I just replaced all my old bulbs with new bayonet base led's, total of 16. I got them from Ebay, two packs of 10 for a little over $40 including shipping. They put out less light than the incandescents but no heat and it's adequate for us. I think the warm ones (mine) put out a little less light but are more pleasant. They're almost all from China anyway so it doesn't really matter. I could have stayed under $40 if I bought from China directly but I paid a few bucks more to get from a SoCal vendor. All I have left now are 2 flourescents in the ceiling but I don't use them much so prob won't replace.
