* The maximum power of the lamp power supply is restricted to 3000W ± 100W.
Christie provides a wide lamp power range to give flexibility in meeting different exhibition configurations.
However, older lamps may not always strike at the lowest power settings. For more details, see
Specifications. For more information on setting lamp power, see
While it is common recommended practice in cinemas to run lamps only within their specified current ranges,
we allow for an adjustment on the power supplies that allow operation of the lamps much lower than their
specified wattage and up to 10% above. This is done for 2 reasons. Under-current operation is sometimes
needed in systems that are normally operating both 2D and 3D operational modes and for 2D presentations.
While there can be ignition problems if the current is dramatically lower than the specification, such problems
don't develop until the lamp has aged significantly. Over-current operation is used for LampLOC™ purposes.
As a lamp ages, the voltage decreases. This allows for higher current to be used during the latter part of a
lamp's life and therefore extend the usability of the lamp.

Control Description
1: Power % Indicates the percentage of power to supply to the lamp and automatically over-
rides the LiteLOC™ setting that may be in effect. Refer to Table 3.17 for the
valid Lamp Power ranges for specific lamp types. Adjusting the Lamp Power %
causes the bar graph to rise or fall as lamp power increases or decreases. The
LiteLOC™ red line and Lamp Status values will not change unless the Set
Target button is clicked. This defines a new LiteLOC™ setting and selects the
Enable LiteLOC™ check box. Lamp Power % is enabled only when the
Enable LiteLOC™ check box is clear.
2: Enable Select the Enable LiteLOC™ check box to use LiteLOC™ for the current
channel. When LiteLOC™ is enabled, the last saved target value is used.

3: Light Meter Clicking the Set Target button automatically enables LiteLOC™ (Enable
LiteLOC™ check box selected) and maintains the current brightness level

4: Amps,
Lamp current in amperes, lamp voltage in volts, lamp power in watts, approxi-
mate Foot Lamberts reading on the light sensor (assuming a calibration was per-
Volts, Watts,

automatically from the projector.
5: Text Region
Shows the current light sensor reading in arbitrary units-of -measure and does
not represent actual lumens or fL. This read-only value is updated automatically
from the projector.
6: Light Bar
This visual representation of the projector's light sensor indicates the current
light intensity (vertical bar) and LiteLOC™ target (red horizontal line). The
LiteLOC™ target updates automatically by moving the bar up or down based on
the amount of light measured by the projector light sensor. The limits are self
adjusting, so the absolute scale is not important.
