2 pcs/pack 3M 9.84ft 3 Pin JST SM Male Female Plug LED Connector Cable For WS2812B WS2811 SK6812 Symphony LED lights with connectors，SM 3 pin without soldering light controller wire

Good quality extensions connectors fit perfectly and I've had zero issues with them and if I ever need more in the future I'll be sure to get these again.

I recently recieved one of those diesel heaters and wanted to extend the controller about 8 feet from where the heater assembly will be located. I was ready to build an extension when these turned up. They are a "Plug and Play" harness. All I need to do is unplug the control assenbly and plug it into this harness and I am up and running.Included in the resealable zip lock bag were two 9.8 foot harnesses and two pig tails for use if needed. I did not need them. Such a reasonable price and I still have parts left for another project when the time comes around.

My only issue is trying to get the kinks out of the cable from the way its wrapped and packaged. Other than that the cables work great

This 2 pcs/pack 3M 9.84ft 3 Pin JST SM Male Female Plug LED Connector Cable For WS2812B WS2811... worked as advertised. No noticeable 'data loss' as claimed by other reviews. Strip LED lights worked the same as when connected directly to the controller.My installation is in/under a horse trailer for 'underglow'. Bluetooth LED controller has two outputs and is located in the front tack room protected from elements. Extension cables run between each controller output and each 16 foot LED strip - one extension per strip. The connector is small and fits through about a 1/4" hole. The LED strips are run under the trailer secured to the frame members.

Perfect match to extend my existing cable to the length needed. The original install could not be completed because the cable provided was not long enough and extensions were not offered. This pair of cables completed the connection with ease and no splices necessary. Install maintains a professional appearance.

These are a simple way to extend the wires connecting light strings to your controller.

I've used these things on raspberry Pi's, bread boards and other DIY projects where I needed a switch.

I have a 2 LED strip setup with 2 WS2811 LED strips, a SP110E LED controller that has parallel output for the 2 strips, and a 12 volt 5 Amp power supply. The game plan was to use the 2 extender cords to go from the 2 strips to a weatherproof box for an outside installation. When I put both of the extension cords on the outputs of the LED controller I was getting color flashing, incorrect colors and noise in the data. I tried only one cord connected to the LED controller with the other output directly to the 2nd strip and it works ok even at the highest brightness with a mainly white pattern, so 1/2 the problem solved. The LED strips are the standard 5 meter (16.4 feet) strips by the way. Maybe 2 shorter extensions will work... These together don't....
