Smart, Sustainable Lighting Solutions
Lighting efficiency with ‘Wow’ factor
Smart lighting control isn’t just about convenience, it’s a key driver in reducing energy consumption and cutting carbon emissions across public, commercial and residential buildings. At Theben, we offer a reliable and cost-effective range of solutions designed to deliver just that.
Whether you’re upgrading an existing system or starting from scratch, our dimmer switches, digital and astronomical time switches, staircase timers and electro-mechanical relays help ensure lighting is used exactly when and where it’s needed, no more, no less. These solutions are ideal for municipal buildings, schools, car parks, stairwells, commercial units and more.
And while our technologies are innovative, our philosophy is simple: build quality that lasts. That’s why we test our lighting control products to standards far beyond the industry minimum – 40,000 switching cycles, maximum load – to deliver the performance and peace of mind you expect from Theben.
Need flexible, dependable lighting control without the cost or complexity of a full automation system? Start here. Each product on this page has been engineered for fast installation, intuitive use and long-term reliability, because saving energy shouldn’t come at the expense of time or budget.
Dimmer Switches
Exactly what LEDs need.
Theben offers LED-compatible dimmer solutions designed to switch and dim safely, reliably, and efficiently – even with the unique demands of modern lighting.
While LED technology has transformed the lighting industry with better efficiency and colour rendering, it also presents new challenges for control systems. Retrofitting LEDs into traditional installations can sometimes lead to faults, flickering or damaged components due to extremely high inrush currents, often hundreds or even thousands of times above the rated load.
That’s where Theben dimmers come in. Engineered specifically to handle the complexities of LED lighting, they protect against contact damage and ensure smooth, flicker-free dimming performance. Whether you’re working with retrofit lamps, LED strips, or high-performance fixtures, Theben gives you the confidence that your lighting control system is up to the task, now and in the future.
Digital Time Switches
Precise control. Maximum efficiency.
Theben’s digital time switches offer flexible, programmable control for lighting and other loads – from electric heaters and pumps to school bells, barriers and signage. Mounted on DIN rails, they’re ideal for public buildings, schools, commercial premises and more. With 10-year power reserve, Bluetooth connectivity via the OBELISK top3 app, and tamper protection, these time switches offer dependable performance where it matters most.
Astronomical Time Switches
Lighting that follows the sun.
Our astronomical time switches automatically adjust to the sunrise and sunset times of their installed location – no sensors required. Perfect for outdoor lighting, signage, shop windows, and greenhouses, they ensure lights switch on and off only when needed, optimising energy use across the seasons. A smart, sustainable solution with built-in reliability.
Staircase Time Switches
The original. Still the benchmark.
Theben’s ELPA staircase timers have been setting the standard for almost a century. The latest ELPA 6 plus offers ten easy-to-set functions, robust build quality, and the trusted “fit and forget” performance Theben is known for. Thanks to a universal connection layout, replacing existing timers with ELPA is quick and simple – no rewiring required.
Electro-Mechanical Latching Relays
Robust switching for high-load demands.
Designed for long service life and minimal maintenance, Theben’s electro-mechanical latching relays are built to withstand repeated switching under high loads. Perfect for corridor, stairwell or commercial lighting systems, they combine simplicity and strength, with the reassurance of Theben build quality.
