Many people don’t know what 1-10v dimming is when they hear it. In fact, 1-10V dimming work is a lighting control method. It uses a low-voltage DC circuit between 1 and 10 volts to control the amount of light emitted by the LED in an LED lamp. Currently, 1-10V dimming has become a popular choice for precise and seamless light adjustment. Let’s talk about what 1-10v dimming work is in detail.
What Is 1-10V Dimming?
1-10V dimming, also known as analog dimming, is a widely used lighting control method. It allows for smooth and gradual dimming of LEDs, fluorescent lamps, and other lighting fixtures. For the LED power supply, pls read What Does An LED Driver Do?
The voltage range of 1 to 10 volts corresponds to light output, with 1V representing the lowest intensity and 10V representing the highest intensity. People favor this analog dimming method for its ease of use, reliability, and compatibility with a wide range of lighting systems.
How Does 1-10V Dimming Work?
At it1-10V dimming works by sending a control signal from a dimmer or lighting control system to an LED driver or ballast. When you adjust the dimmer’s slider or use a compatible control interface, it sends a corresponding voltage signal. This signal can range from 1V to 10V. The driver then controls the current flowing to the LED.
- 10V = 100% brightness (full output)
- 5V = 50% brightness (half output)
- 1V = 10% brightness or minimum output (some systems may go as low as 0%)
The system consists of two wires dedicated to dimming:
- Purple wire (positive control signal, 10V)
- Gray wire (negative control signal, 0V referenced to ground)
By adjusting the voltage on these wires, the light output can be adjusted without affecting the power supply to the fixture.
Advantages of 1-10V Dimming
- Precise control: 1-10V dimming offers high precision, allowing for fine-tuning of light levels. Provides consistent dimming with no noticeable flicker, ideal for offices, homes and commercial spaces.
- Simple Control: Dimming requires minimal setup, making it simple and easy to use. Uses low-voltage wiring, reducing the risk of electrical interference and failure.
- Cost-effectiveness: Requires little maintenance and is relatively inexpensive. Ideal for large-scale applications – often used in commercial buildings, theaters, hospitals and industrial settings.
- Compatibility: Works with a wide range of lighting fixtures and works with LED, fluorescent and incandescent lamps.
Disadvantages of 1-10V dimming
- Cost: Compared to other dimming methods, 1-10V dimming work requires a specialized dimmer and LED driver, which increases initial cost.
- Wiring complexity: Installing a 1-10V dimming system requires additional wiring, which can make installation more complicated.
- Interference: In large or complex systems, electrical interference can affect the signal, causing flickering or inconsistent dimming.

Conclusion
1-10V dimming work is a simple, reliable and effective way to control light intensity, and is commonly used in commercial and industrial environments. Although it has its disadvantages, such as lacking the flexibility of digital systems such as DALI, it remains a cost-effective and widely supported dimming option for energy-saving lighting solutions.
FAQs
1-10V dimming is an analog method of controlling lighting that adjusts the brightness of a fixture by varying the voltage between 1V (minimum brightness) and 10V (maximum brightness). It is commonly used for LED and fluorescent lamps and works by sending a control signal to the fixture’s driver or ballast.
The voltage level for 1-10V dimming is adjusted based on the voltage. For example, 10V = 100% brightness (full output), while 5V = 50% brightness and 1V = minimum brightness (usually around 10%). Some systems may go as low as 0V to completely shut down, but this varies by manufacturer.
No, not all fixtures are compatible with 1-10V dimming. The fixture needs to be equipped with a 1-10V dimmable driver or ballast. Many modern lighting supports 1-10V dimming, but it is important to confirm compatibility before installation.
