This is our old fiber optic fixture retro-fitted with a 1W LED in the cap.  It can be wired to our 24 channel LED and fits in our PVC Clip Track.  There is NO FIBER OPTIC cable anymore!  (If you want to add more fixtures into a pre-2012 LIGHTBOX System, we will provide it with a bushing insert to use with your existing 3mm black jacketed fiber)
