5V vs 12V LED Strips
5V vs 12V LED Strips — Which Should You Choose?
| Factor | 5V | 12V |
|---|---|---|
| Voltage drop | Significant — inject every 3m | Manageable — inject every 8-10m |
| Power draw | High current (e.g., 60A for 1024 LEDs) | Lower current (e.g., 20A for 1024 LEDs) |
| Cut intervals | Every 1 LED (usually) | Every 3-6 LEDs |
| Strip types | WS2812B, SK6812 | WS2815, GS8208, TM1814 |
| Compatibility | Most controllers (WLED, etc.) | Most controllers (WLED, etc.) |
| Best for | Small projects, matrices (tight spacing) | Long runs, rooflines, architectural |
