{"title":"Fixed Address NeoPixel LED Fairy Lights - 100 Wired LEDs","handle":"fixed-address-neopixel-led-fairy-lights-100-wired-leds","url":"/products/fixed-address-neopixel-led-fairy-lights-100-wired-leds","description":"These fairy lights use NeoPixel-compatible protocol and work with any NeoPixel library — but they behave differently from standard NeoPixels. Instead of acting as a daisy-chained shift register, each LED in this strand has a permanent pre-assigned address (0–100). When it receives data, it picks out its matching colour value and displays it. This means you can branch or parallel multiple strands and they'll all display the same data simultaneously.\n\nThe trade-off: you can't chain two strands end-to-end to extend the pixel count, and the addresses are fixed — you can't reassign them. But for parallel branch installations like hanging installations or tree lighting where you want multiple arms displaying the same pattern, these are ideal.\n\n\nImportant: Use a 5V DC power supply only. Do not exceed 6V — overvoltage will destroy the entire strand.\n\n\nKey Features\n\n\n100 LEDs – Pre-addressed 0 to 100, fixed permanently\n\nNeoPixel Compatible – Works with Arduino NeoPixel library, CircuitPython, and MakeCode\n\nFixed Address Design – Ideal for parallel/branching installations\n\nLED Spacing – Approximately 100mm (4\") per pixel\n\nWire Type – Solid-core magnet wire; flexible but shape-retaining; non-conductive coating\n\nLED Enclosure – Milky white epoxy blob; nearly indestructible\n\nPre-attached Connectors – Ready to connect; can also solder direct to wires\n\nNot Weatherproof – Keep dry; not suitable for outdoor wet environments\n\n\nWiring\n\n\nRed wire (coppery-red) – Power (5V)\n\nMiddle wire – Data\n\nRemaining wire – Ground\n\n\n\nTip: The wire uses a non-conductive magnet wire coating. Scratch or lightly burn the coating off before soldering. Avoid repeated flexing or abrasion at the connector cables.\n\n\nIdeal For\n\nBranching or tree-style LED installations\nParallel strands that display the same animation simultaneously\nCreative props, costumes, and decorative lighting\n\n\nResources\n\nNeoPixel Uberguide – Library, code examples, and wiring reference\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2817,"title":"Default Title","sku":"AF-4917","price":73.75,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
