About Lorraine Calcott IEng FILP IALD CLD MSLL MCIBSE BSS – Director and Principal Designer

As the Director and Principal Designer at it does Lighting Ltd., I bring nearly 40 years of experience and a genuine passion for lighting design to every project. I’ve dedicated my career to understanding how light influences health and well-being, which is also the focus of my ongoing PhD research. Since founding the company in 2004, I’ve been fortunate to drive meaningful change within the lighting industry while building a thriving practice that prioritises creativity, expertise, and a person-centred approach.

I’m honoured to hold numerous professional qualifications, including Fellowship of the Institution of Lighting Professionals (FILP), Incorporated Engineer (IEng) grade, and Certified Lighting Designer accreditation (CLD) through the IALD—one of only 74 individuals worldwide to achieve this distinction. I’ve also co-authored industry-leading guidance documents, such as the lighting and crime standards for Secured by Design (SBD), and I contribute to several committees within the International Association of Lighting Designers (IALD) to help shape the global direction of our profession.

Education is a vital part of my journey, and I remain committed to lifelong learning, completing over 100 hours of CPD annually. I actively share my knowledge by delivering training to professionals across industries, as well as to those outside the lighting sector.

My passion extends to designing spectrally specific artificial lighting that supports health and well-being. I collaborate with industry leaders and universities to develop solutions for individuals facing challenges such as mental health issues, dementia, and Alzheimer’s. I am also engaged in cutting-edge research with University College London (UCL), exploring the impact of infrared light on mitochondrial health. This research has inspired the development of a product designed to counteract the negative effects of blue light emitted by LED sources—a key milestone in my mission to promote healthier lighting solutions.

For me, lighting is far more than just design; it is an essential tool for improving lives. Whether addressing sleep disorders, eye health, or creating supportive environments for hospitals, care homes, and end-of-life care, I relish the opportunity to advise on how light can positively influence biological rhythms and overall well-being. With over 90% of people in the UK spending less than 30 minutes outdoors each day, I believe this is one of the greatest health challenges our society faces.

At it does Lighting Ltd., I incorporate this ethos into every aspect of my work, from street lighting and ecology-sensitive designs to transformative lighting solutions for human health. Thoughtful design is at the heart of everything I do because light—both natural and artificial—plays a crucial role in our lives.

If you’re seeking lighting design services, consultancy, training, or advice, I’d love to help. Let’s work together to bring your ideas to light.
