Review on Outdoor Solar String Lights - 60ft 200 LEDs Fairy Lights, Solar and Battery Powered, IP67 Waterproof Rope Lights with RF Remote, 8 Modes, 3.6V/2000mA Solar Lights for Patio Decor (Warm White) by Tiffany Staley

These lights are much better than the previous cheaper lights we had. Line LEDs covered with an outer clear plastic tube (reminds me of speaker wire insulation), both ground pins and surface mount hardware are included, the front LED indicates when the unit is charging, which is the solar charger/control box separated from the string of lights so you can easily service/replace/troubleshoot your charger without having to pull the whole string of lights together. Cons: Neither the solar panel nor the mounts are adjustable (not a big deal really, the solar panels seem very efficient and charge even on cloudy days). ), CANNOT BE CUT. Okay, you can cut the strand to a shorter length, but that will put out the light. You will need to solder 2 of the 3 copper wires together (after the last LED of the new length) to make it work. The problem is that all 3 copper wires are the same color, coated or otherwise non-conductive so you can't test them with a jumper wire. My solution was to solder a short wire to all 3 copper conductors and then test the extensions. It works, but it hurts a little.
