Use the Light Settings dialog to edit lights, groups of lights, and global lights. You can either drag the slider or type a specific number. The options in the Light Settings window will change based on which lights are selected in the drawing view so that different fixtures can have different settings. To adjust multiple lights at once, add them to a group. To manipulate the settings of all lights in your drawing, use the global lights tab.

Lights settings dialog

The Light settings dialog is accessed from the quick properties box of a selected light, or from the 3D component tab.

The options in the Light Settings window will change based on which lights are selected in the drawing view. Each light will have some of the settings below.

Images in this article demonstrate properties using the Spotlight tool in the 3D Component Tab:

Basic

Brightness range and Brightness

Here, you can select a range of brightness of the light, in Lumens. There are four ranges to choose from:

• Weak light: 0 lm - 250 lm
• Light bulb: 250 lm - 1500 lm
• Ceiling light: 1500 lm - 6000 lm
• Floodlight: 6000 lm - 100 000 lm

Selecting a range automatically places the Brightness slider at a default position within the range, but you can click and pull the slider left or right to decrease or increase the brightness.

Spotlight

Light cone width

Adjusts how narrow or wide the focus of the spotlight is.

Light cone width: left = 40, right = 80

Position

Set the Elevation of your fluorescent lights only.

Size

Set the Fixture depth and Fixture width of your fluorescent lights only.

Color

Temperature

Controls the color of the light from 1500K to 7500K (Kelvins). Temperature can be adjusted for fluorescent lights, spotlights, and window light in the 3D component tab, as well as all lights from the Lights extension.

Temperature = 1500K	Temperature = 7500K

IES

Use IES

Selecting this checkbox lets you pick an IES profile from a set of predefined profiles. IES profiles control how the light is being spread. To change IES profile, click the black box and select one of the previews:

A cloud icon means that the profile is available in the cloud and that you can. Click the profile to download it. A hard disk icon means that the profile is available locally and can be immediately applied.

Diffusor style: Choose from None, Steel grid, or Plastic plate as a material to render beneath the lights in your fluorescent light fixture:

Quality: (window lights only)

Show in 3D photo: Check the box to display the fixture in the 3D rendering. If unchecked, the fixture will show in the 3D drawing view but not in a rendering. 

Show in 2D print: Check the box if you want the lights to be visible in your 2D printouts.
