Extract text from Photometric data files (GLD)
To convert GLD Data files to another format, you need DIALux or other Data software.
To convert other file formats to the "Photometric Data File" file type, you need software like DIALux or a similar tool.
A .GLD file primarily stores photometric luminaire data used by DIALux, a leading software for professional lighting design. It contains the technical specifications of light fixtures, including light distribution curves, physical dimensions, luminous flux, and energy consumption metrics.
The .GLD format is proprietary and closed to the DIALux ecosystem. This poses a major disadvantage: the file is completely unreadable by standard text editors, web browsers, or general 3D modeling software. Users often need to convert these files to industry-standard photometric formats like IES or LDT (EULUMDAT) to share lighting data with engineers who use different CAD or BIM tools. Standard online converters fail to process .GLD files because translating the complex 3D geometry and photometric matrices requires the original software engine.
In rarer cases, a .GLD file functions as a compiler linker script for MPLAB, a game log data file, or a Ground Loop Design Work file created by Thermal Dynamics.
Because this file format is highly specialized and difficult to open or convert, often only the original software can properly read or export the data. Just drag and drop your file to identify the exact format, view it, and convert it when possible using convert.guru. If our analysis detects a supported underlying or embedded format, text viewing or data extraction may still be possible.
Convert.Guru analyzes your GLD file, detects the exact format, and lets you read the text inside.
Users also converted GLB, ELG, SAL and CEV files.
If you want to convert GLD file to JS, TS, PY, JAVA, CPP, C, CS, PHP, RB, GO, RS or SWIFT, you can use DIALux or similar software from the "Lighting Design Data Storage" category. In the File menu, look for Save As… or Export….
To convert SH, PY, KT, PS1, SWIFT, LUA, PL, JAVA, SCALA, JS, VBS or TS files to GLD, try DIALux or another comparable tool in the "Lighting Design Data Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our GLD converter.
