So, I happened upon these while looking for other bulbs and thought they would look great in a longer chandelier and I was right. They make all the crystals shine beautifully and are a fan of brighter white light, perfect. It says 4000k and I have burned myself on them in the past but they are not yellow at all and fade very nicely. Excellent bulbs with a tiny defect, one bulb out of six on one side only, so half burned out. Maybe a bug, but that's the only downside in my opinion.
