Healthy lighting for non-residential structures centers is based on usage. Hospitals have different requirements than warehouses or schools. Yet a healthy light environment still must take into account our circadian  wellbeing regardless of setting. The lighting fixtures themselves cover a wide range of designs and limitations. Control systems may involve nothing more complicated than a switch that allows for temperature tuning and brightness. More complex systems may control light temperature and brightness that varies due to room usage, exposure to outside light and demands for an accurate Color Rendering Index (CRI).

The opportunity for effective disease control through use of UV-C LED technology also exists in ways never before possible. UV-C LEDs are able to replace Mercury based bulbs with more effective (better microbe destruction) and non toxic (no Mercury) lighting systems.

The basic issue is availability of tunable lighting that enhances our health through effective use of circadian sunlight cycles indoors. The lighting itself may take a number of forms from bulbs, tubes or panels. Control of tunable lighting again comes in different forms from simple switches to computerized systems. For disease control the issue is supplying an effective UV-C spectrum LED system that eliminates airborne microbes and that does not directly expose users to harmful UV-C.

The good news is that products exist in both tunable circadian systems and in disease controlling UV-C LEDs. The bad news is that many worthwhile products are hidden by marketing information that obscures basic tuning information. In the case of UV-C much information attempts to sell either obsolescing Mercury based product or other LEDs which do not offer the most effective disinfecting range (260 – 280 nanometers) of UV-C.
