A strand of 20 digitally-controllable RGB LED pixel dots, each containing three 5050 RGB LEDs and a WS2801 controller chip. The pixels are encased in translucent white 30mm domes for weatherproof operation and even 180° colour spread, making them well-suited for outdoor signage and large-scale lighting installations.

Data is shifted from one pixel to the next via a clock and data line, so strands can be easily cut shorter or chained together. Each pixel is individually addressable with 24-bit colour (8-bit PWM per channel) and constant-current LED driving ensures even colour throughout the strand.

Key Features

• WS2801 Controller – 24-bit colour (16 million shades) per pixel
• 3× 5050 RGB LEDs Per Dot – ~4000 mcd total brightness per pixel
• Weatherproof Enclosure – Translucent white dome with mounting flanges
• Chainable – JST SM 3-pin connectors to link multiple strands
• Constant-Current Driven – Even colour output across the strand
• Two-Wire Control – Clock + data, works with any two digital pins on a microcontroller
