The lamp was delivered relatively quickly. Contrary to the description warmweiss this lamp by my count 4500-5000 Kelvin. So far from warm white. As for the dimming, so this is also not true. At full Bealstung you burn properly - but when dimming the lamp flashes. Is not so. From Stromspargruenden remains lamps in the lamp. But cozy dimmable light is different. Have more models ordered. If they are better, is replaced.
