This is detailed photos of the 4-pin waterproof connectors located here: http://www.aliexpress.com/product-fm/313495011-100pcs-lot-waterproof-led-strip-cable-4pin-used-for-led-strip-RGB-color-wholesalers.html A "package" of them includes 100 males and 100 female connectors for a total of 100 connections (male+female.) The length is 180mm or 7.1 inches. The ends are completely encased in plstic and they ship with an o-ring end and a screw on connector to keep them from coming apart. The four wires at the end are tinned and are about .5mm in diameter (.019"). The outside cable sheath is 4.45mm/.175". I can't speak for the UV protection long term. Overall they seem nice.
