5VDC 5M WS2812B Addressable RGB LED Strip, IP65

These flexible RGB LED strips are an easy way to add complex lighting effects to a project. Each LED has an integrated driver that allows you to control the colour and brightness of each LED independently. The combined LED/driver IC on these strips is the extremely compact WS2812B (essentially an improved WS2811 LED driver integrated directly into a 5050 RGB LED), which enables higher LED densities. In the picture, you can actually see the integrated driver and the bonding wires connecting it to the green, red, and blue LEDs, which are on at their dimmest setting.

Current draw and voltage drop

Each RGB LED draws approximately 50 mA when it is set to full brightness and powered at 5 V. This means that for every 30 LEDs you turn on, your LED strip could be drawing as much as 1.5 A. Be sure to select a power source that can handle your strip’s current requirements.

There is some resistance in the power connections between the LEDs, which means that the power voltage near the end of the strip will be less than the voltage at the start of the LED strip. As the voltage drops, RGB LEDs tend to look redder and draw less current. This voltage drop is proportional to the current through the strip, so it increases when the LEDs are set to a higher brightness.
