This IES photometric file for the ERCO Trion 33440000 uplight provides precise light distribution data for indirect ceiling-wash lighting. The ERCO Trion 33440000 is an indirect lighting fixture designed for uniform ceiling illumination. This photometric file captures the specific light output characteristics of the luminaire when equipped with a 120W QT-DE12 lamp. It provides the essential intensity distribution data required for accurate lighting simulation in professional design software. As a standard LM-63 formatted file, it represents the optical performance of the fixture, ensuring that lighting calculations for indirect ceiling wash applications remain consistent with manufacturer specifications. The data is structured for integration into lighting analysis tools to predict luminance levels accurately.

The download is a single file containing .IES files.

Engineers and lighting designers load this IES file directly into lighting calculation software such as DIALux or AGi32, or import it into BIM and 3D rendering applications that support photometric webs. By assigning this profile to a light source object, users can simulate the indirect light spill and ceiling wash effect within a virtual model. The file ensures that both the light intensity and the beam spread are calculated according to the physical properties of the original ERCO fixture.

This photometric data is intended for use in professional lighting design projects where accurate ceiling illumination is a requirement. It is particularly suitable for office spaces, lobby areas, and high-end residential interiors where indirect, glare-free lighting is desired. Architects and lighting consultants use these files during the design development and technical documentation stages to verify light levels and uniformity across large ceiling planes. It pairs effectively with other ERCO luminaires for comprehensive interior lighting schemes, ensuring consistent light quality and technical accuracy throughout the building.
