I am very pleased with this LED bulb. Already several LED bulbs from different vendors tried and this has been the best by far. The perceived brightness I would even compare with a conventional 100Watt bulb. Comes possibly from the fact that the light is focused downward as with reflector bulbs. Especially in rooms that do not have natural light (eg hall) is the class. Especially since our lamps are directly under the Ceiling with orientation gen floor illuminate everything perfectly.
