As their use has grown, so have the variations, introducing subtly named counterparts such as RGBW and RGBWW, which have added to the buying complexity. We aim to examine the sophisticated elements of these lighting systems, including their design, functional range, and the principles of color theory that justify their extensive application across diverse design settings.

In this detailed guide, we’ll demystify RGB and RGBW strip lights, highlighting the distinct features and advantages RGBW technology brings to elevate your lighting experience.

Understanding LED Strip Lights

These strips consist of small light-emitting diodes (LEDs) arranged in a linear sequence on a flexible circuit board, also known as ribbon or tape lights, which are versatile and energy-efficient lighting solutions. Due to their slim design and adhesive backing, they can be installed in various locations, offering decorative and accent lighting options for residential and commercial spaces.

What are LED Strips?

LED strips are flexible circuits populated with multiple LEDs that you can use to add powerful lighting in a discreet, clean-looking way. They are customizable, often able to be cut to specific lengths, and come in various color temperatures and brightness levels. Most LED strips work with dimmers and controllers to adjust the light intensity and can even be made bright with the integration of home automation systems. They are also available in waterproof versions for outdoor or bathroom use.

Types of LED Strip Light

Addressable RGB LED Strip Lights

Traditional RGB LED strips can illuminate any color of the rainbow but are limited to showing a single color at any moment. The RGB controller can switch the colors, yet it cannot manipulate individual LED modules.

Conversely, Addressable RGB (ARGB) LED strip lights have the technology to display several colors simultaneously. Each LED functions as a discrete lighting unit, providing the flexibility to craft complex and dynamic color patterns.

ARGB strips are frequently utilized in computer hardware enhancement, offering compatibility with intelligent control hubs for creating diverse and intricate lighting displays.

Comparing the two, while standard RGB LED strips can produce a range of colors, they only exhibit one color at a time. ARGB strips showcase multiple hues simultaneously, allowing for gradients and transitions akin to a cascading rainbow.

Examining Diodes and Channels

A diode is an electrical component that produces light as electric current passes through it. The specific color it emits is a function of the materials from which it is constructed since these materials generate light at varying wavelengths upon receiving electrical energy.

Channels represent a finer classification within a signal diode. An RGB LED houses a combination of semiconductors that carry three primary colors — red, green, and blue — within a single diode. These three elementary color elements are known as channels, and specific LEDs are engineered with additional channels beyond the standard three.

Different Types of RGB LED Strip Lights

RGB LEDs offer a versatile palette for color customization. The LED modules within strip lighting have several variations that significantly affect the hue and luminosity of the emitted light. Here are some of the most widely embraced variations of RGB strip lighting.

RGB LED Strips
rgb led strip lights

RGB LED strip lights are LED lighting that can produce a broad spectrum of colors. The ‘RGB’ stands for Red, Green, and Blue—primary colors of light that can be combined in varying intensities to produce over 16 million light hues. These strips typically contain three LEDs in each lighting unit, one for each primary color. They are controlled via a handheld remote, a smartphone app, or a dedicated control unit, which you can use to customize the color output according to your needs.

An RGB LED is a type of light that combines red, green, and blue light-emitting diodes (LEDs). Each diode can shine with an intensity measured on a scale from 0 to 255, allowing for fine-tuning color output. By modulating the brightness levels of the red, green, and blue LEDs, one can blend them into a broad spectrum of colors, unlocking the ability to craft more than 16 million distinct shades.

To produce a pure blue color, the RGB LED would be set to full intensity for the blue diode (255) while keeping the red and green diodes off (0). To create purple, you would reduce the green to zero and adjust the red and blue to higher values. White is achieved by having all three diodes—red, green, and blue—operating at full intensity (255).

An RGB LED strip consists of numerous small RGB LEDs mounted in a linear arrangement on a flexible strip, allowing easy placement and installation. The strip is accompanied by a controller, which can regulate the color settings. Some controllers also offer advanced features, including wireless control from a remote, smartphone, or integration with a smart home system.

These low-voltage strip lights, typically 12 or 24 volts, necessitate a separate power source. LED strips present a versatile solution adaptable to various needs, ranging in voltage, luminosity, design, length, and moisture resistance, making them ideal for creating ambient and mood lighting in different environments.

How do RGB LED Strip Lights Work?

RGB LED strip lights operate on the principle of color mixing through light emission from tiny, densely arranged light-emitting diodes (LEDs) in red, green, and blue hues. Each LED on the strip can project red, green, or blue light. Using additive color mixing, the primary colors are blended at different intensities, creating a broad spectrum of other colors, even white.

