What Makes Us Different
We’re independent..
We’re independent, qualified, and evidence-led. Our work draws on nearly four decades of professional lighting experience, continuing research, and active involvement in industry standards and professional committees.
We see what others miss..
We look beyond lumens and lux. Our evidence-led approach considers visual performance, comfort, timing, spectral characteristics, energy, ecology, and the people and animals affected by light. We distinguish established guidance from emerging research and translate both into responsible, practical recommendations.
We speak lighting and planning..
“We speak lighting and planning, health, ecology, design, and compliance fluently.” Use us early to reduce issues later on, its never too early for a lighting designer to be involved.
If you want more than light fittings on a drawing..
“If you want more than light fittings on a drawing, you’re in the right place.” Our designs are fully integrated with other disaplines and shape the evolution of your project from the start. We don’t just produce a layout, we produce a fully thought through design.
