Of the 2 lamps was an obvious defect on the base. The lamp was not functioning warm white but clear cold white / blue almost white, absolutely unsuitable for human habitats in the long term. For the old lamp I got the money without hesitation back, for the complaint that it is not a warm white, there was no money for the 2nd lamp back, does so, only that I do not have rats stable where I use this lamp for lighting would.
