LED strip length refers to the measurement of flexible, tape or rope-like light fixtures that come in reels. These reels usually measure five meters, considered the standard size for LED strips. The 5m LED strip is widely available and can be easily cut to size due to designated cut points.
Apart from standard sizes, LED strips come in various lengths, and you can customize them to suit your needs. However, as the strip length increases, the voltage must also be increased to maintain consistent brightness throughout.
Voltage plays a crucial role in determining the length of an LED strip. As the strip length increases, so does the resistance to electricity flow, causing a voltage drop.
The LED strip’s voltage must be increased to ensure proper current flow and consistent brightness. When selecting an LED strip for your project, remember this relationship.
A higher voltage rating is better for a strip of the same length. For example, a 5m strip with 24V outperforms a 5m strip with 12V.
Understanding voltage drop is also essential when considering LED strip length. Voltage drop occurs when the voltage decreases along the strip due to resistive materials, causing the strip’s end to be less bright than the beginning. Choosing the right voltage for your LED strip ensures minimal voltage drop and consistent brightness throughout.
LED strips come in different lengths, from a standard 5 meters per reel to longer lengths of up to 60 meters. The length of an LED strip depends on the voltage rating and project requirements. To give you a better idea, here’s a table highlighting different LED strip lengths and their corresponding voltage ratings:
LED Strip Length | Voltage Rating |
5m (standard) | 12V or 24V |
10~30m | 24V or 36V |
30~50m | 24V/36V/48VDC/110V/220V |
60m (longest) | 48V constant current/110V/220V |
>60m | Under developing |
As you can see, longer LED strip lengths require higher voltage ratings to maintain consistent brightness throughout the entire length. It’s important to select the appropriate voltage rating based on the length of the LED strip to ensure optimal performance.
The length of an LED strip can significantly impact its performance, with the constant voltage rating being a determining factor in strip length.
The market’s most common LED strip length is 5 meters, typically available in two constant voltage options: 12V and 24V. The 5-meter, the 12-volt LED strip has cut marks every three LEDs and is often used for indoor lighting in areas such as bedrooms, living rooms, and offices.
In contrast, a 5-meter LED strip with a constant voltage of 24V provides similar brightness to a 12-volt strip. However, the cut marks are spaced differently, with a mark after every six LEDs.
When choosing an LED strip, it’s essential to consider the constant voltage rating, as it impacts the strip’s performance and compatibility with the power source. The table below presents some typical lengths of LED strips and their corresponding constant voltage values:
You may be wondering whether a 12VDC or 24VDC LED strip is the better choice. Let’s compare both options to help you decide.
For a 5-meter LED strip, both 12V and 24V options have the same light output, but the amperage and voltage combination varies. For example, a 24W/m LED strip will draw 2.0A/m for 12V and 1.0A/m for 24V. However, this difference in amperage does not affect light output. The 24V variant is more efficient, drawing less amperage and performing better with the LED strip and power supply.
If you need to increase the length of the LED strip, the 24V option is better. By connecting two 5-meter LED strips, you can extend the length to 10 meters. A 12V LED strip will experience more voltage drop and reduced performance when connected to a longer strip, while the 24V variant can handle twice the load of the 12V strip.
In terms of flexibility in sizing, the 5-meter@12V option is preferable. However, if you have a larger installation or want to avoid voltage drop issues, the 5-meter@24V option is the way to go.
The key differences between the two options are:
Parameters | 12VDC | 24VDC |
Amperage | High (2.0A/m) | Low (1.0A/m) |
Efficiency | Less efficient | More efficient |
Voltage drop | More significant | Less significant |
Sizing flexibility | High | Low |
Suitable for a larger installation | No | Yes |
Constant Current LED strips are an innovative option for those who need long-lasting lighting without voltage drops. These LED strips provide a constant current, ensuring consistent brightness along the entire length of the strip. Constant current ICs on the PCB or ICs inside the LED maintain the current, preventing brightness loss due to voltage drops.
These LED strips are available in lengths ranging from 50 meters to 30 meters and from 20 meters to 15 meters per reel. They have thicker PCBs that range from 3 to 4 ounces in weight, making them more durable and long-lasting. They are also available in a variety of colors, including single color, warm white, adjustable white, RGB, RGBW, and RGBCCT.
Constant Current LED strips are highly waterproof, with an IP65/IP67 rating provided by the silicone-integrated extrusion process, making them ideal for outdoor use. They also have a high color rendering index (CRI>90) and 3-step MacAdam, resulting in more vivid and accurate color representation.
