Light is not a decoration, it is a biological signal that shapes how we feel, think and function.

Based in the UK, 3LR delivers visually-striking, state-of-the-art and sustainable lighting solutions, drawing on over a hundred years’ experience and our in-house expertise to create, design, specify and deliver bespoke lighting concepts.

Today 3LR offers two different distinct lighting solutions,
that work hand in hand or independently.

We specialise in professional services and project work, drawing on over a hundred years’ experience and our in-house expertise to create, design, specify and deliver bespoke lighting concepts.

As a company, we were founded with the mantra of ‘Lighting by Emotion’ and this lies at the heart of everything we do. Whilst lighting can be used to transform a space, it’s been scientifically proven that it actually generates an emotional response from a person. This occurs through the third light receptor in our eyes, hence our name 3LR…

Professional Services

Lighting and its emotional resonance has the power to transform any environment, which is why our work spans such diverse sectors.

From traditional theatres and heritage buildings to maritime projects and residential properties, we apply our expertise to help every client experience the full impact of light.

Projects by design

We offer a full turn-key service and support clients all the way from an initial conversation about a lighting scheme through to the complete delivery and installation of whole project.

An example of our services includes project management, specialist consultancy, system control design, lighting design, cost planning and budget and DiaLUX Design, to name but a few.

Why 3LR

Our mantra is ‘Lighting by Emotion’.
This means we use light to create emotional connections within a space – providing our clients and their venues with a truly unique experience.

This is also why we are named 3LR after the eye’s third light receptor, which governs how we as humans emotionally engage with light.

3LR provided expert consultancy as we were planning the Royal Ballet and Opera House’s once-in-a-generation production lighting LED upgrade. Their engagement with the stakeholders was thorough and knowledgeable, assessing governance, methodology, delivery, costs, and risk management. Their support of the business case was critically important to us as trusted colleagues in the industry, and their comprehensive understanding of the full range of the project made for a meaningful and valuable contribution.

'During the recent lighting upgrade at the Royal Festival Hall, 3LR went above and beyond in helping us deliver what was a truly ambitious project. Their input was paramount at every stage and they were constantly coming up with solutions when there didn’t seem to be any! Everyone at the Southbank Centre is incredibly grateful for their insight, professional and passion for lighting.' Roger Hennigan, Technical Manager, Southbank Centre
