Addressable WS2811 IC Strip:DC24V 3m 864LEDs/m 26W/M White PCB WS2811 COB LED strip light, FPCB Width: 12mm , one WS2811 IC can control up to 36 lamps. Higher light output, Ra>90, 180°beam angle design. WS2811 RGB with an addressable controller can display thousands of dynamic colour effects such as rainbow, chasing. Please note: The colour sequence of the light bar is BRG (not RGB). IP66 Waterproof FCOB LED Strip: Different from common IP65 strip, our IP66 strip is covered by the heat shrink sleeve on the outer layer, which can protect the COB strip from splashing water and from heat greatly. Ideal strip for installation in bathroom or other areas with slight moisture. Compared with 5050SMD LED strip, FCOB strip produce more uniform and brighter linear lighting effect due to no dark spot. (Voltage drop should be taken into account when using) Control Methods: It can be controlled by RF remote, App and Alexa/Google Home Voice control. Recommended Controllers: This LED light must work with SPI RGB controller. It is compatible with addressable controllers such as SP530E(B0CSCLP31T), SP630E(B0BTYJQDNB), SP611E(B09GVK267L) etc. and can be used with Arduino, Raspberry Pi, K-1000C and other programming controllers. (Controller need to be purchased separately) Great flexibility: Double-layer FPCB compensates for voltage drop, heat dissipation and flexibility. Flexible PCB board, 3-pin JST-SM connector on both ends for easy installation and connection of LED strips in series. The soldered part can be cut off, but we do not recommend cutting the IP66 waterproof strip in case it may affect the waterproof performance. Wide Application: Colorful and dreamy light suitable for bedroom, kitchen, living room, club, bar, party, Christmas, wedding and so on. The high quality strip makes each LED light glow evenly and has a lifespan of over 25,000 hours, helping you save money and time on repairing. Packing list: 1x3M IP66 Waterproof FCOB WS2811 IC RGB LED strip(Controller and power supply NOT included).
