The Ultimate Guide to Installing LED Strip Christmas Lights​

In this comprehensive guide, we will walk you through everything you need to know about setting up permanent LED strip Christmas lights. Whether you’re a seasoned pro or a beginner, this guide will provide you with valuable insights and tips to make your installation a success.

1. LED Strips or LED Strings: Which One is Better?​

Let’s begin with the fundamental question: should you choose best led light strips or LED strings for your installation? Both options have their advantages and considerations.

LED strips offer a clean and sleek look when installed in aluminum channels with white diffusers. On the other hand, LED strings can be mounted in drilled-out J-channels or purpose-built mounting solutions. The choice between the two ultimately comes down to aesthetics and personal preference.

If you want your LEDs to point towards the road and be completely concealed, LED strips are a great choice. On the other hand, if you prefer a more indirect lighting effect, LED strings will work just fine.

LED density is typically higher in LED strips, resulting in smoother animations when viewed head-on. However, the difference is less noticeable when your LEDs are directed towards the house.

Durability-wise, both pixel strings and strips are equally reliable once permanently installed. However, if you plan on taking your LEDs up and down or moving them around, pixel strings are a more suitable option since they are less delicate.

When it comes to fixing a faulty LED, pixel strings are easier to repair since you can simply cut out the affected pixels. Strips, on the other hand, require more intricate repairs.

Consider these factors and choose the option that best suits your preferences and installation requirements.

2. 5V or 12V Voltage: Which Should You Choose?​

The voltage you choose for your LED lights is an important consideration. In simple terms, voltage determines the intensity of the electrical current flowing through the wires.

Using 12 volts requires less power injection and allows for pushing more electrons through smaller wire sizes. However, it comes with a safety tradeoff.

While it is extremely difficult to cause an electrical fire with 5V LEDs, 12V systems have the potential to generate enough heat to melt and smoke the plastic. If safety is a concern, 5V LEDs are generally safer.

Consider your specific needs and assess the potential risks before making a decision.

3. Choosing the Right Type of Pixels: WS2811, WS2812, WS2815​

If you decide to go with LED strings, the most common choice is WS2811 pixels, available in both 5V and 12V variants. LED strips offer a bit more flexibility in terms of pixel variety.

The most popular and readily available 5V LED strips are WS2812B strips. For 12V strips, WS2815 is the recommended option, although they are slightly pricier compared to WS2812B.

There are also 12V strips with WS2811 chips available at a lower price. However, keep in mind that these strips can only be controlled in banks of 3 LEDs, limiting the versatility for direct lighting applications.

Additionally, you may consider RGBW strips, which have a dedicated white LED. These are ideal for year-round ambient lighting, but they may require more maintenance if used frequently.

Pay attention to the specific requirements of your installation and choose the pixel type that best aligns with your needs.

4. Selecting the Right Power Supply​

Choosing the right power supply is crucial for ensuring optimal performance and longevity of your LED lights. A general rule of thumb is to budget around 50 milliamps (or 0.05 amps) per 5V LED or 30 milliamps (or 0.03 amps) per 12V LED.

For example, a 5V 50A power supply should be sufficient to drive 1000 LEDs, while a 12V 30A supply can handle 1000 12V LEDs.

It’s important to note that these estimates account for safety and efficiency. While your LEDs may not actually pull the maximum estimated current, it’s always recommended to avoid running a power supply at its maximum capacity for sustained periods.

MeanWell is a well-regarded brand for power supplies, but economical generic power supplies can also be reliable, as long as they meet the required specifications.

Additionally, use 18 gauge 3-core wire for optimal wiring and consider using RVV wire with a thick PVC jacket for increased durability.

Ensuring proper power supply selection and wiring will prevent voltage drops and other electrical issues.

5. Wiring and Joining Strips or Strings​

Properly joining and wiring your LED lights is crucial for a seamless installation. Let’s explore the best practices for each type.

If you’re using pixel strings, they usually come with connectors on the ends for easy attachment. However, these connectors are not waterproof, so for permanent installations, it’s recommended to replace them with waterproof options such as solder seal butt connectors.

To join led strips BLLS , a more involved process is required. It’s recommended to pre-measure the exact length of strip needed for each section of your roof. This way, you can avoid any cutting or soldering on a ladder.

To join two IP65 waterproof strips together, carefully peel back the silicone covering from one end. Use a pair of nippers to cut into the covering without damaging the strip. Sacrifice one pixel to have a complete pad for soldering.

Apply heat shrink tubing over one side of the strip, and attach the full pad to a heat-resistant surface. Place the half pad on top and solder each pad junction. Fill the exposed area with hot glue and slide the heat shrink tubing over it. Applying heat will melt the glue and seal the connection.

When going around corners or making angles, bend the strip from front to back, avoiding side-to-side bending. Cut the strip and remove the silicone covering before soldering wires onto the pads.



Adding power injection points is essential to maintain consistent voltage along long installations. It’s recommended to add these points at corners or junctions. Cut into the silicone covering, add a bead of solder to the positive voltage and ground pads, and attach 18 gauge copper wire. Seal the connection with hot glue and heat shrink tubing.

By following these steps, you can ensure secure and reliable wiring for your LED lights.

6. Power Injection​

Power injection is necessary when powering long strings of LEDs from a single location. As you move further down the strip, the voltage available to each LED decreases due to the limitations of the tiny copper traces within the strip.

For 5V strips, it’s generally recommended to inject power at the beginning and end of every 5-meter section. For 12V strips, power injection should be done at the beginning and end of every two strips, or approximately 10 meters.

The most effective power injection technique is called home run injection. This involves running a separate power wire from the power supply to each injection point. It ensures consistent voltage throughout the installation.

If home run injection is not feasible, parallel injection can be used inside the strip. By adding parallel wires, the current-carrying capacity is increased, reducing the voltage drop along the strip.

Implementing proper power injection techniques will prevent color inaccuracies and ensure consistent lighting performance.

7. LED Controller Hardware: Enter WLED​

The LED lighting hobby used to be divided between those who sequenced full-out shows and those who preferred low-key setups. However, with the development of WLED, the line between the two has blurred.

WLED is a powerful LED controller software that has revolutionized the industry. It can be seamlessly integrated with various hardware options, providing flexibility and convenience.
