Operation

•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.

Note	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.

•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.)
