Sundrax offers a full suite of devices, each engineered for specific areas — from technical rooms to mobile stage decor.

In lighting design, beautiful results depend on invisible infrastructure. Behind every stable ArtNet-controlled show or façade lies one critical component: the switch. A dedicated ArtNet switch is more than just a networking tool - it’s the backbone of your lighting data distribution.

While many installations begin with generic IT switches, large-scale or latency-sensitive lighting systems benefit enormously from equipment designed specifically for real-time control protocols like ArtNet and sACN.

In large-scale installations like architectural lighting, city infrastructure, or retrofits, running separate DMX signal lines is not always practical or cost-effective. That’s where DMX over power line technology offers a smart alternative – allowing you to transmit DMX512 control data using the same 110/220V power cables already in place.

This method is actively used by Sundrax in its PowerGate product line, delivering reliable, real-time control without extra cabling.

Lighting control in architectural and entertainment environments often involves two dominant but very different protocols: DMX512 and DALI. While DMX is preferred for dynamic, fast-changing effects, DALI excels in commercial and architectural settings where smooth dimming, status feedback, and group control are essential.

In modern architectural and stage lighting installations, where long-distance signal transmission and immunity to interference are critical, fiber-optic lines provide a powerful alternative to traditional copper-based DMX wiring. Sundrax offers dedicated solutions that enable stable and scalable DMX over fiber in real-world applications.

In the world of dynamic lighting design, nothing offers more visual impact than addressable pixel-based systems. From animated façades to immersive stage backdrops, the ability to control each pixel individually opens the door to stunning motion effects, gradients, and color sequences.

As modern lighting moves toward immersive visual design, addressable LED pixels have become essential for media façades, creative stage effects, and interactive installations. At the center of these systems is the ArtNet pixel controller – a device that receives network-based control data and distributes it precisely across thousands of individual LEDs.

With the increasing scale of lighting installations, the need for convenient management and diagnostics grows. This is where the RDM protocol comes to the rescue—a standard that enhances DMX with the capability of two-way communication. We discussed with an engineer from Sundrax Aleksandar Nikolic how RDM works and how it helps technicians save time during installation and maintenance.

When it comes to critical facilities—such as theaters, public buildings, tunnels, or architectural facades—a failure in the lighting control system can lead to serious consequences. We spoke with an engineer from Sundrax Alex Chomsky about how to properly implement emergency lighting scenarios based on DMX and what to consider for reliable operation in emergency situations.

In professional environments, DMX controllers are pivotal for managing lighting—whether for architectural illumination, theater stages, or urban landscapes. Their stability is critical, and the presence of a reset button on the controller’s casing may seem trivial but is, in fact, a warning sign of potential flaws in the device’s design.

DMX systems are widely used in stage lighting to control lighting devices with precision. However, when setting up these systems, mistakes are often made that can cause malfunctions or even equipment failure. In this article, we’ll explore the seven most common mistakes when connecting DMX systems and share practical tips on how to avoid them

Modern architectural and street lighting has evolved far beyond simple timer-based systems. Today, thanks to GSM and GPS technologies, it’s possible to not only control lighting remotely but also adapt it in real time to specific conditions, scenarios, and events. In this article, we’ll explore how this works in practice—using the example of the MONARQ system from Sundrax.

As the number of fixtures in DMX networks increases, the load on the line grows, raising the risk of failures and signal loss. Incorrect distribution can lead to erratic operation or complete equipment failure. We consulted with an engineer from Sundrax Alex Chomsky to learn how to properly design a DMX network for large-scale projects.

Architectural lighting is more than just illumination—it’s a powerful tool that brings buildings to life. Through color, brightness, contrast, and seamless transitions, it crafts mood, highlights intricate details, and accentuates form. At the heart of this expressive art lies dimming—not merely a way to adjust brightness but a method to transform the perception of color and the atmosphere of any space.

A correctly selected dimmer is the foundation of a stable and long-lasting lighting installation. We asked a Sundrax engineer Alex Chomsky to explain the difference between the main types of dimmers and how to choose the right one depending on the task.

In professional DMX installations, dozens or even hundreds of luminaires, controllers, splitters, and amplifiers are connected in a shared network through which the signal is transmitted. But what happens if a high-voltage surge ⚡️, for example, due to a short circuit, connection error, or even during a thunderstorm, enters one of the sections? Without galvanic isolation, such failures can damage or destroy all equipment across the network.

Digital control of architectural lighting is becoming an integral part of urban infrastructure. This article highlights the key technologies transforming the industry, according to Sundrax engineers. These are not mere predictions but specific directions already being implemented in modern projects.

Lighting today is far more than just lamps—it encompasses complex digital systems. To control lighting fixtures, various communication protocols are employed.
