This IES LM-63 photometric file provides precise light distribution data for the HALO Span T5 fluorescent wall wash luminaire. The HALO Span T5 wall wash (LF4025239AH) is designed for professional architectural illumination, focusing on uniform vertical surface coverage. This IES file captures the specific light output characteristics, including the beam spread and intensity distribution, essential for accurate lighting calculations. The fixture features a specular reflector and a blade louver system, engineered to direct light efficiently while minimizing glare. By utilizing this photometric data, lighting designers can simulate the exact performance of the luminaire within a space, ensuring that wall-washing effects meet required illuminance levels and uniformity standards for interior environments.

The download is a single file containing .IES files.

Lighting professionals import this IES file directly into lighting analysis software or BIM environments to simulate real-world illumination. By assigning the profile to a light source object, users can accurately predict light spread, intensity, and shadow patterns on vertical surfaces. It is essential to ensure the luminaire is correctly positioned and oriented within the model to reflect the manufacturer's specified mounting height and spacing, allowing for precise verification of lighting designs during the schematic and development phases of a project.

This photometric data is intended for use in commercial, retail, and institutional projects where high-quality vertical illumination is required. It is commonly specified for illuminating feature walls, signage, corridors, and gallery spaces in offices, hotels, and healthcare facilities. Lighting designers rely on such data to create accurate renderings and calculate foot-candle or lux levels, ensuring that the final installation matches the design intent. Use this file when performing detailed lighting studies or planning illumination layouts for large-scale interior architectural applications.
