Love these bulbs. They are very bright but dim enough to use on my chandelier. I have this tiered vintage chandelier from which I removed the ugly glass panels and added these bulbs to create the most unique steampunk lamp ever. I love that they are also dimmable as at least in my application they can be almost blinding so dimming is a must as they are exposed in my lamp. In my pack of 4 there were no defective bulbs. Very satisfied as they look great in my chandelier.
