Light Fixture Project Schedule

The light fixture project schedule contains the light fixtures used in the current project. To create and modify light fixture types, go to

Rename: Press this button to rename the displayed light fixture in the schedule. Any labels on the drawing will be updated.

Find: Press this button to select a light fixture from a list of all of the light fixtures in the schedule. The light fixture you select will be displayed in the dialog box, allowing you to view and modify it.

Next: Press this button to select and display the next light fixture in the schedule. The next light fixture is determined by sorting the entries in the schedule alphabetically. If you press this button when viewing the last light fixture, it will wrap back to the beginning and display the first light fixture.

Previous: Press this button to select and display the previous light fixture in the schedule. The previous light fixture is determined by sorting the entries in the schedule alphabetically. If you press this button when viewing the first light fixture, it will wrap to the end and display the last light fixture.

Copy: Press this button to copy the displayed light fixture in the schedule. The new light fixture will be created with the same information as the displayed light fixture.

Save: Press this button to save any changes made to the displayed light fixture in the schedule. If you make changes and do not press this button, you will be prompted to save your changes before selecting a new light fixture or closing the schedule dialog box.

Delete: Press this button to delete the displayed light fixture type from the schedule. If there are any light fixtures inserted on a drawing in the project that use the light fixture type, you will not be able to delete it. You must first delete all of the light fixtures from the drawings before you can delete the light fixture type.

The information in the Photometric Calculation Information section is used during the illuminance level calculations. All of this information must be provided and be correct for the calculation to be correct.

•	One: Light is distributed once in the direction of the insertion angle of the light fixture.

•	Two, 90 degree offset: Light is distributed in the direction of the insertion angle of the light fixture and at 90 degrees counterclockwise.

•	Two, 180 degree offset: Light is distributed in the direction of the insertion angle of the light fixture and at 180 degrees.

•	Three: Light is distributed in the direction of the insertion angle of the light fixture, at 90 degrees clockwise, and at 90 degrees counterclockwise.

•	Four: Light is distributed in the direction of the insertion angle of the light fixture, at 90 degrees clockwise, at 180 degrees, and at 90 degrees counterclockwise.

Lamp Depreciation: The depreciation value of each lamp (Lumens / lamp x lamp depreciation = actual lumens). It should be less than or equal to 1. Lamp depreciation may include fixture dirt or lens depreciation.

Arm Length: The length of the arm of the fixture. When calculating illuminance levels, the light source is moved this distance from the insertion point of the light fixture block.

Default Mounting Height: The default mounting height when this light fixture type is inserted on the drawing. The mounting height can be modified for individual light fixtures during and after insertion.

IES File: The IES file that is associated with the light fixture callout. IES files are provided by light fixture manufacturers and contain photometric information about the fixture. They are necessary in order to calculate the foot candle levels in your project.

IES Rotation: The counterclockwise rotation of the IES file relative to the fixture in degrees. Use this value to rotate the IES file if it does not point in the same direction as your light fixture block.

Scale Factor: Multiplies the light output by the number specified. For use with IES files for LED light fixtures.

Select IES File: Press this button to select the IES file for the light fixture. The Select IES File dialog box will appear.

Select the IES file for this light fixture and press the Open button. The IES file will be attached to this light fixture and you will be asked if the information is to be added to the project schedule.

Press the Yes button to add the information to the project schedule. The information contained in the IES file varies depending upon what the manufacturer provides. You will need to review the information that is loaded to confirm it is loaded into the correct field and that it contains useful text.

Press the No button to only add the information from the IES file used for lighting calculations. The other information in the light fixture schedule will not be filled in based upon the information in the IES file.

Once an IES file is attached to a light fixture, the file path is displayed in the IES File field of the dialog box.

Load IES File Information: Press this button to load the IES file information into the project schedule. The information contained in the IES file varies depending upon what the manufacturer provides. You will need to review the information that is loaded to confirm it is loaded into the correct field and that it contains useful text.

All of the information from the IES file will be loaded into the project schedule.

Detach IES File: Press this button to detach the IES file from the light fixture. The light fixture will have no IES file associated with it after pressing this button.

The block used to represent the light fixture on the drawing is shown here. The list of blocks can be modified using the Light Fixture Blocks->Edit Project List command.

Select Block: This button opens the Select Light Fixture Block dialog box. This dialog box allows you to choose the block used to represent the light fixture on the drawing.

The information in the Schedule Information section is displayed in the light fixture project schedule on the drawing. It is informational only and not used in the calculations. You can provide it to include a more complete description of the light fixture in the schedule, but it is not necessary. All of the fields in this section can be left blank and the calculations will be correct.

Include in Schedule: Whether the light fixture type is displayed in the light fixture schedule that is inserted on the drawing. Most light fixture types will have this box checked. It is most commonly unchecked for existing light fixture types.

Fixture Description: A description of the type of light fixture. This description will appear on the light fixture schedule on the drawing.

Model 1, Model 2, Model 3: A description of the model for the light fixture. In the light fixture schedule, the three models can be shown in a single column or in three separate columns. See the Edit Light Fixture Schedule List section for more information.

Note 1, Note 2, Note 3: These notes can be used as generic note fields that are displayed in the schedule on the drawing.

They can also be used to include information for which the software does not include a specific location. In the column labels, you can change the label on the column for that note to designate it for that information. When the schedule is printed, you will have a new field that includes the custom information.

Ballast: The type of ballast on the light fixture. Default ballasts are available in the list. To specify a ballast that is not included in the list, select Custom and enter the value in the field below.

Mounting: How the light fixtures is mounted. Default mounting types are available in the list. To specify a mounting that is not included in the list, select Custom and enter the value in the field below.
