The WORST! Because it arrived BROKEN!I purchased a second buld from a different Amazon vendor -- It also arrived broken. Identical, totally inadequate Amazon packaging from both vendors. And then there is the time-consuming hassle of the returns.One would assume that with so much previous feedback about these bulbs arriving broken, multiple times to the same customer, that Amazon would have corrected the problem. Bad assumption on my part!Save yourself time and trouble - go buy the higher-priced bulb from your local hardware store. You'll pay more, but it will cost you a lot less.Do NOT buy until Amazon says they have addressed the problem.
