Work wonderfully. For about 6 months 8 as corridor lighting in use. Instead of 35 watts per piece only 3.2 are consumed. Light is a little colder than the old halogen lamps. And also a little lower luminosity. But is hardly noticeable. Our hall has eh walls and furniture with warm colors. Had a rather sterile white hallway which see might be different. But who is set up at home like at the dentist, which is certainly not interfere. Cold stays cold. So we do not even have 10% of the former electricity costs. And there in the hallway the light is often, the acquisition will be amortized quickly. Top.
