In it, we will discuss what addressability is and how you can tell if an LED strip has it. We will also provide some tips on how to use addressable LED strips in your next project.If you don’t know how to choose the right addressable LED strip yet, don’t worry.So, without any further delay,Let me explain to you!Let's get started!
Whether you should use the WS2811,WS2812B,WS2815,WS2813,WS2818 will depend on how you plan to use it.
What Is An Addressable LED Strip Light
An addressable LED strip light, also known as a programmable or digital LED strip light, is a type of lighting fixture that consists of multiple individually controllable LED diodes mounted on a flexible strip. Unlike traditional LED strips, where all LEDs light up in the same color and pattern, addressable LED strips allow you to control each LED individually.
Each LED on the strip has its own microcontroller, which can be programmed to display different colors, brightness levels, and patterns. This level of control is made possible by using protocols such as WS2811 or WS2812, which allow communication between the microcontrollers and a central controller, such as an Arduino or a specialized LED controller.
With addressable LED strip lights, you can create dynamic lighting effects, animations, and patterns. These lights are commonly used for decorative purposes, stage lighting, home automation, and other creative lighting applications.
What is difference between addressable LED strip and regular RGB LED strip?
Regular RGB LED strips are composed of a series of LEDs that are wired together and controlled as a single unit, meaning that all of the LEDs in the strip are the same color and brightness and will display the same pattern or effect.
Addressable LED strips have a microcontroller embedded within the strip that allows each LED (each unit) to be controlled individually. This means that each LED (each unit) can be set to a different color and brightness, and can display a unique pattern or effect. The microcontroller communicates with the LEDs using a control protocol, such as DMX512 or SPI, allowing for a wide range of color and animation possibilities.
How Do Addressable LED Strips Work?
Understanding how addressable LED work is critical to having the best lighting design for your project. We’ll keep it simple so you don’t get caught up in too many technical details.
Addressable LED strips let you control each LED (chip) individually, which is made possible by combining an integrated circuit chip (ICs), a controller, and a power supply.
Each LED has its standalone integrated chip (IC) responsible for changing that particular LED’s color and brightness.
The addressable LED strip light is arranged in groups of 3 or 7 chips wired in series. There is a cutting point after each group which is how you can get the desired length of the LED strip.
Next up is a microcontroller that controls each IC of the LED. It does that by utilizing data channels that connect IC with the controllers.
Traditional RGB LED strip doesn’t have controllers with data channels and instead is connected with R, G, B, and + pins that can only send single commands.
All of this is powered by a power supply. It uses a low-power DC supply, typically 12V or 24V.
Moreover, two control protocols, DMX512 and WS2812, are available in the market.
DMX512 is more for professional use, like big light shows, while WS2812 is beginner-friendly and typically used in small-scale projects.
What is WS2811 LED Strip Light?
WS2811 LED strip is an economically addressable led strip controlled by external IC WS2811. Each IC controls 3 LEDs hence every 3 LEDs are cuttable as one single pixel. Each pixel is individually addressable, which makes it very flexible in many applications.
WS2811 Working Principle
The WS2811 IC works by using pulse-width modulation (PWM) to control the brightness of each LED in a string. The IC receives data from a microcontroller, which sends information about the color and brightness of each LED in the string.
The data is sent in the form of a serial signal, with each bit being represented by a pulse of either high or low voltage. The WS2811 IC uses a specific timing protocol to interpret this signal and generate the appropriate PWM signals for each LED.
The WS2811 IC contains an internal shift register, which stores the data received from the microcontroller. The shift register is used to transfer the data to the output stage of the IC, which generates the PWM signals for each LED.
In addition to controlling the brightness of each LED, the WS2811 IC also provides some additional features such as adjustable brightness levels, color correction, and built-in self-test functions. These features make it a popular choice for both hobbyist and commercial LED lighting applications.
Is WS2811 individually addressable?
No, the WS2811 LED driver does not support individually addressable. The WS2811 is a popular external IC used for controlling addressable RGB LEDs, similar to the popular SM16703, RGB LED. Each WS2811 chip can control a group of RGB LEDs and can be programmed to set the color and brightness of that pixel independently of any other pixels in the chain. By chaining multiple WS2811 chips together, it is possible to control entire arrays of RGB LEDs with complex patterns and animations.
What is WS2812B LED Strip Light?
Inside the WS2812B intelligent control LED light source is a package of 5050 parts, including the control circuit and the RGB chip. It has a signal-reshaping amplifier drive circuit, and an intelligently-processing digital port data latch. Also built into the device are a precision internal oscillator and a programmable constant current control element. These parts work together to keep the pixel point light’s color height the same.
In the data transfer protocol, there is only one NZR communication channel. After the pixel has been turned on and reset, the controller will send the data to the DIN port. The first pixel will get the first 24-bit data and send it to the internal data latch. The internal signal of the amplification circuit shapes the other data, which is then sent through the DO port to the next cascade pixel.
