Add programmable colour to patios, balconies, displays and outdoor-style decorations with this bulb strand fitted with NeoPixel RGB LEDs. Each strand has 20 cafe-style bulbs, and each bulb is individually addressable so you can create rainbows, chases, fades and other effects using a NeoPixel/WS2812 controller.
The strand runs from 12VDC rather than 5V, which helps over the longer wiring between bulbs. You will need a suitable 12V power supply as well as a NeoPixel/WS2812 controller, and the data input expects a 5V logic signal. If you are driving it from a 3.3V microcontroller without a built-in level shifter, use a suitable pixel level shifter.
Each bulb includes a small hook for hanging from a wire, fence or similar support. The strand has 'weatherproof' 3-pin DC connectors at both ends for extending runs, and it includes an input-side pigtail with brown, white and blue wires for power, data and ground. Adafruit also provides tutorial material covering NeoPixel wiring, power calculations and example code.

For longer runs, protect any exposed connector ends as recommended by the supplier, such as with hot glue or plastic wrap.
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- RGB
- Short for red, green and blue, the three primary colours of light that are mixed in varying amounts to make a wide range of colours. In electronics RGB can refer to an LED or pixel that blends these three colours, or to a colour signal or interface that carries separate red, green and blue channels.
