Step-by-Step: How to Choose the Right Power Supply for Your LED Setup

Start with your control method — then choose the matching power supply.

1. Decide Your Control Type First
Pick the control or dimming method that fits your lighting application:
• Triac Dimmer – Standard wall switch dimmer (common in homes)
• 0-10V Dimmer – Commercial dimming systems
• ELV Dimmer – Reverse phase dimming (quiet, smoother dimming)
• RGB/RGBW Controller – For color-changing LED strips
• No Dimming – Basic on/off control
2. Choose the Right Power Supply to Match
Select a power supply compatible with your control type:
• Triac Dimmer → Triac Dimmable Power Supply
• 0-10V Dimmer → 0-10V Dimmable Power Supply
• ELV Dimmer → ELV Dimmable Power Supply
• RGB/RGBW Controller → Standard Non-Dimmable Power Supply
• No Dimming → Standard Non-Dimmable Power Supply
3. Match the Output Voltage
Make sure your power supply output matches your LED strip voltage:
• 12V LED strips → Use a 12V power supply
• 24V LED strips → Use a 24V power supply
4. Size the Wattage Properly
Choose a power supply rated for more wattage than your LEDs consume:
• Indoor Installations → Total LED wattage × 1.25 (125%)
• Outdoor Installations → Total LED wattage × 1.5–2.0 (150–200%)
This provides:
• Overload protection
• Cooler operation
• Longer lifespan
