Lithonia BLT 2x4 LED Troffer 2BLT2 IES file providing precise photometric data for accurate interior lighting simulation and analysis. This IES LM-63 standard photometric file represents the light output characteristics of the Lithonia BLT 2x4 AIR LED troffer. It captures the specific distribution patterns, intensity, and beam angle profiles of the luminaire, which features a curved linear prismatic lens. Designed for recessed ceiling applications, the data reflects the performance of the 4000K colour temperature variant with an output of approximately 4000 lumens. This file enables professional lighting designers to predict illuminance levels, uniformity, and light distribution accurately within digital models, ensuring compliance with energy codes and specific project lighting requirements for commercial environments.

The download is a single file containing .IES files.

To use this photometric file, load the IES data into your lighting simulation software or BIM environment such as Revit, DIALux, or AGI32. Apply the profile to a generic or manufacturer-provided light source geometry to simulate real-world light distribution. Adjust the intensity settings and light placement within your project to match the intended ceiling layout. The file maps the light emission pattern, allowing for realistic rendering and technical light level calculations in interior spaces.

This photometric data is essential for architects and lighting engineers working on commercial, institutional, and healthcare projects. It is primarily used during the design and development stages to verify that lighting layouts meet required lux levels for offices, classrooms, corridors, and retail showrooms. By integrating this file, professionals can perform detailed lighting analysis to ensure optimal visual comfort and energy efficiency. It is a critical resource when specifying standard recessed ceiling lighting for large-scale interiors where precise light distribution is mandatory.
