Decided I have for these lamps, because they are significantly cheaper than other LED lamps plant. After 2 weeks they have already been delivered, although they are indeed from China. Have the same 4 pieces ordered, because I wanted to use each 2 for my Medinilla and on the length of operation so can not say anything yet. All 4 function properly. Have 2 of them since about 6 weeks of continuous use. In my plant, they get very well, has even started to set new leaves. Higher power consumption is not noticeable in my total consumption. Can these lamps therefore only recommended because that value for money is great and I do not think there are differences to the more expensive LED bulbs. I for one will buy again these lamps, if I have to replace my sometime.
