Lighting & Photometrics

The articles in this section provide helpful tips, tricks, and troubleshooting techniques specifically related to light fixtures and point-by-point photometrics.

📄️ Illuminance Levels Inside Building Outlines

When drawing building outlines for outdoor photometrics, make sure you use the Insert Photometric Solid Rectangle or Shape commands if you do not want illuminance levels to be measured inside the area.

📄️ COMcheck Lighting Export

You can use the Export to COMcheck command to export some lighting information in Design Master Electrical to a COMcheck file.

📄️ Incorrect Light Distribution from Light Fixtures

Odd light distributions can be caused by inconsistencies between the light fixture block and the IES file.

📄️ Light Fixture Cutoffs and Shields

Design Master Electrical does not have a way to configure light fixture cutoffs and shields, but you can approximate them using the Insert Solid commands.

📄️ Base Units and Photometrics Calculations

If your photometrics calculations appear too condensed or spread out, or the calculation takes a long time to complete, you may have your base units set incorrectly.

📄️ Light Fixture Tilt, Arm Length, & Elevation

The Tilt, Arm Length, and Elevation fields can be used to adjust how light distribution from IES files is displayed relative to the light fixture block.

📄️ Photometrics Calculations Taking Too Long

Several factors influence how long photometrics calculations take, from the area size to the number of fixtures and solids. This article explains each and suggests how you can reduce the calculation time.
