ZERO STARS. There is no value here, these are junk lightbulbs made in China with no regard for quality. This is a pack of 9 bulbs and you will be using them all in ONE bulb in less than a year. I just replaced the bulb in my stairwell light with the 5th bulb. I installed the first bulb on March 1st, in fact the first bulb was done wrong so it didn't fit the fixture so it went straight to the bin. Technically, I installed the second bulb on March 1st. This light is difficult to get to and it takes a lot of effort to change the bulb, so having to change it every 3-4 weeks is annoying. For reference, the very first bulb I bought from Lowes lasted over 3 YEARS!
