DIALux Overview

What is DIALux?

DIALux is the world’s leading software platform for professional lighting design, calculation, and visualization, trusted by over 750,000 users worldwide. Developed by DIAL, a company based in Lüdenscheid, Germany, DIALux has set the industry standard since its launch in 1994, serving lighting designers, architects, engineers, and planners in more than 26 languages and across a wide range of project types. At its core, DIALux simplifies the entire lighting design process for both indoor and outdoor environments. Users can create lighting concepts for individual rooms, multi-storey buildings, streets, car parks, and outdoor areas, all while working with real luminaires from over 400 renowned manufacturers. The software enables the import of 3D BIM models, DWG plans, and room scans, allowing for flexible placement and arrangement of luminaires. Powerful calculation and visualization tools ensure that lighting designs are both technically precise and visually compelling, meeting international and regional standards for safety and efficiency. DIALux is available for free and provides comprehensive tools for designing, calculating, and visualizing lighting. It supports projects ranging from simple rooms to complex buildings and outdoor spaces. DIALux also includes features for emergency lighting, enabling planners to design escape routes and anti-panic areas in compliance with safety standards. Users can access a vast database of over 1.9 million luminaires, ensuring the right product selection for every project. Additional features are available with a DIALux Pro. This advanced, subscription-based version is tailored for professionals seeking enhanced productivity and workflow optimization. DIALux Pro introduces features such as Open BIM integration (import/export of IFC files), advanced export options (to formats like Word, Excel, and PowerPoint), custom documentation layouts, and the ability to use luminaires from non-member manufacturers. These tools streamline the design process and facilitate collaboration across project teams. DIALux also fosters a vibrant community where users can exchange ideas, share projects, and influence future software development. The DIALux Academy offers tutorials, seminars, and online courses, empowering users to master both lighting design and the software itself. The business model behind DIALux ensures that the core software remains free for users, funded by memberships from luminaire manufacturers and optional paid add-ons or Pro subscriptions for advanced features. In summary, DIALux is a comprehensive, industry-leading ecosystem that empowers lighting professionals to design, calculate, and visualize lighting solutions for any environment, combining technical precision with creative flexibility and supported by a global community and extensive manufacturer partnerships.

What do you like best about DIALux?

VERY HELPFU IN MAKING LIGHTING DESIGN FOR ANY TIME OF BUILDING AND ALSO THE DESING IS IMPLEMENTED USING REALTIME SINERIO AND ITS EASY TO SEE WHAT WILL BE THE PROBLENMS BEFORE ORDERING MATERIAL REAL TIME AT SITE. IT GIVE A BROAD VIEW OF THE MY WORK BEFORE PRESENTING IT TO THE CLIENT AND GIVE ME CONFODENCE ON WHAT I AM RECOMMENDING TO THE CLIENT. Review collected by and hosted on G2.com.

What do you dislike about DIALux?

THE THING WHICH I DISLIKE THE MOST ABOUT THE DILUX IS IT LIGHTING SELECTION FROM DIFFERENT MANUFACTURE AND IS ONLY GOOD AND FIT FOR THE DEVELOP COUNTRIES BUT IN SOUTHASIAN COUNTRIES WHERE THEIR IS PROBLEM OF DIFFERENT MANUFACTURER LIMITED LIGHT FIXTURE AVAILABILITY IS THAT IF WE CONDISERED SOME LIGHT FROM DIALUX LIGHT FIXTURE CATALOG I MAY OR MAY NOT BE AVAILABLE .SO BEFORE MAKING ANY DESIGN I HAVE TO CONSIDERED THAT LIGHT THAT I AM PROPOSING FOR SOME CLIENT IS EASILY AVAILABLE IN THE MARKET.OFFCOURSE DIALUX HAS NOT TO DOMUCH WITH THIS PROBLEM BUT THEY CAN HELP IN THIS REGARDS.

SO BASICALLY ITS A OBSERVATION FOR THE IMPROVEMENT OF THE SOFTWARE USEFULL NESS AND INDUSTRY PROBLEM THAT ANY LIGHTING DESIGNING FACE IN UNDER DEVELOP COUNTRY. Review collected by and hosted on G2.com.

Recommendations to others considering DIALux:

use dialux for lighting designing but before that if you are working on already build architecture drawing first you have to rebuilt the same wall and floor layout and then add light fixture as per your requirement.it can also import file from autocad in 2d for clear understanding of the required area for analysis and desining.

Dialux is free software so thank to dialus for providing support to the concerned industry professionals. Review collected by and hosted on G2.com.
