HOW to Choose the Best Power Supply for LED Strip Lights
Select a power supply that matches the voltage and wattage of your LED strips. Calculate total wattage and add a 25% buffer for indoor use or 50% for outdoor use. Consider dimming compatibility, efficiency, and choose a waterproof design for outdoor projects. GL LED offers a wide range of power supplies and LED drivers to meet different project requirements:
1. By Voltage: Choose from 12V power supplies or 24V power supplies to match your LED strip voltage.
2. By Function: Options include 0-10V dimmable drivers, TRIAC dimmable drivers, and standard power supplies for non-dimming applications.
3. By Environment: Select waterproof power supplies for damp or outdoor use, or indoor drivers for dry environments.
With GL LED’s reliable and efficient solutions, you can find the perfect LED power supply or driver to ensure safe, long-lasting performance.
How to Calculate the Power Supply for LED Strip Lights
To select the right LED power supply, follow these steps:
1. Gather Information:
• LED strip length: Measure the total length of the strip light (in feet).
• Wattage per foot: Refer to the product specifications for power consumption.
• Voltage: Confirm the required voltage (e.g., 12V or 24V).
2. Calculate Total Wattage:
• Use the formula: Total Wattage = Wattage per foot × Length of LED strip light.
• Add a safety margin:
• For indoor use, add 25% to the total wattage.
• For outdoor use, add 50% to the total wattage.
3. Choose the Power Supply:
• Match the voltage (12V or 24V) to your LED strip.
• Select a power supply with a wattage rating equal to or greater than the calculated wattage (including the safety margin).
Example Calculation:
• LED Strip: 5 feet, 7 watts per foot, 24V input.
• Total Wattage: 7 watts × 5 feet = 35 watts.
• With Safety Margin: 35 watts × 1.25 = 43.75 watts.
• Recommended Power Supply: 24V, at least 44 watts or higher.
Key Tips:
• Always verify wattage and voltage from the LED strip’s specifications.
• Output for a power supply with higher wattage for reliability.
• For outdoor or damp environments, select a waterproof power supply.
This guide ensures you choose the right LED power supply to power your lights efficiently and safely.
