Review on 3M 9.84ft 3 Pin JST SM Male Female Plug LED Connector Cable for WS2812B WS2811 SK6812 Symphony LED Lights with Connectors, SM3P Buckle-Free Welding Plug Light Controller Wire (2-Pack) by Jun Merritt

These are 2pcs/pack. 3M 9.84ft 3 Pin JST SM Male Female Plug LED Connector Cable for WS2812B WS2811. worked as advertised. There is no noticeable "data loss" as other reviews claim. The LED strips worked the same as when connected directly to the controller. My setup is in/under the horsebox for "lighting". The Bluetooth LED controller has two outputs and is located in the weatherproof front pantry. Extension cords run between each controller output and each 16-foot LED strip—one extension per strip. The plug is small and goes through a hole about 1/4 inch. The LED strips run under the trailer attached to the frame rails.
