4 December 2025

Episode S5E12

Lighting is a integral part of designing any interior space, but it takes on added significance in situations where older people may not go out as often as they might have when they were younger. In this episode, Kam Dhatt, an international expert in circadian lighting, joins Lori for a discussion that touches on his research into chronobiology and the neuroscience of light. Even if you think you understand the science behind circadian lighting, we promise you: there’s a lot here you will never before have considered!

This month’s Innovation Spotlight shines this month on Inclusive Design products from the German manufacturer HEWI for bath and shower rooms.  

About Kam Dhatt

Kam Dhatt is a lighting design expert and entrepreneur whose passion for the impact of light truly took off during a transformative experience in Australia. Although he began his career in the UK, working for major lighting manufacturers like Concord Lighting and Sylvania Lighting, it was the stark contrast he observed in Australia’s natural daylight that made him realize how lighting influences what he calls the “smile factor” and overall well-being. 

As a technical, geek-minded individual, Kam saw the potential of LED technologies to replicate the qualities of natural daylight indoors. His work with innovative products like Coelux has showcased how we can bring the benefits of natural light into built environments. 

Kam’s journey into chronobiology and the neuroscience of light became more personal following his ADHD diagnosis, which fuelled his curiosity about how light influences the brain and behaviour. Being married to an optometrist gave him deeper insights into the intersection of vision science and lighting. Recently, he’s been exploring red light photobiology, cellular health, and how lighting can enhance sleep and well-being. 

In essence, from his early days with Concord and Sylvania to co-founding Kazzar Lighting & Controls, Kam blends a rich professional background with a unique perspective on how lighting can truly transform our environments and well-being.
