LED Strip Specifications
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
