Controlling The Brightness Of A Light Source - Autodesk 24000-000000-9860 - Revit Architecture - PC User Manual

Controlling the Brightness of a Light Source

In a project, you can change the brightness of a light source using the following methods:
Change the Initial Intensity. For example, if you want to change the bulb in a table lamp from a 60 watt
bulb to a 100 watt bulb, change its Initial Intensity value in the type properties.
Change the Light Loss Factor. To enhance or reduce light output to reflect environmental factors in the
project, change this value in the type properties for the lighting fixture.
Dim the light. Use this method, for example, if you want to represent a ceiling light that is dimmed to
create mood lighting in a rendered image.
