Actually, just the thing for balcony railings ......

Pretty lights, with proper fastening for balcony railings ......
would not the bitter aftertaste that already got a plastic tube broken. One of the 4 plastic tubes had already burst at the weld / glue line. During mating then blurted another, even at the weld / glue line :(
Had I not been looking forward to these lights, I would have returned again.
You can see the lights despite the bursting at the seam tubes use. Another possible mating everything and where it is broken, wrap it with black electrical tape somewhat, but for only 17, I expect flawless new.
LEDs function, otherwise everything well, just as mentioned, these vulnerable plastic tubes are prone to the weld / glue line.

I have a few days after the same lights in silver ordered Naeve Lights LED Solar Set of 4 / 1x white LED with 1x NiMH / AAA / 600mA / 1.2V including fastening belt / height 21 cm / diameter 5 cm / Material Plastic, silver 4076359
Everything was flawless.

Tip: This cool white light color is not really nice. I have (a 25ml 5 colors for 10 incl. E ***) bought bulbs paint and unceremoniously inked the LEDs according to my wishes. ;)
