Make sure you know what bulbs you need when replacing them in your ceiling fan. I have found that not all ceiling fans use the same bulb/base. So I had to order an E12 base to replace some of my burned out 60w halogen bulbs. These 2700k tubes are the perfect replacement. The color signature (warm orange) is the same but shines brighter than halogen lights! I don't use them with a dimmer so I can't comment on how well they dim and flicker or not when installed. on the darkest setting. Since I haven't had any issues with this and the two I just used worked straight away, I'm assuming all the bulbs are working (i.e. not bad bulbs) and I'll be leaving this product 5 stars.
