: The number shown for “intensity” is not the actual lumen output, but rather a correlated
value only — 1246 may represent 3500 lumens, for example.
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.
HOW lOnG Can I MaInTaIn bRIGHTness? Software 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.
