Content DescriptionThe ability to emit radiant power in hundreds or thousands of spectral combinations—only limited by the precision of the control signal being provided—poses a distinct challenge for measuring product performance. This TM establishes a common protocol for measuring photometric, colorimetric, and electrical characteristics of tunable-white solid-state lighting products—including lamps, luminaires, and light engines. It defines the minimum number and order in which measurements are to be made, and it provides a framework for data reporting. This TM also describes a method for interpolating between measured data, including for CCT range, Duv range, lumen output range (at full intensity control as color changes), efficacy at maximum output, efficacy range, color rendition, and chromaticity coordinates. The protocol described herein applies to products for which the spectral power distribution can be adjusted with a single, one-dimensional input having a quantitative, interval format, either continuous or discrete, that is nominally independent of luminous flux control. The method described does not apply to products that intentionally change chromaticity with luminous flux (e.g., dim-to-warm), or products with multiple color-control input signals (e.g., full-color-tunable) that cannot be set to operate with a single color-control input signal.This book also exists in the following packages...Subscription InformationMADCAD.com IES subscriptions are annual and access is concurrency based (number of people that can access the subscription at any given time).
