power per unit of solid angle. The total luminous flux for a is the perceived
power emitted in all directions. Luminance is the total luminous flux incident
on a surface, per unit area.
Enter a photometric option to change [Intensity/Color/eXit] <I>:
Intensity Enter intensity (Cd) or enter an option [Flux/Illuminance]
<1500.0000>:
Enter an intensity value in candelas, the perceived power in a luminous flux
value, or illuminance value for the total luminous flux incident on a surface.
■ Candela (symbol: cd) is the SI unit of luminous intensity (perceived power
emitted by a light source in a particular direction). Cd/Sr
■ Lux (symbol: lx) is the SI unit of illuminance. Lm/m^2
■ Foot-candle (symbol: fc) is the American unit of illuminance. Lm/ft^2
Enter f to specify the perceived power in a luminous flux value.
Enter Flux (Lm) <18849.5556>:
If you enter i, you can specify the intensity of the light based on an illuminance
value.
Enter Illuminance ("Lx"|"Fc") or enter an option [Distance] <1500.0000>:
The illuminance value can be specified in either lux or foot-candles. Enter d
to specify a distance to use to calculate illuminance.
Enter Distance <1.0000>:
Color Enter color name or enter an option [?/Kelvin] <D65White>:
Specify the color of the light based on a color name or a Kelvin temperature.
Enter ? to display a list of color names.
Enter color name(s) to list <*>:
Enter a text string using wild card characters to display a partial listing of color
names, or an asterisk (*) to display all the possible choices.
If you enter k, you can specify the color of the light based on a Kelvin
temperature value.
Enter Kelvin temperature <3600.0000>:
Exit Exits the command option.
Shadow
Makes the light cast shadows.
Enter shadow settings [Off/Sharp/soFtmapped/softsAmpled] <Sharp>:
