Why not go to home depot and get a few to try? A ham friend did just that to replace CFLs and had good results. More light from same watt rating with the LED bulbs. No RFI. Pretty cheap investment, easy to experiment with, just screw out the old and in with the new. No xformer required. No electrician required. -- de AB1VL NAQCC #6799 ab1vl.com
