What is a LUT file

LUT files mostly belong to RadioRA Essentials by Lutron Electronics. The LUT file extension is often associated with files that are related to lookup tables. The term 'lookup table', in technical language, is mostly used to refer to files that stores algorithm used for transforming data.

• Main Usage: A LUT file or a lookup table file contains algorithms of transformation. This transformation can be the process of adding effects to image files or any other process.
• More Information: Here is a list of files/programs that uses LUT file extensions:
• • XnView LUT Configuration: XnView, a picture/image digital editing and converting application, uses LUT file extension for its configuration data files.
  • ENVI lookup table: ENVI, a program by Esri, is used to store and analyze geospatial images. It also uses the LUT file extension. It uses the LUT format for its lookup table files.

• Associations:
• • RadioRA Essential Project Database: RadioRA, a program by Lutron, helps in setting up wireless home control systems. It also uses the LUT file extension. These LUT files contain configuration settings and control details of a thermostat and electric or light devices of a building or a house.

LUT format details:

Why is it important to know the file format? This is the only way to find out which program to use to open the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. However, different programs can use the same file extension, and file extensions can be assigned incorrectly. When there is a problem with a file, the first step to solving it is to determine the file format. Our examination of the LUT files comes to the following conclusion:

The LUT extension is quite commonly used. The file itself is used by a few programs, each with its own file format. But the following two file formats are common:

• 45% of all LUT files start with the bytes 30 7C crucial for this file format. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. LUT files are between 64 bytes and 320 bytes in size. It is a modern file type. Examples of file names are power.lut or throttle.lut. These files are often associated with tcurve, front, height, rear, medium, diffuser, hoosierr, torque, soft and tyre.
• 4% of all LUT files start with the bytes -10|, which are crucial for this file format. These files are text files and can therefore be read using a text editor. The files are 45 bytes to 100 bytes in size, with a median of 78 bytes. Examples of file names are wing_body_AOA_CD.lut or wing_body_AOA_CL.lut. Such LUT files store data about wing and body.

All other LUT files (51%) have no uniform format, the following 8 formats can be found: Houdini LUT, Formula and ICOL. Files like these are sometimes linked to kers, rainbow, blackbdy, tempfile, recommended, semislicks, frontwing, perfcurve, brodmann, stronger, colors, engine, noclip, shades, street, bwear, crazy, curve, semis, speed, cyan, gear or hard.
