Hi Kurt, I found the Bayonet magnum ring (1c and 2c) on the Dr.led web site. I couldn't see any difference between the 1c and 2c version. Can't locate the Planet m. Which site is that one on? Do these led's fit inside the standard Catalina salon light fixtures with the lens in place?Gene Musante 617-755-0680 gmusante at msn.com
