Dimming is an innovative and flexible way to control light. Dimming lights is another way to save energy and create different moods. LED lighting is a big part of the lighting market and is expected to improve at dimming.
0-10V dimming is an analog method of dimming lighting fixtures that uses a control voltage signal to adjust the light output from 0 to 100%. The control signal ranges from 0 to 10 volts, where the name 0-10V dimming comes from.
Even though LEDs can be dimmed differently, 0-10V dimming is one of the most common ways to control lighting in commercial and industrial settings. If you’re not sure if 0-10V dimming will work for your project. This blog post will give you the answer.
What Is 0-10V Dimming?
0-10V dimming is a way to control how bright the light is. It works on direct current voltage (DC) between 0 and 10 volts. The easiest way to control lighting is with 0-10V dimming, which allows for smooth operation and dimming down to 10%, 1%, and even 0.1% light level.
At 10 volts, the light will be at its brightest. At 0 volts, the light will dim to its lowest level, but a switch is sometimes needed to turn it off completely.
This easy-to-use lighting control system can be connected to LED lights for various lighting options and moods. Using a 0-10V dimmer, you can create lighting that fits your mood or activity by adjusting the brightness level. For example, making areas like bar and restaurant seating feel more elegant.
History Of 0-10V Dimming
0-10V dimming systems are also called fluorescent dimming systems or five-wire dimming systems. This dimming system was created when large systems needed a flexible way to turn down lights with magnetic and electrical blasts. So, all the lights can be turned down at once without changing anything but the bulbs. At the time, a 0-10V dimming system solved the big companies’ problem.
These 0-10V dimming systems are still used, but as everything else in the world improves, these dimmers are becoming more popular with the newest and best lighting products such as LEDs.
The International Electrotechnical Commission (IEC) standard number 60929 Annex E is why this system is so well-known and widely used. Most companies and engineers agree with this standard.
How Does 0-10V Dimming Work?
LED drivers with 0-10V dimming have a circuit with a purple and gray wire that makes a 10V DC signal. When the two wires are open and don’t touch each other, the signal stays at 10V, and the light is at 100% output level.
When the wires are touching or “shorted” together, the dimming signal is at 0V, and the light is at the lowest level of dimming that the driver has set. 0-10V dimmer switches lower the voltage or “sink” it so the signal can go from 10V to 0V.
Usually, the DC voltage matches the level of dimming of the driver. For example, if the signal is 8V, the light fixture is at 80% output. If the signal is turned down to 0V, the light is at its dimmest level, which could be between 10% and 1%.
Where To Use A 0-10V Dimmer?
0-10V dimming was made as a standard way to control fluorescent lights with light-dimming ballasts, and it is still often used in this way. With recent improvements in LED technology, 0-10V dimming has become a reliable and widely used way to control how dim LED lights are.
This system can dim LED fixtures in retail stores, office buildings, entertainment venues, theaters, and other commercial spaces. 0-10V dimming can also be used for commercial applications outside that need lighting that can be used for more than one thing. LED high bays, LED flood lights, LED strips, LED neon, and LED retrofit kits, to name a few, can be turned down.
Dimmable fixtures are often chosen for their ability to change the mood, but there are other reasons to use this type of lighting control system.
0-10V Dimming vs. Other Dimming Systems
There are several types of dimming systems available in the lighting industry, each with its own advantages and disadvantages. 0-10V dimming is a simple and widely used analog dimming technology that is compatible with many lighting fixtures and control systems, but has a limited control range and is susceptible to interference and noise. Other dimming technologies, such as DALI, PWM, wireless, TRIAC, and DMX, offer different benefits and drawbacks. For example, DALI provides precise and individual control of each lighting fixture, but can be more complex and expensive to install and operate than other systems. PWM provides flicker-free and efficient dimming for LED lighting applications, but may require special control equipment. Wireless systems offer flexible and easy installation, but may be susceptible to interference and hacking. TRIAC dimming is simple and low-cost, but can produce audible humming or buzzing. DMX provides flexible and programmable control, but requires specialized control equipment and software. A comparison of these different dimming systems can be seen in the table below:

What Do I Need For 0-10V Dimming?
