Affixed lights to the top panel, soldered their connection to the control box, and attached the entire top panel to the rest of the frame assembly. Drilled and bolted a power strip to the side of the workbench to power all the CNC subsystems, including the panel lights and ventilation. Did a test and was quite impressed with the lighting. There are no shadows. I wrapped the LED strips in loops at the right angles to avoid soldering, which worked well.
