expires, only the status information on the back of the projector will provide the
warning to replace the lamp.
NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2)
When a lamp warning message appears, press
message. The message will continued to appear upon power-up until you install a
new lamp.
LAMP LIMIT
Set to the number of hours you expect to log on the current lamp before
replacing it. This typically should match your lamp warranty, and can be affected by
what lamp mode you choose. When the lamp approaches the lamp limit, the Lamp
Message (if enabled) will appear upon power-up.
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 can reduce lamp
life significantly, as will other factors. Limit lamp strikes to what is necessary.
LAMP MODE
Set which you want to use in order to control the
light output in your application. Although there can be
exceptions, in most lamps the higher the light output or power
setting, the shorter the life span of the lamp.
Use the lamp mode that best suits your brightness needs. For
example, in a tiled application you may want to closely match brightness levels
between adjacent images—choose
set each individual intensity setting as necessary (see "Intensity", below). Or you
may simply always need as much brightness as possible, which will supply maximum
power to the lamp at all times—choose
Lamp modes are described below:
•
Max Brightness:
The lamp will always burn as brightly as possible, driven by
maximum power of 500W (Mirage 2000), 700W (Mirage 4000) or 1200W
(Mirage 6000). Keep in mind that the "maximum brightness" for any lamp
gradually diminishes with age—images will become dimmer over time. Its
current output level (note: not in lumens) appears in the "
•
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 (0-9999), not actual lumen levels
possible (0-5000, e.g.). See "
•
Power:
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.
POWER -
The number shown here indicates how many watts are applied to the lamp.
Set from 350-500 watts (Mirage 2000), 450-700 watts (Mirage 4000) or 800-1200
watts (Mirage 6000) as desired. Keep in mind that lower power levels produce
dimmer images. When in "
