I can only say that the luminous means exactly what I expected. Qualitatively very well made and used in a bathroom lamp and perfect light. Even just in this field of application (4 x in the lamp) It is also bright enough. Extremely helpful here, the exact details of the dimensions. Super. The lamp is also warm white, where you have to make reductions compared to traditional light bulbs as with almost all LED lamps. But as part of the LED lights fits here definitely an indication. The shipping and contact, incidentally, was also very quick and easy.
