24V lighting

24V lighting is a widely used lighting technology, especially in applications where energy efficiency , long cable runs , and better control over light distribution are important. This type of lighting is often used in LED lighting , such as light strips , recessed spotlights , outdoor lighting , and architectural lighting . Below, I explain in detail what 24V lighting is, its advantages, applications, and considerations when choosing 24V lighting.

What is 24V lighting?

24V lighting operates on a 24-volt direct current (DC) power supply, unlike the more common 230V alternating current (AC) system found in households. These lights are often powered by a transformer or driver that converts the 230V AC power to 24V DC to power the lamps.

Advantages of 24V lighting:

  1. Lower voltage drop over long distances :
    • The biggest advantage of 24V lighting over 12V lighting is the lower voltage drop over long cable runs. Because 24V requires less current for the same power, there is less loss through the cables, even when the lighting needs to be powered over longer distances.
    • This makes 24V systems ideal for larger installations or applications where lighting is distributed over a larger space or long distances.
  2. Higher energy efficiency :
    • Due to the lower voltage drop and improved power distribution , 24V systems are often more efficient than 12V systems, especially in applications with longer cable runs.
    • The lower energy loss results in less heat generation and a longer lifespan of the lighting.
  3. More flexibility in installation :
    • 24V lighting can easily be used for various lighting configurations, such as LED strips , recessed spotlights , or sophisticated architectural lighting . Because the system requires less power, larger lighting systems can be installed more easily with thinner cables .
    • This offers more design possibilities for lighting designs that require more flexibility and control.
  4. Better light quality and uniformity :
    • 24V systems often offer better uniform light distribution, especially over long distances. This ensures more consistent illumination and prevents dark spots from forming in the lighting.
    • In combination with LED technology, the colour rendering (Ra) and light output of 24V lighting can be of high quality, which is important for both functional and decorative lighting .
  5. Safety :
    • Because 24V lighting operates at a lower voltage than the usual 230V AC systems , it is considered safer to install and use, especially in environments such as bathrooms , kitchens , outdoor lighting or vehicles .

Applications of 24V Lighting:

  1. LED Light Strips :
    • 24V LED strips are ideal for applications requiring long distances, such as architectural lighting , ceiling lighting , or wall lighting . The lower current helps minimize light losses , even over longer lengths of strip.
  2. Outdoor lighting :
    • 24V lighting is widely used in outdoor lighting , such as garden lighting, landscape lighting , garden paths , or outdoor wall lighting . The lower voltage drop over longer cables is important in outdoor environments where lighting must be powered over significant distances.
  3. Commercial and Industrial Lighting :
    • In commercial environments where large lighting systems are used, such as shops , supermarkets , restaurant lighting , or showrooms , 24V lighting is useful because it helps to optimize light distribution while saving energy.
  4. Recessed Lighting and Spotlights :
    • 24V lighting is often used in recessed spotlights , built-in lighting, and spotlights . These systems are suitable for applications requiring precise light focus and a professional finish , such as office lighting or display lighting .
  5. Signage and Signaling :
    • Escape route and emergency lighting , route lighting and signalling systems can also benefit from 24V lighting because of its energy efficiency and easier integration into existing electrical systems.
  6. Interior lighting and mood lighting :
    • Indoors, 24V lighting is widely used for mood lighting in living rooms, kitchens, and bedrooms. The dimmability of LED bulbs with a 24V system provides pleasant and adaptable lighting for different needs.

Considerations when choosing 24V lighting:

  1. Inverter/Driver :
    • For 24V lighting, you need a 24V driver or transformer that converts the mains voltage (usually 230V) to 24V DC. Choosing the right driver is essential for the system's performance and longevity .
    • It is important to ensure that the driver delivers the correct current and power to the lighting so that the system works optimally.
  2. Installation complexity :
    • Installing a 24V system can be more complex than 12V systems, especially when covering long distances and requiring extensive wiring . Incorrect installation can lead to voltage drops or malfunctioning lighting.
  3. Cost price :
    • 24V lighting can be more expensive to purchase, both for the lighting itself and for the necessary drivers and accessories. However, the energy efficiency and long lifespan can justify the higher initial cost in the long run.
  4. Compatibility :
    • Make sure the 24V lighting you choose is compatible with the type of driver you're using. It's important that the lighting systems work well together to ensure maximum performance and safety.

Summary:

24V lighting offers significant advantages in energy efficiency , long cable runs, and better control over light distribution . It is ideal for larger lighting projects , outdoor lighting, and applications requiring better light uniformity . Choosing 24V lighting requires suitable drivers and careful installation, but the long-term benefits make it an attractive choice for both commercial and residential applications .