The functioning of RGB LED strips typically involves the following components and steps:

Power Supply: The strip lights are powered by a low-voltage DC power source, usually 12V or 24V, provided by an adapter connected to your main power supply.

LED Chips: These are the core components that emit light. Each chip on an RGB strip contains a red, green, and blue diode. By varying the voltage to each diode, the intensity of each color can be controlled.

PCB (Printed Circuit Board): The strip has a flexible printed circuit board on which the LEDs are mounted, allowing the strip to be flexible and bend around corners or conform to surfaces.

Resistors: Small resistors are included in the circuit to manage the current reaching each diode, ensuring that they do not burn out prematurely.

Controllers: An RGB controller is connected to the strip and is the command center for controlling color and light intensity. Some controllers can handle multiple channels for various strips simultaneously.

User Interface: This can be a physical remote control, a smartphone app, or a voice-activated device in smart home setups that allows the user to adjust the color, brightness, and sometimes the pattern or speed of color change.

Color Mixing: When activated, the controller sends signals to adjust the brightness of each color. For instance, if more blue and red light are emitted, the strip will appear purple. This additive mixing allows for the creation of a full spectrum of colors.

Adhesive Backing: The backside of the strip usually comes with an adhesive, allowing for easy installation in various locations such as under cabinets, along baseboards, behind televisions, and more.

What are Some Typical Applications for RGB LED Strip Lights?

RGB LED strip lights are incredibly versatile and can be used for various applications due to their flexibility, color variety, and ease of use. Here are some common uses:

How do RGB LED Strip Lights Create Different Colors?

RGB LED strip lights create different colors through additive color mixing, utilizing the primary colors of light: red, green, and blue. Each LED on the strip contains three separate light sources for these primary colors. By adjusting the intensity of each of these colors, a broad spectrum of colors can be produced.

The principle behind this is that when light colors mix, they add up to create other colors. For example:

  • Red + Green = Yellow
  • Green + Blue = Cyan
  • Blue + Red = Magenta
  • Red + Green + Blue (all at full intensity) = White

The specific color produced by an RGB LED strip is determined by the intensity (brightness) of each red, green, and blue LED within an individual light unit. Each color can typically have its intensity adjusted on a scale from 0 to 255. Using a controller, you can create over 16 million color combinations by varying these levels. For instance, to get a pure red color, you would set the red LED to its highest intensity (255) and the green and blue LEDs to its lowest intensity (0).

Dimming or brightening each color in different combinations creates a vast array of colors, providing versatile lighting options for various applications.

Can RGB LED Strip Lights be used for Outdoor Lighting?

Yes, RGB LED strip lights can be used for outdoor lighting, but ensuring they have the appropriate weatherproofing is crucial. When selecting RGB LED strip lights for outdoor use, you should consider the following factors:

How do RGB LED Strip Lights Achieve the IP65 Rating for Outdoor Use?

RGB LED strip lights to achieve the IP65 rating for outdoor use through various protective measures. The acronym “IP” stands for Ingress Protection, with the subsequent two numbers indicating the degree of defense against solids (first number) and liquids (second number).

Here’s each the rating achieved:

Solid Particle Protection (6): The first digit, 6, indicates that the LED strips are entirely dust-tight. This is typically accomplished by enclosing the strips in a solid, impenetrable casing or sleeve that prevents dust particles from entering and potentially damaging the electronic components.

Liquid Ingress Protection (5): The second digit, 5, signifies that the lights are protected against low-pressure water jets from any direction. This level of protection is usually obtained by sealing all joins and edges in the casing with waterproof materials like silicone or specialized gaskets, ensuring that water cannot penetrate these vulnerable points.
The installation process adheres to the manufacturer’s to maintain the integrity of the protective measures that give the LED strip lights their IP65 rating.

What Factors Can Cause Damage or Fade to RGB LED Strip Lights?

Several factors can cause damage to RGB LED strip lights or lead them to fade over time:

Water and Moisture: Even with an IP65 rating, moisture can seep into the LED strip and cause damage if the sealant wears off. Extended contact with water or persistent high humidity levels can lead to the corrosion of the components.

Sun Exposure: Constant exposure to the sun’s UV rays can lead to the degradation of materials and can cause the colors of the LED strip lights to fade.

Physical Damage: Rough handling during installation, improper mounting, or impact from external sources can physically damage LEDs or their circuitry.

RGBWW LED strips incorporate a warm white channel alongside the classic red, green, and blue ones, offering a cozier white hue that many find more appealing for interior illumination.

