Great fixtures! You have me puzzling about getting the insulators to glow. I appreciate that you don’t have the time to experiment. Ideas: (1) try to create an edge lit effect and place diffused LEDs around the ring on the end of the insulator. (2) use more smaller LEDs and point in different directions, spray frost the inside of the insulator or (3) embed the LEDs in a translucent epoxy. These are things I’ve tried for cosplay lit buttons, and backlit acrylic engraved signs. The only thing that matters is they look great and are a great accent on the space.
