The power supplied to the lamp will remain at a desired watt level
throughout the life of the lamp. Once you select this option, enter the
number of watts representing the power level you wish to maintain. See
"
" below.
The number shown here indicates how many watts are applied to the
lamp. Set from 350-500 watts as desired, keeping in mind that lower power
levels produce a dimmer image while extending lamp life.
NOTES: 1) Power level can be set only if the lamp is in "power" mode. 2) If you
are in "Intensity" mode, the power level value will automatically increase over
time as necessary to maintain the desired brightness, until it reaches 500W.
The number shown here usually varies with the brightness of your
lamp. However, if you are currently operating in "

application, remembering that higher settings can significantly shorten lamp life.
Over time, the projector will automatically increase the power supplied to the
lamp as needed to maintain the chosen intensity to within 10% of the setting.
This is called brightness "tracking".
Keep in mind that once the lamp power has reached its maximum of 500 watts
(see "

will gradually begin to dim as usual, even though your original "

cannot be maintained. For matching intensity over in tiled images, choose an
intensity setting that enables all lamps to operate at less than 500 watts.
NOTES: 1) Lamps become more stable over time, thus a specific intensity is
more easily maintained as the lamp ages 2) Intensity can be set only if the lamp
is in "intensity" mode 3) Intensity will not exceed the output of Max Brt mode.
