Sustainable Light(ing)

Sustainable light requires the integration of effective daylighting strategies with quality electric lighting to create a sustainable visual experience.  Quality lighting that is energy efficient is sustainable.  Bartholomew Lighting is committed to creating designs that have the least impact on the environment, while supporting a quality visual experience for the occupant. 

Healthy Light(ing)

Bartholomew Lighting strives to design lighting that balances the visual and biological needs of the occupant.  One of the methods is to design lighting and controls that support circadian synchronization through the effective use of daylighting and dynamically controlled light spectrum.  Lighting can be used to mitigate noise and provide germicidal UV to deactivate and kill pathogens in the air and on surfaces.  These healthy light solutions must be carefully integrated with mechanical HVAC systems that revitalize occupant health and well being.
