One thing most lighting professionals can agree on is there seems to be no universal agreement on what Human-Centric Lighting (HCL) means in practice. The philosophical underpinning of Human-Centric Lighting is generally a belief that lighting should promote the health, well-being, or comfort of users, but from there it gets more complicated. 

For example, some believe that Human-Centric Lighting should mimic natural light sources such as sunlight. Additionally, there are competing visions on how to design lighting for health or well-being. The priorities of specifiers and users also varies based on the setting. The designer’s view of ‘Human-Centric’ is greatly influenced by whether their lighting scheme is for hospital patients, school children, office workers, or assembly-line technicians in a factory. 

This poses a problem for luminaire manufacturers and lighting professionals alike. In general, manufacturers would prefer to make a strategic choice of a primary driver supplier—and even of a family of driver products—as it reduces the effort and time involved in vendor and product qualification. It also means that the manufacturer’s design engineers and installers only need to familiarize themselves with one set of features, technologies, programming tools, and so on.

On the other hand, for lighting and other specifying professionals, the fast-changing view in the market about how to meet the demand for a Human-Centric element to lighting means that the functional requirements of the driver are almost certain to change over time—varying greatly from installation to installation.

The challenge then becomes twofold:

  1. How can a single driver choice or driver supplier remain consistent while the luminaire’s specifications are ever-changing?
  2. How can luminaire manufacturers future-proof their preferred driver supplier while taking account of the different implementations of Human-Centric Lighting?
