I bought these about a year ago when we moved into our house. I have a light fixture throughout the house that uses these bulbs and it uses three bulbs. I have bulbs with pigtails in two cartridges and this bulb is in the last one. And in one year I went through 8 lightbulbs. They last about a month. If it hadn't taken me so long to pull out the ladder and change the lightbulb, I probably would have searched the whole box by now. Don't waste your money.
