They give INCREDIBLY bright white light so my advice is to know what you are buying (which I did not know at the time of my purchase). They are just too bright to be used in our kitchen or conservatory. The lighting is energy efficient, although not the most efficient I've seen. Once in the kitchen the dimmer controlled them with no problem and there was no electrical hum like I had with another set of bulbs that also claimed to dim the lights. Given the brightness, I've moved them to our porch lights where the difference between the old 60 watt halogen bulbs and these is striking - not quite bright and daylight, but bright versus dark. They are MUCH brighter than the bulbs they replaced and use about half the electricity. That's a big win.
