•Lamp: Select Lamp from the Display Color menu to adjust the projector lamp
brightness.
• Mode: With the SC-50d/SC-60d, two lamp adjustment modes are available: Power
(recommended) or Intensity. The two modes are mutually exclusive; when you select
the Power mode, the Intensity selection in the Lamp menu is grayed out. Likewise,
when you select Intensity, the Power selection is grayed out.
• Power: To supply a constant wattage to the lamp, select Mode from the Lamp
menu and set it to Power. Then, select Power from the Lamp menu to set the lamp
power level. You can choose to run the lamp as bright as possible (this is the default
setting) or you can choose a lower setting. Generally, lower lamp output prolongs
the life of the lamp, but decreases brightness.
• Intensity: To maintain a constant brightness level, select Mode from the Lamp
menu and set it to Intensity. Then, select Intensity from the Lamp menu to specify
the desired brightness level. The projector automatically adjusts the amount of
power applied to the lamp as needed to maintain the desired brightness level.
• Color Temp: Select Color Temp from the Display Color menu to adjust the color
temperature. Color temperature establishes the “color of gray” by adjusting the 75%
white point to various color points.
What are “color points?” A “color point” is an x/y coordinate pair that defines a
color’s location on the standard CIE chromaticity graph, shown in Figure 4-7. (CIE
stands for “Commission Internationale de l’Éclairage” (International Commission on
Illumination), the organization responsible for color measurement and management
standards.)
1. The “Intensity” Lamp Mode setting cannot be used with the RVR
control (refer to RVR on page 68).
2. The Intensity value is not the actual lumen output, but rather a
correlated value only—1246 may represent 3500 lumens, for
example.
