This IES photometric file provides precise light distribution data for the HALO HL3 20W square LED wall wash luminaire. The HALO HL3 20W square LED wall wash is a recessed luminaire engineered for uniform vertical surface illumination. This photometric dataset encapsulates the specific light output characteristics, including beam spread, intensity distribution, and efficiency metrics associated with the 20W LED source. As a standardized LM-63 file, it captures the essential light emission profile required for accurate architectural lighting simulations. The data reflects the luminaire's design intent to provide smooth, consistent wall washing in commercial and residential interior applications while maintaining high color rendering performance for architectural features and vertical planes.

The download is a single file containing .IES files.

Lighting designers load this IES file into their chosen lighting analysis or rendering software to simulate real-world light distribution. By assigning the file to a light source object, the software uses the documented intensity values to generate accurate light patterns, shadows, and spill. It is essential to ensure that the luminaire geometry in the scene is correctly aligned with the photometric web's orientation to achieve the intended wall-washing effect during the simulation process.

This photometric data is intended for use in lighting design projects requiring precise vertical surface illumination, such as art galleries, high-end retail displays, and feature walls in hospitality or residential lobbies. It is particularly useful during the schematic design and development phases when calculating illuminance levels and verifying glare control. Architects and lighting consultants use these files to ensure that the specified HALO fixtures meet project performance criteria and energy codes for effective space lighting across various interior environments.
