Relying on tunable white light is the “best, most-affordable way to ‘future-proof’ your work and designs and ensure very high performance.” So said Terry Clark, Founder and Chairman of the Board of Finelite, Inc., while participating in the National Lighting Bureau’s Annual Lighting Forum as one of three panelists focused on new and emerging developments […]
Applications for Tunable-White Lighting
Guest post by Steve Mesh, LC Because of recent trends in the lighting industry, it is now possible to “dial in” a desired color temperature in certain light fixtures at specific times of the day or night. One of the main trends making this possible is the mixture of different color LEDs in architectural fixtures. […]
Interview with Acuity Brands’ David Ciccarelli on Tunable-White Lighting
Craig DiLouie, LC recently had the opportunity to interview David Ciccarelli, VP Dynamic Lighting, Acuity Brands Lighting, Inc. The topic: tunable-white lighting. DiLouie: Looking at LED sources and controls, what are the different technological methods used to produce tunable-white light in commercial luminaires? Ciccarelli: The goal of Tunable White lighting is to reproduce multiple color […]
White-Tunable LED Lighting
LED lighting can generate virtually any perceivable color as well as any shade of white light, all digitally controlled and selectable. Color output can be adjusted by mixing color LEDs, mixing white-light LEDs of different color temperatures, or a combination of the two. The key to achieving these effects is dimming. This allows, for example, […]
CRI Modulation: Future Lighting Control Strategy?
LED lighting has made a new dimension of lighting control, color tuning, widely available. By mixing separately dimmable arrays of warm- and cool-white, saturated colors (RGB+A) or a mix of the two, correlated color temperature (CCT) can be tuned manually or automatically based on various application needs. Besides CCT, the source’s color rendering index (CRI) […]
White Light Color Tuning Offers a New Dimension of Lighting Control
Light is comprised of wavelengths that the human eye interprets as colors. For an object to be perceived a certain color, that color must be present both in the light striking an object and the object reflecting the light towards the observer’s eye. Because of this, the choice of lamp for white-light general lighting can […]
