Common LED Strip Powers

Basic Single Color 4.8W/m - 9.6W/m
High Density Single 14.4W/m - 19.2W/m
RGB Color Changing 7.2W/m - 14.4W/m
RGBW (White + Color) 14.4W/m - 24W/m

LED Driver Types

Constant Voltage (CV)
12V/24V output. Most common for LED strips.
Dimmable Drivers
0-10V, PWM, or TRIAC dimming capability.
Waterproof (IP67)
For outdoor or bathroom installations.

🔌 Wire Gauge Guidelines

Up to 2A (24W @ 12V)
1.5mm² wire for runs up to 10m
2A to 5A (60W @ 12V)
2.5mm² wire for runs up to 15m
5A to 10A (120W @ 12V)
4mm² wire for runs up to 20m
*Thicker wire reduces voltage drop over distance

⚠️ Safety & Installation

  • Always turn off power when connecting strips
  • Check polarity - LED strips are directional
  • Don't exceed maximum run lengths (usually 5m)
  • Use proper connectors - no twisted wire joints
  • Install drivers in accessible locations for maintenance
