The VidaLite Modern LED Light works perfectly for what we purchase it for - accent lighting in our home movie theater. The black and brass color combo is reminiscent of old theaters, which is the look we are going for. The install wasn't difficult, even for a novice like me. While it is on a track, it isn't real track lighting because the lights don't shift along the bar. The light heads rotate a bit, which again, is great for us and how we are using them to highlight artwork. We have not tried this on a dimmer at all.
