Single Colour Flex 12V/24V lights provide an array of vibrant and flexible lighting options for a variety of projects. Knowing the difference between 12V and 24V will ensure you maximise the benefits of your lighting, while avoiding issues such as burnouts or flickering. These flexible LED strips are suitable for larger and smaller areas, whether outdoors or indoors, provided you know the power differences.
What Is Single Colour Flex 12V/24V?
Single Colour Flex 12V/24V is a reference Flexible LED light strips that operate on either 12 Volts or 24 Volts of direct current power. They provide a single, consistent lighting that is consistent across the entire strip. They are extensively used in commercial, residential and special lighting designs in areas where consistency and reliability of colour are essential.

Some terms refer to related terms like 12V 24V LED Flexible Strip, Single Colour Flexible LED Strip 12V/24V and Single Colour Flex Rope Light 12V/24V. All of them refer to lighting products that are flexible and designed to run efficiently and safely at these voltage levels. Low Voltage Single Colour Flex is a different method of referring to the same type of product with a focus on energy-efficient and safe low-voltage operation.
Key Differences Between 12V and 24V Options
The voltage level determines the distance you are able to run the strip as well as brightness uniformity, power efficiency and the complexity of installation.
- 12V LED strips generally work best for small projects or shorter runs of less than 5 meters. They consume more power, making their performance less effective over long distances. They can also result in a voltage drop that leads to inconsistent lighting. It is typical to take them apart and reconnect them every 50cm.
- 24V LED strips can be used for longer or larger lighting projects, whether outdoors or indoors, up to 10 meters, without losing brightness. They require less electricity, but have similar power output. It means less wiring and a more constant light intensity across long distances. They also typically have wider cut points (around 1 meter).
If you connect the 12V strip directly 24V power in error, the LEDs will go out quickly. The powering of a 24V strip using 12V can cause flickering or dim light, but it doesn't damage it as quickly. The correct match of the power supply voltage and LED strip voltage is essential to ensure optimal performance and longevity.
Where To Use Single Colour Flex 12V/24V
The choice is based on the specific lighting requirements and the space available.
Indoor Small to Medium Spaces
A 12V single-colour Flex strip works well in the home as well as displays cabinets, under shelves and in accent lighting where the runs aren't very long. It's simple to install using common household power supplies that are low voltage. You'll get consistent, bright lighting for cosy or accent lighting.
Larger or Outdoor Installations

The choice of a 24V strip is the best option if you're looking to cover a larger area, like commercial areas, event lighting, or even outdoor features. The higher voltage can handle longer runs with no dimming and can be used from either end to ensure that brightness is evenly distributed. Additionally, the 24V model manages outdoor temperatures and humidity better if it is properly rated.
Speciality and Mobile Use
24V and 12V strips can be found in boats, vehicles and RV interiors, in which power sources are typically 12V systems. Flexible, neon rope lights provide elegant lighting for furniture edges, signs, and architectural details inside and outdoors.
Why Voltage Choice Matters
Voltage can affect safety, cost as well as the ease of use. Both 24V and 12V options are considered low voltage, which means they are safer and less electrical risk when in comparison to the mains voltage lighting.
- Safety Low Voltage strips aren't likely to shock you and are typically encased with silicone jackets that are resistant to shocks, water and wear.
- Energy Efficiency 24V strips typically draw less energy because they draw less current on longer runs. This can lower energy costs and also reduce the need for high-end wiring.
- Installation Comfort 12V wires are more widespread and are generally sold at a lower cost, making them ideal for smaller DIY projects. If you're planning larger spaces, wiring with 24V is more straightforward and provides power more frequently.
Experience gained from the Field
A lot of users are pleased with 12V strips because they are easy to cut and put in place for small projects. However, you will notice a different dimming pattern when you try larger areas. Moving to 24-volt strips fixes this issue because the power travels further with no loss.
One lighting professional said that they recommend 24V strips for commercial customers because of the soft, bright light that can cover larger areas better, particularly outdoors. However, homeowners love 12V for smaller shelves and decorative lighting since it works with their existing power sources and budgets.

Installation Tips for Single Colour Flex 12V/24V
- Always verify the voltage rating of your LED strip before connecting power.
- Use the appropriate power supply designed for either 12V or 24V.
- To run for longer lengths, think about the possibility of feeding power from both sides of the strip, particularly in 24V models.
- Cut strips at specific intervals to avoid damage.
- Secure strips using the appropriate glues or clips. Silicone-coated strips are durable outdoors and in humid areas.
- Don't exceed the recommended length of the run for each voltage to avoid flickering or dimming.
The best choice for you is to select the Single Colour Flex 12V/24V strip is dependent on your lighting requirements and space. 12V is a good choice for small, simple projects, while 24V is suited for larger installations that are more demanding.
