FUTURE OF LIGHTING INNOVATION SPECIAL
Te rapid rise of LEDs shows how quickly the lighting industry can be transformed. Jim Dawson, of SG Lighting, predicts the next revolution to sweep the market
he lighting industry could be on the brink of a smart tech revolution, which will boost workers’ wellbeing and improve productivity at the flick of a switch. Biodynamic solutions
that work in harmony with human body clocks are forecast to be at the forefront of future innovation. They involve tunable white lighting, which uses a range of adjustable colour temperatures that replicate outdoor conditions and have been shown to have an effect on people’s emotions. And their rise could be as rapid as the sudden surge in LEDs seen in recent years – transforming how we illuminate offices, factories, schools and hospitals.
Proving the benefits Jim Dawson, Technical Manager at SG Lighting Ltd, predicted: “The next thing that is going to revolutionise the lighting industry will be 100% tunable white lighting.
“The human body has evolved over
thousands of years to take our body clock cues from the sun.
“Biodynamic lighting is about giving back what we’ve lost by moving into these artificially lit caves we call homes

and offices. We’re able to do this with a lighting system that is able to emulate the changing colour temperatures and changing intensity of outdoor lighting.” Jim believes the rise in popularity of tunable white lighting is being driven by two factors – a cut in costs and research backing its benefits. He said: “The cost has come down
hugely. It used to only be in higher end ranges but now we have solutions which cost slightly less than the old fluorescent lighting. It’s very affordable now. “The other factor is that research has been done showing the significant difference it can make. Biodynamic lighting has been around for a while but it was very difficult to get anyone to put solid figures to it. A test was done on a production line and there was a five to seven per cent increase in productivity. In a call centre it cut
sickness by two per cent. That’s a massive amount of money to save.”
Simple solutions Jim highlighted two main ways tunable white lighting is used.
He explained: “There’s a basic version – a teacher
who wants kids to be alert in the morning can set it to a colder colour, like 6500K. At lunch you might go to 3000K to make it more relaxed. “Then the gold standard is a true biodynamic 24-hour system. You link it to a 24-hour clock and it cycles on whatever rhythm you’ve chosen. It’s so smooth you’d never know the light was changing. Those systems have been expensive in the past. But we’ve brought in our own app control and it’s
“We have solutions which cost slightly less than the old fluorescent lighting, it’s become very affordable now”
