Overhead Door conducted a test on some of the most common compact energy efficient light bulbs and determined which ones can be used in the Odyssey and Destiny openers.
After looking at the report below it looks like all the spiral style bulbs 20W and lower fit without a problem. The 23W Sylvania Micro-Mini and Earthmate Super-Mini fit the BEST! Utlitech and TCP 23W versions go in, but they do interfere with the lens cover. The lens will latch if pushed into position. The GE hybrid bulb that looks like an incandescent bulb does NOT fit!
Also note that many times installing an energy efficient light bulb in an automatic garage door opener can cause interference with the hand held remote. If your remote only works when you are close to your garage door after changing the bulb to a fluorescent light bulb then you might want to go back to the standard incandescent light bulb to resolve the problem.
