Stair Lights

LED Stair Lights - What Is Included?

Stair lights are LED lighting bars installed beneath each stair riser or along the edge of the staircase to illuminate individual steps. By lighting every tread, they improve visibility in low-light conditions and help reduce the risk of missed footing or trips when moving up or down the stairs.

In addition to safety, stair lighting also contributes to the aesthetic. When installed correctly, each step becomes subtly highlighted, creating a structured lighting effect that enhances the staircase without overwhelming the surrounding room.

The stair lights in this category use 24V DC LED bars designed for indoor residential installations. They are available in 500mm and 1000mm lengths, which suit the majority of UK staircase widths. The bars can be installed individually along each step and connected together through a structured wiring system.

These LED stair lights are also designed for smart control. The system connects to the Tuya platform, allowing the lights to be paired with the Tuya or Smart Life mobile app. Through the app, users can adjust colour temperature from warm white to cool white, control brightness levels, and configure motion-trigger behaviour.

For homeowners planning a staircase upgrade, stair lights offer a clean and structured lighting solution that integrates directly into the staircase itself.

Motion Sensor Stair Lights - How the System Works

The stair lighting system is designed to be straightforward to understand and practical to install. Each component works together to create a coordinated lighting effect that activates automatically when someone approaches the staircase.

Daisy-Chain Wiring System

Each LED bar connects to a T-junction connector. A single cable runs up the staircase with each bar plugging into the junction points. Instead of separate wiring for every light, every step simply taps into the same cable run, making the layout easier to plan and install.

This daisy-chain approach keeps the installation organised and reduces wiring complexity. 

Motion Sensor Activation

The system includes two PIR motion sensors, positioned at the top and bottom of the staircase. These sensors detect movement when someone approaches the stairs and trigger the lighting sequence.

Sequential Step-By-Step Lighting

Instead of turning on all the lights at once, the system activates the LED bars in a step-by-step sequence. Each step illuminates shortly after the previous one, creating a flowing lighting effect along the staircase.

The delay between each step can be adjusted in the Tuya or Smart Life app. For example, users can set a short delay for faster illumination or a longer delay for a slower lighting progression.

Low-Voltage 24V Operation

All LED bars operate on 24V DC low voltage, supplied by a compatible 24V LED driver (sold separately on site). The driver converts the mains power to the required voltage for the lighting system. Low-voltage operation means the light bars themselves are safe to handle during installation and suitable for residential DIY projects.

The 24V driver connects to the mains circuit, which may need a qualified electrician’s help, especially for inexperienced installers.

App Control via Tuya / Smart Life

The stair lighting system integrates with the Tuya platform, allowing users to control the lights through the Tuya or Smart Life mobile app.

Within the app, users can:

• Adjust colour temperature from warm white to cool white
• Control brightness levels
• Configure motion trigger timing and sequence speed

This level of control allows homeowners to customise how their motion sensor stair lights behave depending on their preferences.

Choosing the Right Stair Light Bar Size

Selecting the correct bar size is one of the most common questions when planning stair lighting. Fortunately, the system is designed to accommodate a range of staircase widths, including layouts where a continuous lighting effect is preferred.

Most residential staircases in the UK have step widths between 800mm and 1000mm. The available LED bars are designed with these typical measurements in mind.

500mm Stair Light Bars

The 500mm bar is often chosen for narrower staircases or for installations where a shorter light bar is preferred visually. This size works well, similar to how installing LED strip lights for stairs creates a more subtle lighting line beneath each step.

1000mm Stair Light Bars

The 1000mm bar is designed for wider staircases or for installations where full-width illumination across each step is preferred. This makes it a strong lighting for stairs option where more consistent coverage is required.

Cuttable Bars for Custom Lengths

Both bar sizes are cuttable, allowing them to be trimmed to suit the exact width of a step if required. The process is straightforward:

1. Measure the required length.
2. Cut the bar using a saw.
3. Reconnect the plug-in connector.

No soldering is required. Once the connector is reattached, the bar can be installed into the system.

This flexibility makes the LED bars suitable for a wide range of stair designs, including installations where the step width does not match the standard bar length exactly.

Complete Stair Light Kits

For convenience, kits are available as well. These kits include the LED bars along with the sensors and controller needed for the system. Product selection is simplified by providing the main components required to create a working stair lighting setup.

Key Features at a Glance

Each system includes two PIR motion sensors, positioned at the top and bottom of the staircase to detect movement and trigger the lighting sequence automatically. The lights activate in a sequential step-by-step pattern, with each step illuminating after the previous one to create a smooth, flowing effect along the stairs.

Through the Tuya / Smart Life app, the system offers full control over how the lighting behaves. Colour temperature can be adjusted from warm white to cool white, brightness levels can be increased or dimmed, and the delay timing between each step can be programmed to suit the desired speed of illumination.

Installing Your Stair Lights — What to Expect

The system is designed so that the LED bars and wiring can be installed by a competent DIYer. The stair lights operate on 24V DC, which means the light bars are safe to handle during installation.

The 24V driver, however, connects to the mains supply. Depending on how the driver is wired into your home’s electrical system, the mains connection may require a qualified electrician.

Proper installation ensures compliance and safe integration into the household wiring.

Typical Installation Process

Installing indoor lighting for stairs generally follows a straightforward process:

1. Measure and mark each step to determine where the bars will sit.
2. Cut the bars to size if necessary using a saw.
3. Attach the mounting brackets beneath the stair riser, just under the nosing, or on the wall if stair wall lights are preferred.
4. Clip the LED bars into place.
5. Run the T-junction cable up the staircase to link each light.
6. Install the PIR sensors at the top and bottom to enable motion sensor lights for stairs.
7. Connect the system to the 24V driver.
8. Pair the system with the Tuya / Smart Life app.

Once configured, the lights will activate automatically when movement is detected on the stairs.

Because the system uses structured wiring and plug-in connectors, installation remains manageable for homeowners
