Human-centric lighting represents a new way of using light in our lives, but there is some skepticism over its use and its effectiveness. Do we know enough about the technology, for example, to be using it in schools? Is there enough evidence to say that human centric lighting improves productivity at work? Can HCL help to maintain a smooth circadian rhythm at home?
In a 'Clash of the Lighting Titans' Lux's applications editor John Bullock (a HCL cheerleader) and our technical editor Alan Tulla (a sympathetic skeptic) sit down to compare and contrast their human centric lighting opinions.
Lighting professionals: What you see may upset you. Ray Molony counts down Lighting Spy’s Top 40 worst crimes, blunders and screw-ups.
We bench test and rate the latest products from the major brands. Report by Lux technical editor Alan Tulla.
Everyone’s talking about circadian rhythms, but how much do we really know about this intimate relationship that we have with the world in which we live?
It’s back to school for our resident boffin this month, as we cast a designer’s eye over classroom lighting
Human-centric lighting has been the buzz-phrase of the past couple of years. It has its basis in sound scientific research, but what does that research actually say? Prof. Christian Cajochen of University of Basel blows away the marketing fog and explains what’s really going on.
