These brackets are similar to the ones I created for my Prusa MK2S. They slide easily over the 2020 extrusion and hold tightly. They are designed to use the following LED light sourced from Lowes: https://www.lowes.com/pd/Utilitech-11-8-in-Plug-in-Under-Cabinet-LED-Light-Bar/1000033647

The light bar is motion activated (not by the printer) and is dimmable. For the Prusa brackets I angled the light at about 30 degrees but for the CR10 I angled it at about 15 degrees due to the additional height.
