Design and workmanship
The Lepro TB1 table lamp consists of three ring-shaped light elements arranged in a manner reminiscent of a gyroscope. The two inner rings are freely adjustable, allowing for flexible positioning of the light beam. Lepro primarily uses plastic for the lamp's construction, which, while not giving it a premium feel, is acceptable in this price range. The workmanship appears solid, the joints move smoothly, and the base ensures a secure hold on the desk.
The Lepro AI Neon LED Strip N1 is designed as a flexible light strip, available in lengths of 3, 6, or 10 meters. It consists of a soft silicone coating that protects the LED core and diffuses the light evenly. Visually, the N1 functions both as indirect lighting, for example behind furniture or along a wall edge, and as a direct light source.
The soft, flexible material makes it easy to shape the strip into even curves and forms. I spontaneously applied it along the wall and was immediately pleased with the result.
The included clips with adhesive pads can be used for mounting and hold securely. However, care should be taken when removing them, as the adhesive hardens slightly and can damage wallpaper. Alternatively, the brackets can also be screwed in place, which is recommended for permanent installations.
The power supply for the strip is connected separately; at the end there is a small control module with a switch and integrated microphone for music synchronization.
Setup and app
Both the Lepro TB1 and the AI Neon LED Strip N1 are set up via the Lepro Smart App, which is available for Android and iOS. After being switched on, the devices are automatically detected; they then only need to be connected to the 2,4 GHz Wi-Fi network. Both are ready for use within a few minutes.
The app allows you to adjust brightness, color temperature (between 2700 and 6500 K), and color modes. In addition to manual controls, there are numerous predefined scenes, such as reading, relaxing, party, or working. Changes are applied without any noticeable delay.
Furthermore, automation rules can be created so that, for example, the N1 LED strip automatically switches on as soon as the TB1 lamp is activated, or conversely, both devices react simultaneously when switched off. The connections work, but react with a slight delay of a few seconds because synchronization takes place via the cloud.
The key feature is the new AI engine LightGPM 2 (not to be confused with LightGBM!), which is used in both products. It is designed to automatically adjust the light to mood, time of day, and activity. Users can give simple text or voice commands, such as "I'm working," "I'm going to sleep," or "I want to game." The AI analyzes the input and creates a suitable light profile based on color, brightness, and dynamic range.
According to Lepro, LightGPM is based on a transformer-decoder architecture, similar to the large language models used by ChatGPT. Lepro's LightGPM, however, was trained with expertise in lighting design. The system can generate up to ten suitable suggestions from billions of possible combinations, which can then be manually adjusted or saved.
As long as familiar scene terminology was used, the AI worked quite well. The lighting suggestions seemed harmonious and practical, even though the AI is currently not capable of learning and doesn't take individual preferences into account. Nevertheless, it offers noticeable convenience, because instead of fiddling with sliders for different colors and effects, a short command is often enough to create the desired atmosphere.
For dynamic scenes, the LightBeats music mode is also available. Here, the TB1 and N1 react to music via their integrated microphones. The TB1 has a microphone in its base, while the N1 has a microphone in the control module at the end of the cable. Both pick up ambient sounds and synchronize the light animations to the beat. The response is precise and its sensitivity can be fine-tuned via the app.
Light quality
Both the Lepro TB1 and the AI Neon LED Strip N1 utilize RGBIC technology, which allows for the individual control of multiple LED segments. This enables the creation of complex color gradients and dynamic effects that go beyond simple RGB color changes.
The Lepro TB1 delivers a consistently bright light that can be dimmed continuously. In white light mode, it covers a wide range from neutral white to warm white, making it suitable for both working and atmospheric lighting. Colors are rendered vividly yet naturally, and transitions are seamless. Even at higher brightness levels, the light remains pleasant and glare-free.
In RGB scenes, the TB1 impresses with precise color transitions and smooth animations. Even with fast effects or color changes, it operates consistently and without visible flickering. The three light rings also create a spatial lighting effect, adding depth to the overall image.
The AI Neon LED Strip N1 also offers vibrant color reproduction and even illumination along its entire length. The silicone coating distributes the light homogeneously and prevents visible LED points. The strip creates a particularly impressive effect when used as a direct light source along walls or furniture edges.
The N1 performs somewhat weaker with dynamic effects. When a light pulse sweeps across the entire strip, the movement appears slightly jerky. While the speed can be adjusted in the app, the transition isn't entirely smooth. The TB1 reacts much more precisely here – color gradients and animations run more smoothly and naturally.
Smart home integration
Both devices can be fully integrated into the Lepro ecosystem and are centrally controlled via the Lepro Smart App. Additionally, the TB1 and N1 support the voice assistants Amazon Alexa and Google Assistant, allowing basic commands such as "turn on the light," "switch to relaxation mode," or "set brightness to 50 percent" to be executed by voice.
Advanced features such as the AI engine LightGPM or music control are only available within the Lepro app. Only standard commands can be used via Alexa or Google Assistant.
Lepro does not currently offer native support for Apple Home or Matter. However, a community integration for Home Assistant exists via the Home Assistant Marketplace, enabling basic control functions. This integration does not officially use a local API, but instead accesses the Lepro app's cloud interface; however, it worked reliably in testing.
