These bulbs were used in a 12 bulb chandelier, previously used incandescent bulbs. These bulbs work very well. Although I didn't bring a light meter, I'm sure they give more light. I already installed an LED compatible dimmer so no further steps were required. They dim nicely at a very low level. The shape of the chandelier is such that it extracts heat from the bulbs, and with the old bulb it went quiet. Also, the heat seemed to attract and hold dirt. With these lamps we get more light, much less heat and a chandelier that requires less cleaning. It's worth noting that the energy savings more than offset their higher price tag than incandescent bulbs, to the point where even if they haven't burned out, it's worth replacing.