Constant current LED strips come in various lengths, and choosing the right length is crucial for ensuring uniform brightness. Here are some popular lengths available for constant current LED strips:
This LED strip is suitable for large spaces that require extensive lighting. The 48VDC rating ensures that the brightness remains consistent from the beginning to the end of the strip.
The 30-meter constant current LED strip requires 36VDC to provide uniform brightness throughout its length. This strip is perfect for mid-sized indoor spaces.
If you need a smaller constant current LED strip, the 20-meter option with a 24VDC rating can provide uniform brightness without voltage drop issues. Although you can use 5-meter @ 24VDC constant voltage strips and connect them to create a 20-meter strip, this can lead to voltage drop issues, and adding extra wiring for each strip can make the circuit more complex.
AC driverless LED strips are high-voltage LED strips that don’t require a driver to operate. Alternating currents power these strips, and the PCB has a diode rectifier. This means they don’t need a power plug, making them a convenient and easy-to-install choice for various applications.
AC driverless LED strips have a much shorter cut unit length of only 10 cm compared to standard high-voltage LED strips. This makes them ideal for applications where precise length adjustments are needed. They can also run up to 50 meters with just one plug-in, which means fewer power sources are required.
AC driverless LED strips come with additional features like high-quality PVC housing for extra safety, injection-molded end caps, and end caps that don’t require solder or glue. They also have built-in piezo resistors and safety fuses to protect against lightning, making them a safer and more reliable choice for both indoor and outdoor use.
Length is an important factor to consider when it comes to LED strips. Driverless LED strips can be an excellent choice if you want to install long LED strips with AC power. These LED strips come in a single 50-meter length, and you can choose between 110V, 120V, 230V, and 240V voltages.
The 50-meter AC LED strip with power ratings of 110V and 120V can operate without a driver. The only difference between the two is the power rating, but they perform almost the same. However, the 120V LED strip requires less power than the 110V LED strip to emit the same amount of light.
On the other hand, the 230V and 240V versions of the 50-meter driverless AC LED strip are more efficient than the 110V and 120V versions. Due to the long length, these strips are a better choice as they are more effective at mitigating voltage drop issues. As the voltage increases, these strips consume less electricity, making them more efficient.
These LED strips are great for applications where long strips are needed. You can cover up to 50 meters with a single strip, so you don’t have to worry about cutting the strip into pieces or wiring it in line. Additionally, these high-voltage strips emit even, smooth light, making them suitable for a wide range of applications.
The length of available LED strip lights varies based on the manufacturer and type of LED strip. However, the longest LED strip lights can generally be up to 50 meters long. As stated in a previous section, this length is available in driverless AC LED strips with various voltage choices. Longer lengths of constant voltage and constant current LED strips are also available, but they usually top out at around 10-20 meters.
The longest LED strip on the market is 60 meters long at 48V. These extremely lengthy LED strips provide a steady current in the PCB, ensuring that the light output is consistent from one end to the other. Also, these strips prevent voltage drop from being a problem. You can use them indoors and outdoors, and there are various options. These strips are available with a waterproof classification of IP65 or IP67. Features unique to 48V LED strips that are 60 meters in length are as follows:

It can provide bright and reliable lighting for a wide range of uses due to its high efficiency, ease of installation, and wide range of colors and variants available. Furthermore, the IP ratings offered make it suitable for both indoor and outdoor use, making it an all-around lighting solution.
Voltage drop is a common issue with LED strip lights. It refers to the loss of voltage between the power source and the LEDs, mainly caused by the resistance of the wire and the current flowing through it.
Calculating voltage drop is simple:
Voltage Drop = Current x Resistance.
As current flows through the LED strip’s DC circuit, the voltage gradually decreases due to increasing resistance. The higher the resistance, the more significant the voltage drop.
As you extend the LED strip, resistance increases, causing a more considerable voltage drop. This can result in uneven brightness along the strip. The power drop limits the LED strip’s length.
To resolve this issue, increase the power rate as the LED strip lengthens. When the voltage increases, the current decreases and the voltage drop is reduced. This allows for longer LED strips without a noticeable power drop.
Keep in mind that the LED strip length also depends on its thickness and materials. Thicker strips made of higher-quality materials can handle more power and have less voltage drop.
The 48V constant current LED strips can reach up to 60 meters in length. These strips are perfect for large-area lighting projects where ease of installation and uniform illumination are essential. To increase the run length of LED strips, you should consider factors such as voltage drop, power consumption, and PCB thickness. By reducing their power consumption, increasing their output voltage, and choosing thicker and wider PCBs, you can significantly extend the length of your LED strips. The LED strip market offers various voltage, constant current, and driverless AC strips with various lengths and IP ratings. To achieve the best performance and longest lifespan from your LED strip, it’s important to select the right one for your application.
