3LR Lighting is built on the principle that lighting is more than just a visual element — it’s an emotional force. The company’s founder, Matt Lloyd, has dedicated his career to harnessing this idea, and 3LR’s mission today remains rooted in the belief that lighting should be designed not just to illuminate, but to resonate.
At its core, 3LR believes lighting is the “magic dust” within a space — capable of enhancing atmosphere, guiding emotional response, and completely transforming how people feel. That’s why, in every project, the company begins by encouraging clients to think not just about what a space looks like, but about how they want people to feel the moment they enter.
This emotional approach is what defines 3LR’s philosophy of “Lighting by Emotion.” Whether working in theatres, cruise ships, restaurants, or private residences, the team designs lighting systems that are both technically precise and emotionally powerful. Every installation is treated as an opportunity to create a sensory experience — from the warmth of a family kitchen to the grandeur of a concert hall.
The company’s name, 3LR, refers to the third light receptor in the human eye — a little-known but vitally important discovery in visual science. While rods and cones enable us to see, scientists uncovered a third photosensitive cell in the eye responsible for regulating our circadian rhythm — the body’s internal clock that governs sleep, alertness, and overall emotional balance. This third receptor responds to changes in light, influencing not what we see, but how we feel. It’s this insight that continues to guide 3LR’s work, helping the company design lighting that connects on a deeper, human level.
Understanding the nuances of light — such as how colour temperature and spectrum influence mood and wellbeing — allows 3LR to specify technologies that make emotional and biological sense. In a time when LED technology dominates the industry, many users miss the emotional warmth and natural feel of tungsten. 3LR addresses this by working with trusted manufacturers to supply LED solutions that maintain emotional authenticity while meeting modern efficiency and control requirements.
This careful approach is evident across 3LR’s extensive project list, which includes work at high-profile cultural venues such as the Royal Albert Hall, National Theatre, Sadler’s Wells, Glyndebourne Opera House, Bristol Beacon, Liverpool Everyman, Birmingham Hippodrome, and @sohoplace. These venues understand that lighting is no longer just about visibility — it’s about atmosphere, memory, and impact.
One notable example is the refurbishment of the Whyte Recital Hall at the Royal Irish Academy of Music, where lead architect John Palmer of TODD Architects praised 3LR’s lighting work for setting a powerful emotional tone before a performance even begins.
But 3LR’s work extends far beyond performance spaces. The company regularly works in hospitality, residential, and commercial environments, creating immersive experiences that enrich everyday life. A recent residential project involved a lighting redesign for a large kitchen-diner. Initially surprised by the detail and intent behind 3LR’s proposal, the client later described the outcome as transformative, stating they wished they had extended the approach to the entire home.
At every scale and in every sector, 3LR’s work is grounded in understanding people — their habits, their emotions, and their expectations of a space. This is what drives the company’s passion and informs its partnerships with leading international lighting and control equipment manufacturers.
Ultimately, 3LR exists to help clients connect people with place through the thoughtful, emotional, and scientific use of light. The company continues to push boundaries in lighting design — not by chasing trends, but by honouring the deep human connection between light and emotion.
