other factors. 3) It is recommended that Lamp Limit not exceed the expected lamp life, otherwise a lamp could
become dangerously fragile with overuse.
Set which LAMP MODE you want to use in order to control the light output. You
can choose to run the lamp as bright as possible (i.e., always using maximum
power — this is the default upon power up) or you can power the lamp with a
specific wattage appropriate for the installed lamp or you can set a specific
intensity (brightness) to maintain. Although there are exceptions, generally higher light output or higher power
settings can shorten lamp life. Use the lamp mode that best suits your brightness needs. For example, in a tiled
application you may want to precisely match brightness levels between adjacent images — judge by eye and set
each individual Lamp Power setting as necessary. Or if you want images to be as bright as possible — choose Max
Brightness. Always keep in mind that higher lamp power settings can shorten lamp life.
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. NOTE: 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.
