Sunco BR30 floodlights should produce a beautiful 3000K color and be very quiet with a standard light switch. We installed two in our kitchen on a standard light switch and are happy with them. However these bulbs hum very loudly when connected to a Lutron CL Diva 150 Dimmer. In our case we have 6 of these bulbs on a dimmer of this make/model in our living room and they hum at all brightness levels except when the dimmer is on the highest Level set Low value. It's just annoying. After 3 weeks I just had to replace them. Instead I bought Maxxima LED BR30 75W dimmable 11W bulbs and the viola is peaceful and quiet. Now you need to understand that different models of LED lamps with different dimmers behave differently. So if you have a different dimmer your results may vary. But I'm giving this 3 stars because the bulbs have slightly discolored the white icing on the bulbs when off which only makes them look cheap when off. True, that only applies to 2 out of 8 bulbs in a pack. Of ALL the LED bulbs I've bought for our home, none of them have had this problem. So if you just hook them up to a regular light switch I don't think you'll have any problems at all. But if you have a dimmer or are a bit picky about how they look when they're off, you might want to think twice. Much luck.
