Check the enclosures. LED lights have controller boards that have to be cooled, lest they burn up. Some enclosures are just not compatible with LED bulbs or you may need a different style. You might consider halogen. They're still incandescent but far more energy efficient and, unlike CFLs, they don't require s hazmat suit to clean up when they break.
That said, CFLs are pretty awesome little feats of engineering too.
Check out the Technology Connections YouTube page. Dude has a few videos on lighting you might benefit from having watched.
