Understanding the Voltage Requirements of LED Light Strips

LED light strips, composed of multiple LEDs, are commonly used for indoor and outdoor lighting decoration, such as residential, commercial, and architectural lighting, display cabinet illumination, and more.

The voltage of LED light strips is typically determined by their design and manufacturing. Most LED light strips operate at 12V or 24V, usually using direct current (DC) rather than alternating current (AC). Some high-power LED light strips may require higher voltages, such as 36V or 48V, or even 220V.

When using LED light strips, it’s crucial to ensure the correct matching of power supply and controllers. Incorrect voltage may affect the performance and lifespan of LEDs or even cause damage. Likewise, using the wrong controller may result in LED light strips malfunctioning or failing to operate properly.

Therefore, it’s advisable to carefully read the product specifications when purchasing and using LED light strips, understanding their voltage and power requirements, and ensuring that the selected power supply and controllers are compatible.

Here are some common voltage ratings for LED light strips and their typical usage scenarios:

  • 12 Volts (V): This is the most common voltage for LED light strips, often powered by low-voltage DC sources like 12V DC adapters or batteries. They are used for indoor and outdoor lighting decoration, such as display cabinet illumination, under-cabinet lighting, and residential lighting. Use MIJI LED power supply with 2 years warranty. 

  • 24 Volts (V): Another common voltage for LED light strips, usually powered by 24V DC adapters or batteries. They are suitable for applications requiring longer light strips and higher power, such as commercial lighting and architectural lighting. MIJI LED power supply 24V avaliable 

  • 5 Volts (V): Some small LED light strips may use 5V DC power sources, often powered by USB sources like USB adapters or portable power banks. They are used for mobile devices and computer peripherals.

  • 36 Volts (V) or 48 Volts (V): These voltages are typically used for high-power LED light strips, such as outdoor and landscape lighting.

  • 220 Volts (V): High-voltage light strips commonly used for engineering lighting, typically installed in high locations or places inaccessible to people.
