LED Strip Lights – Everything You Need to Know

LED strip lights offer a versatile and customizable lighting solution for lighting homes, businesses and outdoor areas. However, there are many technical details in lighting solutions that are worth considering before making a purchase decision. This guide covers the different types of LED strip lights, color tones, power, control methods, installation profiles, pointless strips and transformers, so that you can find the perfect solution for your needs. There is a lot of choice in LED strip lights for different purposes. The properties of the strips vary, for example, according to brightness, color, controllability and moisture resistance. Choosing the right strip depends on the purpose and space for which it is installed. For example, a warm-toned, dimmable strip may be suitable for mood lighting, while a more efficient and cooler light is needed for task lighting. There is a lot of choice in LED strip lights for different purposes.

What type of LED strip should I choose? Monochrome, dimmable, RGB or dotless?

There are several different types of LED strip lights available. Your choice depends on the kind of atmosphere or lighting effect you want to create in your space.


Single-color LED strips


Monochrome strips are simple and effective lighting solutions that provide a single white color tone. They are perfect for general and task lighting, and are usually available in different color temperatures: warm white (2700K–3000K), neutral white (4000K) and cool white (5000K–6000K). Monochrome strips are an excellent choice for lighting kitchen countertops, work areas and bathrooms, for example, where uniform and bright lighting is important.


Color Temperature Adjustable (CCT) LED Strips

CCT strips allow you to adjust the color temperature of the light from warm to cool white. This means you can customize the tone of the light to suit your situation and needs. For example, a warmer tone can be used for relaxation and a cooler white for working. CCT strips are ideal for spaces where the lighting needs to adapt to different moods or functions, such as a living room or bedroom.


RGB, RGBW and RGB+CCT LED strips

With multi-colored RGB LED strips, you can create colored lighting. RGB strips have a combination of red, green, and blue, which can be used to create a wide range of colors. RGBW strips also have a separate white LED, which makes them more versatile: you can go from colorful lighting to traditional white lighting. RGB+CCT strips combine both color options and color temperature adjustability, giving you full control over the look and feel of your lighting.

Number of LEDs per meter – How dense an LED strip should you choose?

The light output and uniformity of LED strips depend on the number of LED dots in the strip. The denser the LEDs are installed, the more uniform and brighter the light is.


30 LEDs/m : Suitable for background lighting and applications where strong light output is not required.

60 LEDs/m : A good compromise between even and bright light. Suitable for general and accent lighting.


120 LEDs/m or more : Very even and bright light, suitable for lighting work surfaces and workstations, for example.


COB LED strips : The dense LED installation ensures completely spot-free light. These strips are used when a completely uniform light surface without LED spots is desired.


Dotless COB LED strips

COB (Chip on Board) technology enables very densely placed LED dots, resulting in a uniform and spot-free light. This feature makes COB strips very pleasant to use and gives the light a soft, uniform look. Spot-free COB LED strips are an excellent choice for areas where the strip is installed in a visible position or where spot-free lighting is particularly important, such as mirror lighting, countertop lighting or decorative lighting.

Light brightness and color temperature

The brightness of an LED strip light is expressed in lumens, which describe the amount of light. The choice of brightness depends on the space and lighting needs:



  • 200–500 lm/m : Sufficient for mood lighting and background lighting.

  • 500–1000 lm/m : Suitable for accent lighting and spaces where moderate light output is needed.

  • 1400 lm/m or more : A good choice for workspaces, kitchen countertops, and other task lighting.


Color temperatures or Kelvins


Color temperature affects the tone of the light. Warm white (2700–3000K) provides a soft and cozy light, neutral white (4000K) works for general lighting and more modern lighting, and cool white (5000–6000K) is suitable for spaces where precise and bright lighting is needed. Color temperature adjustable (CCT) LED strips allow you to adjust the color temperature according to your needs.

LED strip light according to installation location

Waterproof LED strips (IP65 or IP67) are ideal for damp and wet spaces, such as bathrooms, saunas and outdoor use. IP20-rated strips can be used indoors. Ensure the conditions of the installation site and choose the appropriate protection class for the strip so that it can withstand the requirements of the space. Valotehdas LED light strips have options for every space:



  • For indoor use – IP20-rated strips are suitable for living rooms, bedrooms and other dry spaces.

  • For wet areas – IP65 strips are water resistant and suitable for bathrooms and kitchens.

  • For outdoor use and pools – IP67 strips withstand demanding conditions and can be installed in outdoor areas and shower pools, for example.

Profile selection – the impact of the LED profile on the appearance of the light

LED profiles improve the appearance of the LED strip, protect it and ensure a more even light distribution. The right profile increases the durability of the installation and allows for a neat finish. The height and type of profile affect whether the LED dots are visible and how the light is distributed in the space. The following factors influence the choice of profile:



  • Installation location and space : The type and height of the profile should be chosen according to the space and intended use.

