After two nights of continuous operation, I am very satisfied. Two of these LEDs went into a new living room ceiling lamp. Very pleasant the room now with only 26W consumption neat light to get. The light color I feel also as pleasant, similar to a light bulb. As with all our LEDs, the brightness is also here at power since immediately. Carefully you have to be just because of the size: these LEDs are much larger than conventional bulbs, so that I had serious doubts whether the purely fit. Went with my light then however, but the 7cm diameter could even cause problems.
