Who does not want in the whole house to replace the old lamps with modern LED concepts and still has lights that are tailored to the 'old' light bulb, this lamp itself should see once. With regard to appearance and color of light it is a wonderful retro-fit. Pleasantly warm, yellowish light and all-round illumination.
Small downside - because the lamp is not dimmable, you have to choose the wattage already fit for purpose, a later correction of the brightness is not possible. The 4W indicated are MMN. enough for a desk lamp; on the ceiling, it would have to be a little more for my taste.
