DC5V WS2812B Led Strip Light Individually Addressable WS2812 Smart RGB Led Pixel Strips Black/White PCB Waterproof IP30/65/67 Please Pay Attention: 1. The Price is Only Led Strip , Not Included Power Supply and Led Controller. 2. WS2812B Must Use DC5V Power Supply and Pixels Led Controller to Control. 3. Every 0.5 Meter with Solder Joints , It Is Very Normal In an Electronic Product, It's Not a Quality Problem. 4. WS2812B Led strip Can Be Cut Between Each Led To Create Custom Lengths, Please Do Not Bend LED Strip Sharply. 5. The 3 Pin JST Connector of LED Strip Included: Red: VCC, Withe: GND, Green: DATA. 6. The LED Strip Has 3M Adhesive Tape On The Back of PCB ( Except Ip67 ). Please Make Sure Installation Surface Must Be Smooth, Clean And Dry. 7. Longer LED Strip Runs, Please Power From 2 pin Power Wire of Both Ends To Reduce Voltage Drop. How to Choose LED Power Supply and Pixels Controller? First, Calculated The Whole Led Strip Lights Watts. One Led Chip is About 0.3W, If You Buy 5m 60Leds/m ( Total LED Strip is 300 Leds ), So 0.3W*300=90W. Then, Choose the Right Led Power Supply. This Led Strip is Work with DC5V Power, So 90W / 5V=18A ( At Least 18A or more ). Finally, Choose the Right Pixels Controller You Like. WS2812B Led Strip is Controlled By Single Data Line Controller. So you could choose them from our store, we have IR/RF Remote, Bluetooth, Wifi, Music APP and Computer controller etc. ( If you can't recognize them, you could feel free to contact us, we will glad to help you ) Note: White PCB / Black PCB. 30leds/m, 60leds/m, 144leds/m.
