NOTES:
1)
If you change modes over the life of a lamp, the lamp limit you
originally expected may no longer be possible.
2)
Turning the lamp on and off
repeatedly reduces lamp life significantly, as do other factors, such as hot re-striking.
3)
It is recommended that Lamp Limit not exceed the warranted 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 (see Figure 3.26). You can choose to run the
lamp as bright as possible (i.e., always using maximum
power—this is the default). Alternatively, power the lamp
with a specific wattage appropriate for the installed lamp, or
set a desired 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
you may always want images to be as bright as possible—choose
Max Brightness
.
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% to 100% of the lamp power 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
P
ower
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.