Because of how LEDs work and how some drivers are made, not all LED drivers can be used with 0-10V dimmers. Ensuring your fixture has the right parts for a dimmer to work is essential.
In some cases, all you have to do to make an existing fixture dimmable is switch out the driver. In recent years, LED technology has come a long way, and now most commercial LED fixtures can be dimmed. Once you know if your fixture is compatible, you will need to run low-voltage wiring from the fixture back down to a compatible wall switch.
Are There Recommended Wiring Practices For 0-10v Dimming?
Your fixture’s driver can be a class one or a class two circuit, which means it either has no safety protection warnings or a significant safety protection warning.
When working with a class one circuit, it is important to handle the high-voltage output safely. Because the power is limited, there is no chance of getting an electric shock or starting a fire with a class two circuit driver. However, class one is often the most efficient because it can power more LEDs.
The source (driver) is usually connected to the dimming signal, which has a purple wire for +10 volts and a gray wire for the signal. When neither wire touches the other, the dimmer output will be 10 volts or 100%.
When they touch, the output from the dimmer control will be 0 volts. Its lowest level is 0 volts, and depending on the driver, the fixture will either go into sleep mode, turn off completely, or use a dimmer switch to turn it off.
It is best to keep the distance between the analog control wiring and the driver as short as possible when installing power or analog controls. As the National Electric Code requires, keeping all class two control circuits separate from class two line voltage wiring is essential.
The separation is vital because wiring with a higher voltage can send alternating current voltage to signals with a lower voltage. This can cause unwanted effects and safety problems with dimmed lights.
How To Install A 0-10V Dimming System
Here are the steps to install a 0-10V dimming system:
- Select the right tools: You’ll need a 0-10V dimming driver, a dimmer switch that works with the driver, and LED lights that work with the dimming system.
- Turn the power off: Turn off the power to the circuit you’ll be working on before you start the installation.
- Join the power source and the LED lights to the dimming driver.
- Connect the switch for dimming to the driver for dimming.
- Check to see if the system is working right.
Make sure to follow all the safety rules and instructions with your gear. Best wishes for your installation!

- Test the system: Before you use it, ensure it works right by testing it. Check that the dimming range is smooth and even and that the lights don’t buzz or flicker.
- Use appropriate loads: Only use loads that are right for the dimming system. Don’t put too much load on the system, like too many lights or a big load.
- Control voltage drop: Keep an eye on voltage drops, which can happen over long distances or when using multiple loads. Use the proper wire sizes and follow the instructions in the equipment manual or from the manufacturer.
Using these best practices, you can ensure your 0-10V dimming system is safe, reliable, and meets your needs.
Troubleshooting 0-10V Dimming Systems
0-10V is easy to troubleshoot compared to other ways of dimming, let’s take a look at various issues that may appear with 0-10V dimming and how you can fix it.
- Driver And Dimmer Issues
If the light fixture doesn’t work well with a dimmer, the dimmer or driver may be broken. First, make sure the driver functions as it should. The dimmer and LED driver are connected by two low-voltage control wires.
Take the wires out of the circuit and briefly touch two of them together. If the light goes down to the lowest brightness level, the driver is fine, and there may be a problem with the dimmer or the wires. If not, the driver isn’t working how it should. You could fix the problem if you changed the driver.
- Noise Due To Wires Issues
If the light fixture makes noise when you turn it up or down, pay attention to the wires. The AC power cables near the 0-10V DC wires may be making noise. A dimming fault will also happen if the wires aren’t correctly positioned.
The problem could be caused by the fact that the 0-10V DC wires are near AC wires or are put in the same conduit as AC wires. The noise is often a sign that the installation was wrong, so we should check to see if the light-dimming system works properly after the first installation.
- Improper Dimming Range
Not all 0-10V dimmers can give drivers the full range of 0-10V because some dimmers may not be compatible with drivers. Make sure the dimmer works with the driver by looking at the lists of compatible dimmers that the driver manufacturers and the light fixture have made.
When you connect 0-10V dimmers to a 1-10V driver, flickering, stuttering, and flashing will happen in low dimming control. The problems are easier to see when the on-off setting is used. The light fixture can’t be turned off entirely without cutting power.
Adding 0-10V dimming to a lighting system can change the light intensity, and less energy is used.
