The most reliable connection technology in outdoor lighting. The solder shrink connectors contract under heat and the integrated solder begins to melt. After completing the heating process, we have a 100% secure industrial cable solder connection which is already waterproof. So that the water cannot be transported further between the space between the cable sheath and the inner conductor, a shrink tube with adhesive is pulled over it and shrunk. Thus we have a 2-fold security against ingress of water. 
 
The set includes:
30 pcs. Solder shrink connectors (3 per connection from one lamp to the next, 2 for the last lamp) 
10 pcs. 12cm heat shrink tubing pieces 18/6 with glue
