This IES LM-63 photometric file provides precise light distribution data for the Lithonia BLWP4 4-foot LED wraparound luminaire. The Lithonia BLWP4 is a linear LED wraparound luminaire featuring a square prismatic lens designed to provide uniform light distribution across broad interior spaces. This photometric profile captures the specific luminous intensity distribution of the fixture, accounting for the diffusion properties of the prismatic lens and the integrated LED source. It is engineered for high-performance illumination in environments requiring consistent, glare-controlled overhead lighting. The data represents the standard configuration of this fixture, ensuring that lighting calculations accurately reflect the luminaire's output characteristics in both new construction and retrofit lighting design projects.

The download is a 10 KB file containing .IES files.

Lighting designers and electrical engineers load this IES file into their lighting analysis software or BIM environments to simulate real-world light levels and uniformity. By applying the photometric web to a generic or manufacturer-specific light source object, users can generate accurate illuminance maps, calculate foot-candle levels, and verify compliance with energy codes. The file allows for precise placement within ceiling-mounted lighting layouts, ensuring that the simulated output matches the physical performance of the specified Lithonia luminaire in the final design.

This photometric data is essential for professional lighting design in commercial, industrial, and institutional applications. It is frequently employed in the planning stages for office corridors, retail storage areas, hospital utility rooms, and educational facility hallways where functional, long-lasting illumination is required. Professionals use this data to perform point-by-point lighting analysis and verify the spacing criteria for uniform light coverage. It pairs effectively with other industrial-grade lighting components and is a standard requirement for verifying project-specific light level specifications in complex building environments.
