This IES LM-63 photometric file defines the asymmetric light distribution of the ERCO Parscoop I 33201000 wallwasher fixture. The ERCO Parscoop I 33201000 is a professional-grade wallwashing luminaire engineered for uniform vertical surface illumination. This photometric data set captures the specific light distribution characteristics produced by the fixture's internal reflector geometry and lamp source. It provides the necessary intensity values to accurately simulate how the light interacts with vertical planes, ensuring that designers can predict light spill, peak intensity, and gradient fall-off. The data is formatted as an industry-standard IES LM-63 file, which remains the primary method for communicating luminaire performance across various lighting simulation and architectural visualisation software platforms.

The download is a single file containing .IES files.

Lighting designers load this IES file directly into their illumination software to calculate accurate lux levels and light distribution patterns within a project. By assigning this profile to a light source in a 3D model, the software uses the mathematical data to cast light precisely as the real-world fixture would. This ensures that renders and quantitative analysis reflect the actual luminaire performance, allowing for precise placement and aiming of wallwashers during the design development stage of an architectural project.

This photometric data is essential for interior design projects requiring precise wall-washing effects, such as galleries, retail displays, and high-end residential lobbies. It is typically employed by lighting consultants during the technical design phase to verify uniform coverage on feature walls or artwork. Professionals search for this file when performing point-by-point lighting calculations or creating realistic light studies in software like DIALux, AGi32, or major 3D rendering engines to ensure accurate illumination of vertical surfaces in professional environments.
