We had under the wall cabinet for years lamps with cabling. When they went broke, I was looking for a wireless alternative and found it here. I wonder a little that others can read it, the brightness is low in my eyes. From hanging cupboard there are up to the sink at us almost 40 cm and I see light with little more than without. Even with three lights next to each other is the luminosity with us is not sufficient to see when flushing slightly.
On the positive side, in my view, that they keep well and can be easily switched on and off. Because they do not make neat light, they were totally unsuitable for our purposes.
