Have the chain bought here because of almost identical type that I know of the construction market, there is currently unavailable ("coming in spring again"). The chain here has the following disadvantages compared to the DIY-part: switch is not with rubber cap but simple slide switch: moisture enters the housing. Distance between the LEDs is half as long (10cm) but I did get situated for this application. A stripper is black instead of transparent. Metal clips to attach to a branch / floor / ... missing (mounting holes for but are there).

Addendum: The original battery, nursed back in the charger, one probably came in the evening for 10 minutes of light, it was rum again.
Battery I have now to still lying around batteries which are permanently self-discharge and therefore no good for other applications, replaced.
As the fairy lights hanging on the inside windows I take the plastic Lampenschirmchen pulled dried fruit pods of Physalis / Lampionblume on the LEDs. Now the light is warm / red / orange and not so cool white.
