LAMP LIMIT – Enter the number of hours you expect to log on the current lamp before
replacing it. 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.
LAMP MODE - Use the pull down list to select the Lamp
Mode (power level) of the projector. This option gives you
the ability to control the light output of the projector.
Although there are some exceptions, typically the life span
of the lamp is shortened the higher you set the light output or power setting of the
projector.
•
Max Brightness: Select this option when you want the lamp to always burn as
brightly as possible. The Power option (slidebar) in the Lamp menu will read
as 120W in Single or Dual Lamp mode. Keep in mind that the maximum
brightness for any lamp gradually diminishes with age and the image becomes
dimmer over time.
•
Power: Select this option to set the amount of power (in watts) supplied to the
lamps (single or both). The power level remains constant throughout the life
of the lamp.
POWER – Use the Power slidebar (Figure 3.23.) to set the power level (in watts) that
will be applied to each of the lamps during operation. Power can be set at 100W –
120W for each of the lamps. When you are operating in Single Lamp mode, power is
increased or decreased incrementally for the selected lamp. In Dual Lamp mode,
power changes for alternating lamps (also in increments) until the desired power level
is reached for both lamps. The power level you select will remain constant throughout
operation. In general, dimmer images are produced when power levels are low.
Specifying the maximum power level (120W) in this mode is the same as operating in
Max Brightness mode.
Figure 3.23.
LAMP OPERATION - One of the key features of the projector is that it can be operated
with one or two lamps on. From the pull down list, select the lamp operation mode
you want to operate the projector in. Dual Lamp is the default.