  • Aesthetics and purpose : If the LED strip is visible, a higher profile makes the light more even and softer.

  • Cost : The choice of profile is also influenced by budget, as different profile types can differ in price depending on the structure and materials.


Profile types


Surface profiles
Surface profiles are popular because they can be attached directly to the mounting surface. This type of profile is easy to install and is well suited for spaces where the LED strip does not need to be recessed or hidden, such as kitchen countertops, shelf bases and ceiling ledges.


Countersunk profiles
Recessed profiles are recessed into the surface, allowing them to blend seamlessly into, for example, ceiling or wall panels. Recessed profiles create a clean and unobtrusive look, and are particularly suitable for minimalist spaces. They require more installation work, as the installation surface often has to be cut to the profile dimensions. Recessed profiles are an ideal solution for applications where the light is desired to be even but unobtrusive.


Corner profiles
Corner profiles are designed to be installed, for example, in the corners of cabinets or on the edges of walls and ceilings. Corner profiles usually distribute light at an angle of 45 degrees, which makes them an excellent choice for areas where you want to direct light in a specific direction. Corner profiles are well suited, for example, for workspaces or display windows where you want to focus light on a specific point.

Profile height and LED dot visibility

The height of the profile affects whether the LED dots are visible or not, which is especially important for strips with a low number of LED dots:



  • Slim profile : A slim profile works well when the LED strip is hidden or the visibility of the LED dots does not detract from the appearance of the lighting, or when using COB LED strip lights without dots. A slim profile is also a stylish option, but with it the LED dots can remain visible unless the strip has a large number of LEDs.

  • 12x12 mm MINI10 profile : This taller profile is ideal for 120led/m strips, as its height significantly reduces the visibility of the LED dots and evens out the light. The profile creates a clean and uniform look even when the strip is on display.

  • COB strip profiles : COB LED strips are spot-free even in thin profiles because the LED dots are placed very densely. This makes them ideal when you want a completely flat light surface without a high profile. COB strips are also suitable for low profiles and situations where installation space is limited but uniform and spot-free light is desired.

Choosing a transformer – Which transformer is suitable for LED strip lights?

The right transformer is an important part of the functionality and durability of your LED strip light. Choose a transformer that matches the voltage and control needs of your strip. The transformer's power reserve should be about 20–30% higher than the calculated power requirement of your LED strip. This will help keep the transformer cool and extend its lifespan.



For example, if the power of the strip is 12 W/m 24V and its length is 5m, the required power is 60W. In this case, it is worth choosing a transformer of at least 75W 24V or higher.



  • A 12V transformer for a 12V strip and a 24V transformer for a 24V strip : The voltage of the transformer must match the voltage of the LED strip.

  • Basic transformer (on/off or wireless control) : Suitable if the strip is controlled simply by turning it on and off or by a wireless controller. In wireless control, the controller is connected to the secondary side of the transformer.

  • TRIAC dimmable transformer : If you want to control your LED strip with a traditional wall dimmer, choose a TRIAC dimmable transformer. This allows for stepless dimming directly from the wall dimmer.

  • IP-protected transformers: If you install the transformer outdoors or in a bathroom, the transformer must be moisture-proof.


LED strip light control options

LED strip control options vary depending on the type of strip. Single-color strips can be connected to a simple dimmer, while CCT and RGBW strips require a special controller. RGB+CCT strips allow you to adjust the color temperature and colors of the light separately, which provides more possibilities to create the desired atmosphere. LED strip lights can be controlled in many different ways, and choosing the right control system depends on your needs and the technical requirements of the space. Here are the most common control options:



  • Traditional dimmers and TRIAC dimmable transformer : A simple control solution that is suitable if you want to dim the LED strip with a standard wall dimmer. In this case, a TRIAC-compatible transformer is required.

  • DALI control : DALI (Digital Addressable Lighting Interface) is a lighting control system that enables precisely adjustable and centrally controlled lighting. It is an excellent choice for large spaces or professional applications where versatile lighting settings are required.

  • Zigbee Control : Zigbee is a wireless protocol used in smart lighting. A Zigbee-compatible LED strip can be connected directly to a smart home system and controlled wirelessly via a mobile app or voice control. Zigbee is ideal for homes with multiple smart devices and a desire for flexibility in control.

  • Miboxer 2.4G series : Miboxer offers a wireless control system that operates at 2.4 GHz. The system is easy to install and connect to various Miboxer controllers, and is compatible with most LED strips. Miboxer is a good choice if you want simple and functional wireless control without complicated installation.

  • RF WiFi Series with Glass Backed Dimmers : Sunricher offers high-quality glass backed dimmers that are not only stylish but also easy to use. They are compatible with multiple control protocols and are suitable for interior-conscious environments where both appearance and functionality are important.


These control options allow you to control the brightness, color temperature, and color tones of the LED strip light according to the requirements of your space.
