I love these bulbs. After torturing myself with soul-sucking fluorescent lights for too long, I decided to warm up and order them. Last time I visited my local hardware store, one of the clerks told me that LED bulbs are replacing CF these days. I can't say I remember why, but thought of trying the LED bulbs next time I order. I have to say they are great. I have them in these hanging canisters and they are just the right size for mine. I like that they are not so dazzling when casually looking at them. Each bulb arrived in a beautiful box and without defects. Will place another order so all my canisters match.