  • Advantages of Warm Lighting

While cool white light, featuring a bluish tone, aids concentration and is often the choice for work environments, warm white light, with its yellowish tint, creates a more inviting atmosphere. It’s gentler on the eyes and minimizes the starkness of illumination. Incorporating a warm white channel softens the overall light effect.

  • Clarifying RGB Terminology

There needs to be a shared understanding of what RGBWW means. It signifies red, green, blue, and warm white—not to be confused with the notion that it includes both white and warm white.

For outdoor lighting at night, the softer glow of RGBWW LED lights is favored for its subdued quality compared to stark, cool white light.

Restaurants predominantly opt for warm white LEDs in interiors and exteriors, aiming for a welcoming ambiance.

The term RGBW+WW might surface, suggesting a light with two types of white channels. However, this is typically a misnomer for RGBCW LED strips, often needing to be correctly identified.

RGBCW LED Strip Lights
rgbcw led strip lights

RGBCW LED lights feature a sophisticated five-channel configuration that includes cool and warm white LEDs, offering an extensive range of color temperature selections.

  • Identifying RGBCW LEDs

To distinguish RGBCW LEDs, look for a small yellow patch for the cool white LED and an orange dot for the warm white LED on the diode. This color difference on the diode’s surface denotes its capability to deliver varying shades of white light.

  • Structural Differences

Specific RGBCW LEDs have a composite structure, integrating an RGB diode for vibrant color mixing and a CW diode to adjust white light temperature between cool and warm tones.

RGBCW LED Strip Lights

  • RGBCW is an acronym that combines Red, Green, Blue, Cool White, and Warm White in a single lighting system. These strip lights have two white LEDs: one for emitting cool white light and another for warm white light.
  • The user can choose between cool white (a bluish-white light) and warm white (a yellowish-white light) but cannot blend the two to create intermediate white light temperatures.
  • RGBCW allows for color changes and the selection of either cool or warm white light but does not offer a gradient between these two white color temperatures.

RGBCCT LED Strip Lights

  • RGBCCT incorporates Red, Green, Blue, and Correlated Color Temperature control for white light.
  • The CCT in RGBCCT allows users to blend the cool and warm white LED outputs, enabling them to achieve a wide range of white light temperatures along the spectrum from cool to warm.
  • This offers much more precise control over the shade of white light, which can be fine-tuned to specific Kelvin ratings depending on the desired ambiance.
  • RGBCCT strip lights typically come with controllers or apps that permit users to adjust the white light temperature seamlessly, creating customized lighting environments with greater precision.

What Are the Advantages of RGBCCT LED Strip Lights over RGBCW LED Lights?

The advantages of RGBCCT LED strip lights compared to RGBCW LED lights lie in their advanced capabilities for color temperature control and customization:

RGBIC LED Strip Lights
rgbic led strip lights

RGBIC stands for RGB Independent Control, indicating a system where each LED on the strip is governed by its intelligent control chip. This setup enables individual manipulation of each diode in an RGBIC LED strip light.

For those who have spotted the similarity, RGBIC essentially serves the same function as addressable RGB lighting, acting as the more technical term for programmable red, green, and blue light systems.

Innovative Lighting Possibilities

RGB LED strip lights can program various patterns, display rainbow sequences, and seamlessly transition through different lighting effects. However, a limitation of these strips is their inability to be cut to size or re-sized like standard RGB LED options, restricting installation flexibility.

Moreover, integrating an IC (Integrated Circuit) chip into each LED dramatically adds to the expense of RGBIC light strips. Setting up numerous RGBIC LED installations requires smart LED controllers, further elevating the overall cost of the lighting system.


RGB strip lighting is a versatile and cost-effective option for those seeking to add color to their environments. Nonetheless, specific applications are limited in their capacity for customization and the vibrancy of their hues.

Various enhancements to RGB technology have emerged to address these constraints, supplementing the traditional setup with extra color channels and intelligent controls.

Deciding Between RGB and RGBW

When juxtaposing RGB with RGBW LEDs, both their counterpart by offering:

  • Enhanced brightness
  • A purer and more authentic white illumination

While RGB strips are a more budget-friendly choice, RGB serves similar functions in providing accent lighting; however, RGBW surpasses LEDs, significantly improving light quality for a comparable price.

What Sets RGBW LEDs Apart?

The distinction between RGBW and RGB LEDs lies primarily in two aspects:

  • RGBW LEDs have a stronger luminosity
  • They can produce a much more accurate and lifelike rendition of white light

The Value of RGBW LEDs

Given their superior brightness and chromatic accuracy capacity, RGBW LEDs represent a valuable upgrade. Offering better light quality at a price point not far off from conventional RGB LEDs, investing in RGBW strip lights is indeed a worthwhile consideration.

