Using Lamp Power - Christie CP2000-SB User Manual

HOW LONG CAN I MAINTAIN BRIGHTNESS?
Software can maintain a LiteLOC™ setting until the required power exceeds the maximum rating for the lamp
(2.0, 3.0, 4.5, or 6.0 kW) by approximately 10%. The lower your LiteLOC™ setting, the longer it will take to
reach this over-drive threshold and the longer you can maintain the desired brightness.
For example, a 6000 watt lamp (6.0 kW)
can be safely driven at no more than 6600
watts. To produce 14 fL at the screen, a
new lamp would likely need less than this
maximum rating-perhaps 5120 watts
(example only). Over time, however, the
lamp will require more and more current in
order to produce the 14 fL, until eventually
the lamp wattage reaches its 6600
overdrive maximum, and the power to it
automatically levels off. At this point, the
LiteLOC™ function terminates (i.e., the
power level stabilizes), the lamp will begin
to dim normally with age, and the light
output gauge will begin falling. Either reduce your LiteLOC™ setting or replace the lamp.

Using Lamp Power

To change to a different power level, simply enter a new Lamp Power percentage at any time. This will
override (and temporarily disable) any LiteLOC™ setting that may be in effect:
1. Set Lamp Power to apply a specific percentage of power appropriate for the installed lamp. LiteLOC™
will automatically be disabled.
2. Brightness will change accordingly, new values will appear for amps, volts and watts, and the blue light
output bar graph will move above or below the LiteLOC™ line, depending on the new setting.
As the lamp ages and becomes more inefficient, your chosen power level will gradually produce less and less
light output. To return to the previous LiteLOC™ setting, enable the LiteLOC™ checkbox.
NOTE: When re-enabling LiteLOC™ from a current brightness level that is more than 10% brighter or
dimmer than the LiteLOC™ setting, the recovery will be immediate. When re-enabling LiteLOC™ from a
brightness setting that differs by only 10% or less, the recovery will be gradual.
