Very satisfied with my purchase. Ideal for my aquarium aquatic turtles. I took my 2 for 2 lamps. Originally I had pliers to hang my lights. I was forced to slightly misalign them for normal use. The adhesive binding is very strong, impossible as it moves. Small clips for hanging the cable along the rod is ideal, this gives a very neat effect. It is possible to adjust the height of the stem more or less 10 cm + - 20-25 cm (including lamp) above the water.
