I bought 3 dozen of these lightbulbs to replace all the lightbulbs in all the bathrooms and have a spare lightbulb. One of them didn't fall out of the box. I contacted the seller via email and they quickly sent me two replacements for the dead one. The lightbulbs in the bathrooms are very bright. 3000K is a nice white light, although some describe it as 'soft'. I think it's "soft" compared to the 5000K. We had about 2700K, which was actually a bit yellowish.
