Current (Amperes) x Voltage (Volts) = Lamp Power (Watts). 3) Adjust LiteLOC
before or after adjustment of lamp position.
There are two different lamp modes for general operation—you can maintain either a

Using LiteLOC
Maintain a specific brightness level from your lamp over time as follows (Figure

1. In the TPC's Advanced: Lamp menu,
adjust Lamp Power until the desired light
output is reached at the screen (typically
14 fL). Any LiteLOC
automatically be disabled.
2. Press "Set" to record the current
brightness reading in memory. NOTE:
Arbitrary units-of-measure are shown
above the light output bar.
3. Enable LiteLOC
