Features: [FCOB RGB IC LED Strip] 720LEDs/m 21W/m 12mm WS2811 RGB COB LED strip, one WS2811 IC can control 36 beads. 3PIN. IP30 non waterproof. DC24V. COB LED strip with multiple chips on the board can provide brighter and more uniform light than SMD LED strip. Ra>90, no black spots. Please note: The color order of the strips is BRG (not RGB). (Note: Controller and power supply are not included). [Dream Color Effect] Our FCOB RGB LED strips have a built-in WS2811 IC, which allows multiple colors to be displayed on the LED strip at the same time, with segmented control. When connected to a compatible SPI controller, the WS2811 RGB FCOB strip can display thousands of dynamic color effects such as rainbow and multi-color chase effects, which are not possible with ordinary RGB LED strips. 【Cuttable and Linkable】Flexible LED strip.The interval between the two Cut Mark measures 1.96in(50mm). 3PIN connector on two ends ,one is female the other one is male .It also support end to end connect in series .12mm width . 【Safe Low Voltage】Compared to regular LED strip lights,the light is soft and uniform,which is safer to your eyes. With real double-layer FPCB board,the FCOB LED Strip Light has better heat dissipation than others,it's safe for children and pets. 【Easy Install】Widely Application.Suitable for interior decoration. Such as kitchen, cabinet, bedroom, stair, mirror, corridor, DIY backlight, table lamp, toy light, DIY lighting, special use and other lighting.Come with double-side tape and fixed clips (IP30 Indoor Use Only). 【Packing list】Power supply or controller is not included .1XLED Strip, 1X3PIN Male Connector Specification: LED Type: FCOB SPI RGB IC Flexible Chip On Board LED Strip Input Voltage: DC24V LED Quantity: 720LED/m, 20IC/m, Group of 36LED addressable LED Strip Width: 12mm Waterproof level: IP30 Non-waterproof IC type: WS2811 IC Operation temperature: -4℉~113℉(-20℃~+45℃ ) Storage temperature: -4℉~104℉(-20℃~+40℃ ) Ways of working: Work with a controller- RF remote ,Bluetooth ,WiFi, Alexa Wave length(nm): Red:620nm ; Green:525nm ; Blue:460nm Total length: 16.4FT (5m) NOTES: Group of 36LED addressable. 1 pixel=1 IC chip=36 LED FPCB board color: White Recommend power supply: DC24V3A (Power supply or controller is not included)
