About 8 years ago I replaced the lights in my Class C with LED's. That was generations ago in terms of LED technology but they were a huge improvement over the incendescent lights and sure drew a lot let juice. My current TT has all surface mounted LED's and we love them. I added extra LED's under the cabinets above the dinette benches to make it easier to read while lounging on the benches. I went with all bright white lights because it is easier for my old man eyes to read by.
I could not find anything like the puck lights like you used or I may have gone that route.
