HDMI 2.0 4K*2K Sync Junction Box for Real-Time Computer and TV RGB Lighting Control

This GL-SN-002K model junction box serves as the central control unit for creating synchronised ambient lighting that reacts to your video content. By connecting via the supplied HDMI 2.0 4K*2K cable, it takes the colour and motion data from your PC monitor, television, or gaming console and translates it into commands for an attached RGB LED light strip. The package includes the necessary 5V 1A power cord for the box itself and a short 0.3m HDMI cable, allowing for a quick start. It's important for users to note that this setup requires a separate, compatible 2-metre RGB LED strip and its corresponding power supply, which are not part of this package. The system is designed for indoor use where immersive lighting can enhance viewing, gaming, or creative work.

Features and Construction

The core function of this product is to enable video synchronisation for RGB lighting. Its construction is centred around a compact junction box that processes the HDMI signal.

Material and Build

The junction box and included cables are constructed from standard electronic components and plastics typical for this category of device. The build is focused on functionality, with ports for HDMI input, DC power input for the box, and output for the LED strip. The IP20 protection rating indicates it is protected against touch by fingers and objects larger than 12.5mm, and offers no protection against water, making it suitable for dry, indoor environments away from moisture.

Size and Practical Fit

The main junction box has a footprint of 160mm in length, 90mm in width, and a profile of 20mm in height. This compact size allows it to be discreetly placed near your entertainment setup or computer desk. The included 0.3-metre HDMI cable is designed for short-distance connections, ideal for directly linking a device to the box placed immediately beside it. The system supports the synchronisation of lighting for a 2-metre long RGB LED strip, providing a substantial run of light for behind a monitor or television.

Uses and Placement

This sync box turns standard RGB lighting into a dynamic component of your screen-based activities, suitable for both dedicated setups and general enhancement.

Event or Professional Use

For content creators, streamers, or presentations, the synchronised lighting can extend the visual atmosphere of the screen into the physical space, making for a more engaging viewer experience. The real-time colour matching means the room's lighting can accentuate scene changes, game events, or visual themes without manual adjustment. Its compatibility with 4K*2K HDMI 2.0 sources ensures it works with modern high-resolution video output.

Everyday Home Use

In a living room or home theatre, the box can drive lighting behind a TV to reduce eye strain and increase immersion during movies or sports. For PC gamers, it adds a layer of environmental feedback, where explosions, health status, or in-game environments are reflected in the room's lighting. The specified operating temperature range of -20°C to 60°C covers typical indoor home environments.

Benefits and Buying Value

The value lies in transforming static backlighting into an interactive feature, using the provided core components to establish the system.

Reuse and Low Maintenance

The junction box is a durable control unit that can be used repeatedly with compatible 2m RGB LED strips. Maintenance is minimal, primarily involving ensuring clean connections and operating within the stated temperature parameters. The IP20 rating means it should be kept in a clean, dry location to prevent dust accumulation from interfering with ports.

Why Choose This Product

This product provides a straightforward path to video-synced lighting by including the essential control box, its power supply, and a connecting HDMI cable. The clear specification of a 2-metre strip length, DC 12V input, and compact 160x90x20mm box dimensions allows for accurate planning of your setup. It offers a specific solution for users who want lighting that actively responds to HDMI video content rather than operating on a separate, static cycle.
