I had a chandelier with 10 halogen bulbs. At full brightness I burned 400 watts of energy and warmed up the room. They give the same brightness with 10% power consumption. My only criticism is that the light is a bit harsh, but it works well with my Torchled 3000k recessed lights. Also, they don't seem to dim below 20% on my Zoos switches. So to evenly light the room, I typically need 40% on my other lights and 20% on these.
