How To Install Led Strip Lights On Stairs

15 1

Today, we are going to share some led lighting solutions about how to install LED stair lighting, please read on if you are interested.

Prepare Materials

Before you start the installation, you need to prepare the following materials:

  • LED strips: I usually choose led strip lightswith 3M adhesive stickers because they are easier to install and can be easily replaced when needed.
  • Power supply: Depending on the type of LED strip used, a 12V or 24V power supply is required. Make sure the power supply can meet the power requirements of the strip being used.
  • Connector: Use the connector to connect the LED strip to the power supply and the controller.
  • Controller (optional): If you want to control the brightness, color and blinking mode of the light bar, you can choose to use a controller. Some controllers also have an auto-off feature that automatically turns off the light bar for a specific period of time to save energy.
  • Tools: Basic tools such as scissors, sharp pliers and measuring tape.

Step 1: Measure the length of the stairs

First, use a measuring tape to measure the length of your stairs. Use the measurement to figure out how long you need the LED strip. I usually choose to buy more lengths so that I can cut the strips if needed. Also, if your staircase has curved sections, you will need to use bendable LED strips.

Step 2: Prepare the light bar and power supply

Next, use scissors to cut the LED strips to the proper length and use sharp nose pliers to connect the connectors to the LED strips and power supply. Make sure to connect the correct polarity.

I recommend adding some heat shrink tubing between the connector and the LED strip to strengthen the connection to ensure a solid connection.

Step 3: Install the LED strip

Now, attach the LED strip to the staircase. Using 3M adhesive sticker can make the installation easier. For curved stairs, you can bend the light bar to the desired shape. Attach the light bar along the side of the staircase.

I recommend cleaning the stair surface and using some alcohol or other cleaner to remove grease and dirt from the surface before attaching the light bar to ensure that the light bar can be firmly attached.

Step 4: Connect the controller

If you choose to use a controller, you will need to connect the controller to the LED strip. The connector connects the controller to the LED strip and the power supply. If you are not using a controller, simply connect the LED strip to the power supply.

Before connecting the controller, make sure you have tested the strips and that they work properly.

Step 5: Test

After completing the installation, test the LED strips to see if they are working properly. You can use the controller to test the different brightnesses, colors and blinking patterns of the strips. If you are not using a controller, you can simply test the light bar to see if it lights up properly. If you find any problems, please recheck the connectors and polarity and make sure the power supply meets the requirements.

Safety Precautions

When installing LED stair lighting, be sure to observe the following safety precautions:

  1. Turn off the power to all relevant circuits to avoid the risk of electric shock.
  2. Use insulated tools and wear personal protective equipment such as insulated gloves and safety glasses.
  3. Make sure the stair surface is dry and free of grease and dirt before installing the light bar.
  4. During installation, do not over-bend the light bar to avoid damaging the light beads or connectors.

The above is the entire process of how to install the light in the stairs, for more installation tutorials, please consult custom led light manufacturers


  1. How do you light up stairs?

Create light from above with pendant lighting, which can provide ambient light for the area, or use recessed ceiling lights in a flat ceiling to cast light downwards. Meanwhile, wall-recessed stair lights can illuminate the treads effectively, and wall lights can be an elegant addition.

  1. Do I need an electrician to install LED strip lights?

One of the best things about LED strip lighting is that you do not have to be an electrician to install them. You can find starter kits that will provide you with everything you need to make the process as easy as possible.

  1. Can LED lights stick to concrete?

To mount the LEDs, apply a strip of a bonding agent, such as Liquid Nails Heavy Duty, to the surface of the concrete. Make sure the line of bonding agent is thick enough to create a smooth, flat surface for applying the LED strip.

  1. How do you hang lights on concrete without drilling?

Another option to hang lights on a concrete wall is to use command strips. We’ve talked about these before in our how to hang LED strip lights here. Command strips are a type of adhesive strip that can be attached to the wall, which you then attach another command strip to, which you attach your wall feature to.

  1. Where do you put lights on stairs?

Recessed and mounted spots are popular stair lighting choices, usually installed between 15 and 20cm above the steps. Not only do they look incredibly flush and subtle, but they provide adequate low-level lighting for your stairs and can create stunning effects too.

  1. Which light is good for stairs?

Recessed lights have multiple uses. When placed correctly, these lights can bring the stairs alive and enhance your home interiors. You could use spotlights or wall mounted recessed lights and space them out evenly to illuminate the stairs with a warm and soft glow.

  1. How do you light concrete stairs?

A great solution is to install lighting into the vertical part of a stair, called the riser. Concrete step lights, or tread lights, fit right into the stairs and focus light downward onto the step immediately below it. They offer enough light for safety, but the light is subtle enough that it isn’t distracting.

  1. Is it cheaper to run LED strip lights?

Yes. LED strip lights are incredibly cheap to run. This is because LED converts 90% of its energy into light, making it the most cost-effective light source around.

  1. Can LED strip lights go out?

LED strip lifetime is not just about the LEDs!

Although LED longevity is the most discussed aspect of LED strip lifetime, it is actually the adhesive and power supply that are just as likely to fail, and when they do, fail catastrophically.

  1. Can LED light strips be thrown away?

LEDs are energy-efficient and eco-friendly too. With these characteristics, LED products are not toxic and can be recycled.
