This should be a good start. I use them in ALL my fixtures now. They are a little more expensive and do not throw as much light,however I can live with it. Even the swirls. If you have them you know what I mean. I like the idea of if I leave a light on overnight they also stay cooler than the regular bulbs. I have no spotlights on the exterior, I suppose this may create an issue for some. Exterior is solar lighting, we actually have a few which are really bright for being solar.
