This IES LM-63 photometric file defines the light distribution for a Lithonia KVS1 area luminaire using a 250W HPS light source. The Lithonia KVS1 is a traditional area luminaire designed for high-intensity discharge lamps, specifically configured here for a 250W high-pressure sodium (HPS) source. This photometric file captures the light distribution pattern characteristic of a Type II medium cutoff optic. It provides the necessary mathematical data to simulate the luminaire's output, beam spread, and intensity distribution in lighting analysis software. The file adheres to the IES LM-63 standard, ensuring compatibility with industry-standard design tools for calculating illuminance levels, uniformity ratios, and light trespass in exterior environments.

The download is a single file containing .IES files.

Lighting designers and electrical engineers load this IES file directly into their lighting calculation software or 3D rendering engines. By mapping this data to a light source object, users can accurately project the real-world light distribution of the KVS1 luminaire. It is essential to ensure the photometric web is correctly oriented relative to the fixture's mounting position to achieve precise results for site lighting layouts, parking lot illumination studies, or roadway lighting designs.

This asset is intended for use in professional exterior lighting design projects, particularly for municipal, industrial, or commercial parking facility applications. It is invaluable during the schematic design and development phases when performing point-by-point illuminance calculations to meet local code requirements or dark-sky ordinances. Professionals searching for photometric data for outdoor area lighting, street illumination, or security lighting will find this file provides the necessary technical accuracy for simulating HPS-based lighting solutions in large-scale site plans.
