Description
Regulated WS2811 RGB Pixel String (12 V DC) – 12 mm Bullet, 10 cm Pitch, IP68
Addressable RGB Pixel String using the WS2811 protocol (Single-Wire NZR) for 12 V installations. The regulated electronics per pixel stabilise the light output across a wider input-voltage range and reduce visible brightness and colour deviation along longer runs.
What does “regulated” mean for WS2811 pixels?
With regulated, the supply relevant for LED/IC is stabilised inside the pixel. In practice, output remains more uniform over longer distances than with resistor-reduced (“resistor”) pixels. If voltage at the pixel becomes too low, a regulated pixel may shut down (typically below approx. 7–8 V at the pixel).
Core specs (base)
- IC / protocol: WS2811, Single-Wire NZR, up to 800 kHz
- Supply: 12 V DC
- Pixel: 12 mm bullet, RGB, individually addressable
- Pitch: 10 cm (4") standard
- Protection: IP68 (potted pixels)
- Wiring: 18 AWG / 0.75 mm²
Variants – how to choose
- Pixel count: e.g. 50 or 100
- Connector type: matched to your system (e.g. xConnect® or JST-SM – depending on portfolio)
- Cable colour: per variant
- Custom lengths: project-based/on request
Electrical planning (current, voltage drop, power injection)
- Planning current: up to approx. 60 mA per pixel at 100% white (RGB full)
- Example load: 50 px ≈ 3.0 A · 100 px ≈ 6.0 A
- PSU headroom: commonly +20–30%
- Power injection: depends on cable length, conductor size, topology and allowable ΔV
- Regulated: reduces visible effects of voltage drop, but does not replace proper injection planning
WS2811 data signal & system integration
- Signal: Single-Wire NZR; daisy-chain (pixel takes 24 bits and forwards the rest)
- GND reference: common ground between controller, injection and string is mandatory
- Controller → first pixel: keep short; buffering/signal conditioning is common for long leads
- Topology: structure large installs into power segments; route data according to controller design
Direct comparison: Resistor vs. Regulated
| Property | Resistor | Regulated |
|---|---|---|
| Principle | voltage reduction via resistors | stabilisation/regulation inside the pixel |
| Output under voltage drop | brightness/colour drift becomes visible | stable longer, then possible shutdown |
| Planning | earlier injection required | more tolerance, injection still required |
Outdoor & connector systems
Pixels are IP68 (potted). For long-term outdoor installations, the connector system is also relevant: xConnect® is typically designed for outdoor connections; other systems (e.g. JST-SM) may require additional sealing depending on installation (heat shrink, gel, enclosure, strain relief).
