Connecting LED Light Strips with Two Power Supplies
Introduction
Are you looking to connect multiple LED light strips to create an impressive lighting display? In this article, we’ll explore the best way to power your LED light strips for optimal performance. Whether you have a 20a 12v power supply on hand or you’re considering purchasing an additional one, we’ll discuss the pros and cons of each option.

The LED Light Strips
To begin, let’s take a look at the LED light strips themselves. You have a total of 6 strips, each measuring approximately 16.5ft in length. These strips are equipped with 150 LEDs, consuming 36w of power. They operate at 12v and draw 3a of current. Furthermore, you have the flexibility to connect up to 20 strips end-to-end.
Powering Strategies
When it comes to powering your LED light strips, you have two main options. Let’s analyze each strategy.
Option 1: Centered Power Supply
One approach is to use your existing 20a 12v power supply and position it at the midpoint, 50ft from either end of the light strips. By running the wires from the center of the setup towards each end, you can ensure sufficient power distribution. You mentioned having a 200ft spool of 12-gauge electrical copper wire, which will work perfectly for this purpose. This setup allows each strip to receive ample power, maximizing their lighting potential.

Option 2: Dual Power Supplies
Alternatively, you may choose to acquire an additional 20a 12v power supply, bringing the total to two. With this approach, you can position one power supply at each end of the LED light strips. The idea behind this strategy is to prevent any drop in current load. Think of it like a water hose; as the length increases, the pressure gradually decreases. By having a power supply at both ends, they effectively push power towards each other, ensuring that no current is lost. Each female power adapter from the LED light strips can then be connected to the corresponding male connector of the additional power supply using your 12-gauge wire.
AFQs
How do I connect LED light strips to two power supplies simultaneously?
To connect LED light strips to two power supplies simultaneously, you can use a parallel connection method. This involves splitting the LED strips into two groups and connecting each group to one of the power supplies.
What is the purpose of using two power supplies for LED light strips?
The purpose of using two power supplies for LED light strips is often to ensure an even distribution of power and prevent voltage drop, especially in longer installations. This can help maintain consistent brightness and color throughout the entire strip.

Can I use different types of power supplies when connecting LED light strips together?
While it’s generally recommended to use identical power supplies for LED light strips in the same setup, you can use different types if they have compatible voltage and current ratings. However, it’s crucial to ensure they are suitable for your specific LED strip requirements.
What is the difference between a parallel connection and a series connection for LED light strips with two power supplies?
The main difference between a parallel connection and a series connection with two power supplies is in how the LED strips are wired. In parallel, each strip connects separately to a power supply, while in series, one strip connects to the next, and both are powered by one power supply. Parallel connections are typically used when using two power supplies.
Is it necessary to use a splitter cable when connecting LED light strips to two power supplies?
When connecting LED light strips to two power supplies, it is not always necessary to use a splitter cable. A splitter cable can simplify the process by providing separate connections, but you can also achieve the same result by manually splitting the wiring.

How do I calculate the total voltage when connecting LED light strips with two power supplies?
To calculate the total voltage when connecting LED light strips with two power supplies in parallel, you simply add the voltage output of both power supplies together. For example, if each power supply outputs 12 volts, the total voltage would be 24 volts.
Conclusion
When connecting LED light strips, it’s essential to consider the power supply configuration. Whether you opt for a centered power supply or dual power supplies, you can create an impressive lighting display. Remember to use the appropriate wire gauge, such as your 12-gauge electrical copper wire, to ensure safe and efficient electrical connections. By carefully planning your power distribution, you can unleash the full potential of your LED light strips and enjoy a captivating lighting experience!
