In just the last five years, LEDs have completely transformed the lighting landscape. Originally embraced as an energy-saving option for lighting retrofits and code compliance, lighting professionals and their customers often had to compromise – efficiency versus ambience. Not anymore. LED lighting offers a wide variety of advantages including excellent color rendering and superb dimming capability. Tunable white is the current hot topic, and digital control is essential for making the most of white tuning potential.
White tuning research is still relatively new, but the evidence increasingly points to a wide variety of human-centric benefits, and potentially even health benefits, that can be realized through control of fixture color temperature. Specific, physiological benefits are still unclear, but there is no question about the aesthetic value and flexibility white tuning provides. Lighting designers and specifiers are looking for a simple way to use this new technology to better meet their customers’ needs. When considering your options, digital controls far surpass the performance of analog control, and will often end up being both simpler to design and even less expensive than 0-10V.
