When selecting an LED strip light there are many factors to consider, such as brightness, color, weatherproofing, and more. But what about voltage? The majority of strips are available in either 12V or 24V. So what’s the difference between these two options? Is one voltage better than another? What are the advantages of each?
The simple answer is that it comes down to your project. Each voltage is better suited for specific applications, and is only compatible with strips and accessories that are the same voltage. These factors can be easily used to guide your decisions.
24 VDC is less susceptible to voltage drop, meaning that it can illuminate a strip more consistently over a greater distance. If you need a longer line of light from one power source, 24 VDC is a great choice. While a higher voltage doesn’t inherently mean a brighter light, 24 VDC is also able to sustain higher densities of LED chips.
On the other hand, 12 VDC is a common voltage, so strip compatibility may eliminate the need for additional power supplies. If you are installing lights in a vehicle, for example, a 12 VDC strip light can often be directly connected to the existing electrical system. While there are certainly exceptions to this, and it is important to check your existing system before making a purchase, 12V strips can offer a more convenient installation solution in many cases.
All LED strips, whether 12V or 24V, offer exceptional efficiency and brightness within a low profile. If you still have questions, read below for more technical information. Learn the basic components that make strip lights work and how voltage may affect performance.
