Load your lightbeam brushes

To install the Lightbeam Brushes in Photoshop CC, copy the DCM Lightbeam Brushes.abr file from the download to your computer by dragging and dropping it.

Now open Photoshop CC, and go to Window > Brushes.

In the Brushes Panel, click the flyout (the four-bar icon in the top-right of the panel), and choose Import Brushes from the dropdown list. Navigate to the folder into which you had copied the DCM Lightbeam Brushes file, and double-click on it. Your new brushes will be recognised by Photoshop, which will install them automatically. Scroll down to the bottom of the list in your Brushes Panel to find them. Each brush has a small preview to help you tell them apart.
