Resistor or Regulated?
The right 12V WS2811 LED pixel solution for your project
Find suitable 12V pixelsVoltage Reduction: Two Methods Compared
Option 1: Resistors ("resistor")
This simple method uses built-in resistors to reduce voltage. Advantage: low price. Disadvantage: longer chains cause voltage drop – pixels appear dimmer or color-shifted.
Option 2: Voltage Regulators ("regulated")
A linear voltage regulator ensures a constant 5V – even from e.g. 9V input. Brightness and color remain stable. If voltage drops below approx. 7–8V, pixels stop working.
Direct Comparison
| Property | Resistor | Regulated |
|---|---|---|
| Technology | Resistor voltage drop | 5V via regulator |
| Brightness | Decreases with length | Stable |
| Max length | ~5–6 m | ~10–12 m |
| Price | Cheaper | More expensive |
| Fault tolerance | Robust | More sensitive |
