How do Golnoor photometric files help?

A photometric file imports the product's technical and lighting data into a DIALux project. Product selection is therefore based on measured data, not appearance alone.

Should I use the online or offline plugin?

Download the offline plugin if you want the product database installed on your system. Use the online plugin to search and select products on the web.

What projects is DIALux evo suitable for?

DIALux evo can be used for rooms and offices as well as commercial, industrial, parking, outdoor, and road lighting projects.

Can DIALux calculate daylight and emergency lighting?

Yes. DIALux evo supports artificial light, daylight, and emergency lighting calculations across different project scenarios.

Do I need specialist knowledge to get started?

Professional use benefits from lighting design knowledge, but the page and Golnoor resources are organized to make the first steps easier.

What is the difference between the online and offline plugins?

The online plugin is suited to quick product search and selection on the web. The offline plugin makes the product library available on your system.

Is the Golnoor photometric data limited to one product?

No. The collaboration library includes photometric files for different Golnoor products so you can select and compare the right product for each project.

What do I get after calculating in DIALux?

You can prepare scenario results, lighting metrics, and a project report for technical review, presentation, and final decisions.