After the signal has been sent, it is cut down to 24 bits for each pixel. Pixels use auto-reshaping transmit technology, which means that the number of pixels in a cascade is not limited by how fast the signal can be sent. LEDs run on a low voltage, which is good for the environment and saves a lot of power. They also have a high level of brightness, a wide angle of scattering, good uniformity, low power use, and a long lifespan. The integrated control chip in LEDs is changing to become a circuit with fewer parts, less space, and an easier way to put it together.
What is WS2813 LED Strip Light?
The WS2813 strip light is an updated version of the WS2812B, similar to how the WS2812B is an improved version of the WS2811, but with break continuous function, while one IC is broken, the signal can still pass through.
What is WS2815 LED Strip Light?
WS2815 led strip is an intelligent control LED light source that the control circuit and RGB chips are integrated into a package of 5050 components. Its internal includes an intelligent digital port data latch and signal reshaping amplification drive circuit. Dual-signal wires version, signal break-point continuous transmission. Any pixel’s failure won't affect signal transfer and the total emitting effect.
What is WS2818 LED Strip Light?
the main difference between WS2811 led light strip and WS2818 led light strip is whether it has the function of breakpoint continue transmission and the other performances are the same.
Applications of WS2818 Pixel LED Strip
Due to their versatility, WS2818 addressable LED strips are used in various applications such as:
Home Decoration: WS2818 tape light can be used to create stunning accent lighting, under-cabinet lighting, or even outdoor lights for pathways and patios.
Commercial Lighting: These LED strips are ideal for creating eye-catching displays, signage, and architectural highlights in retail, hospitality, and other commercial environments.
Event and Stage Lighting: These digital LED strips can be used to create dazzling light shows, stage effects, and interactive installations at concerts, festivals, and other live events.
What Is The Difference Between The WS2811 And The WS2812B?
For the WS2811 LED chip to work properly, it needs a voltage of 12 volts. In contrast, the WS2812B chip only needs 5V to operate. When you use an LED strip with many LEDs, the voltage will drop a lot along the length of the strip. This means that the last few LEDs at the end of the strip and farthest from the board will have a lower voltage.
For example, your strip has 30 LEDs, and the voltage drops by 2V near the end. The WS2811 chip will control the rest of the LEDs, and each will get about 10V. For a 12V LED, this is still fine because it was made to work with that voltage. If you use a WS2812B that operates at 5V, the voltage drop you experience will be 3V, not the 5V that is reported. Right there, the voltage has significantly dropped there.
What is breakpoint resume function of SPI addressable led strip?
The breakpoint resume function means that when only one IC fails, the signal can still be passed on to subsequent ICs.
12-Volt vs. 24-Volt LED Strip Lights: What’s the Difference?
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.

How To Know If An Led Strip Is Addressable
There are a few ways to tell if an LED strip light is addressable. Below are a few of the most common ways:
1. Check The Packaging Or Product Description
Many LED strips will list whether or not they are addressable right on the package. If you can’t find this information, check the product website or contact the manufacturer.
2. You Can Also Check The Specifications
If you have an LED strip light and want to check its specs, you can usually find this information in the product manual. Addressable LED strips will list their maximum addressability – for example, how many LEDs they can control at once.
This will typically be stated as a number followed by the letter “M”. For example, a strip with a maximum addressability of 30 LEDs would be written as 30M.
3. Check The Connector Type
Addressable LED strips will typically have a three-pin connector, while non-addressable LED strips will have two pins. If you are not sure which one you have, try to find an LED strip that is similar in appearance and check its connector.
If your LED strip has a three-pin connector, it’s probably addressable. If not, then chances are it isn’t.
4. Look For A Controller Or Remote
One of the easiest ways to tell if an LED strip is addressable is by looking for a controller or remote. Addressable LED strips will come with some type of controller to send commands to the strip. If you don’t have a controller, you can usually find them online or in stores.
These types of remotes are typically used to control the color and brightness of your LED strip. They will allow you to change between colors like red, blue, or green for example – just make sure that it’s compatible with whatever type of LEDs you have installed first.
5. Look At How Many Wires Are Connected
The number of wires connected to your LED strip will determine whether it is addressable or not. If there are three wires, then chances are that you have an addressable LED strip light.
What this means is that each individual LED on your strip can be controlled individually. This allows for more creative lighting possibilities and gives you the ability to create patterns or animations with them.
If there are two wires connected, then it’s likely that your strip light isn’t addressable and will require a controller or remote to function properly.
6. Check The Product Manual
If all else fails, check your product’s user manual. It should say whether it is addressable or not right on the cover page – if not, then look through any other documents that came with it for more information about this topic. If there’s nothing in the manual, contact customer support to find out.
