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
Note: Pixels are IP68 (potted). Long-term outdoor suitability of the complete string also depends on the connector system/sealing.
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
Rule of thumb for calculation: ΔV = I · R (consider forward and return). Use multiple injection points for long feeds.
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

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).

FAQ
Does “regulated” replace power injection?
No. Regulated reduces visible effects of voltage drop, but power supply and injection points still must be designed correctly.
How do I size PSU and injection?
Approach: assume worst case (e.g. 60 mA/px), select PSU with 20–30% headroom, define allowable voltage drop, then derive injection points.
Is every variant outdoor-ready?
Pixels are IP68. Outdoor suitability of the complete string also depends on connector sealing and mechanical implementation.