Color Temperature

LED light color temperature spans from chilly to cozy shades, assessed on a Kelvin scale extending from 1,000K to 10,000K. This temperature gauge determines whether the light appears warm or cool to the observer.

  • At the highest end of the scale, 10,000K resembles the crisp, vibrant sky color on a sunny day.
  • Towards the lower end, around 1,900K, LEDs give off a soft glow akin to candlelight’s warm amber tones.

Warm light creates an inviting and tranquil atmosphere conducive to relaxation. Conversely, light with a cooler temperature promotes concentration and alertness. Still, it may adversely affect one’s natural sleep-wake cycle if used excessively during evening hours, as it can be mistaken by our brains for daylight, thus disrupting our circadian rhythms.

Regularly adjusting between cooler and warmer lighting can significantly enhance inhabitants’ ambiance, comfort, and overall well-being in residential and professional settings.

Despite being pricier, RGBCW (combining cool and warm whites) and RGBWW (adding a warm white to RGB) LED options are often preferred for their versatility and the enhanced quality of light they offer.

RGB Controller

Without a controller, RGB lighting lacks the functionality that makes it stand out. These controllers act as the intelligence behind the system, much like a brain, while the diodes serve as the functional body.

Two key accessories are essential for operating RGB LED light strips: a power supply unit and a controller. The controller’s role is pivotal; it adjusts the strip’s brightness and alternates among colors, visual effects, and dynamic patterns. Once LED strips are in place, interaction with them is exclusively through the controller.

Controllers have evolved to offer both hardwired and wireless means of managing lighting. Wired setups might include a manual dial fixed to a wall or a sophisticated digital interface that integrates with home automation systems.

Primary RGB controllers typically utilize IR technology for wireless control, employing a remote to alter the lights’ colors and power state. On the pricier end, some controllers feature Wi-Fi connectivity, allowing users to manipulate their lighting via a dedicated app on their smartphones.

RGB LED Strip Lights Voltage

Let’s delve into LED light strips’ electrical specifications and power requirements. RGB light strips on the market typically operate at 12 or 24 volts. With 12-volt LED strips, a slight voltage drop over extended lengths restricts them to a maximum run of 5 meters.

Voltage Drop

Voltage drop is a natural phenomenon in LED setups and happens due to the accumulating electrical resistance within the copper wiring as the distance from the power source increases. To mitigate this, 24-volt RGB strips are used; they offer excellent dependability and can span lengths up to 10 meters without significant voltage loss.

For installations exceeding 10 meters, sturdier RGB LED strips that operate between 48 and 120 volts are recommended. Conversely, for more modest needs, there are 5-volt LED strips that draw power via a USB port. Although convenient due to their compatibility with USB power sources, they compromise on maximum brightness and the length of the strip compared to their higher voltage counterparts.

Tips when You Choose RGB LED Strip Light

When choosing an RGB LED strip light for your home, commercial space, or outdoor area, weighing several crucial considerations is essential.

  • Functionality

The intended use is the primary determiner in your selection process. For decorative accents or mood lighting, a bare RGB strip may suffice. But if you need the lights to double as a primary illumination source, consider RGBW/RGBW/RGBCW options, as they include white light channels for a fuller spectrum. For evening outdoor setups like a restaurant’s patio, RGBWW strips might be ideal, providing a cozy glow.

  • Cost

Prices for RGB LED strips can differ significantly depending on their build quality, length, technological features, adhesive strength, and waterproof capabilities. The sequence from the most affordable to the costliest generally follows this pattern:

Standard RGB Strips < RGBW/RGBWW Strips < RGBCW Strips < RGBCCT Strips < RGBIC Strips

  • User Experience

The control mechanism for your LED lights should offer convenience and ease. Options like smartphone app connectivity or a universal remote can enhance the user experience significantly. RGBIC and RGBCCT strips are top picks for effortless operation and setup.

  • Power Supply Requirements

The cost of power adapters can exceed that of the strip lights due to the need to convert standard 120v (North America) or 240v (Europe) mains electricity to the 12v or 24v required by LED strips. More extended LED arrangements will need more robust power solutions.

  • Durability

Today’s RGB LED strips are efficient and can operate for extended periods without issue. Still, they are vulnerable to environmental factors such as moisture and power surges. Opt for higher-end strips with quality components and waterproof coatings to enhance longevity and mitigate the risk of damage.


RGB and RGBW LED strip lights represent only a starting point in RGB lighting technology’s extensive and fascinating realm.

Various RGB lighting alternatives have been developed to address the limitations inherent in traditional RGB LED strips.
