Taking the health effects of lighting seriously is on the minds, at least, of major lighting manufacturers. Anyone who visits sites such as this one by USAI Lighting will see references to the Lighting Research Institute at RPI and the work of Mariana Figuero and her colleagues. These manufacturers have the tools, yet few designers understand the science involved in circadian lighting, much less the cost of tunable white systems- and particularly the controls needed for them to function in a useful manner.
The good news is that you don’t need tunable white lighting to achieve circadian stimulus in a day use only space, and you don’t need to completely eliminate computer and cell phone use at night.
