Research of the Characteristics of a Modular Luminaire with LEDs for Outdoor Lighting

This article presents the results of the study of electrical, light, and spectral characteristics of the Lisma Module M1 MK‑3 81W outdoor LED modular luminaire. The measurement results were compared with the values of the characteristics declared by the manufacturer in order to identify the accuracy of the declared rated parameters. The studies demonstrated that luminous flux, luminous efficacy, and power capacity of the device are virtually identical to the values declared by the manufacturer (within the tolerance limits). The luminaire has good colour rendering and rather soft radiation spectrum with chromaticity corresponding to neutral white light. The structure of the studied LED device is described. The studied luminaire is compared to other LED lighting devices manufactured in Russia. The recommendations regarding application of the studied LED luminaire are provided.
