With DIALux Mobile, you can quickly carry out light planning of an interior space with real products directly on site on your smartphone or tablet.
With this app you can gather information about a room and create a lighting system. You will immediately receive details of the number of luminaires and their positions that are needed to meet the normative requirements for lighting a room.

Step 1 – Create a new project:
Define the dimensions of the room and select or enter the nominal values for the lighting system yourself in the user profile. You can also easily enter parameters such as degrees of reflectance and the room's maintenance factor.

Step 2 – Select luminaires:
Select a suitable luminaire from an online database comprising real products from leading manufacturers. Based on this database, you will receive the calculation results for the room on your smartphone or tablet. You can immediately see how many luminaires are required and the level of illuminance achieved is clearly displayed.

Step 3 – The result:
The result provides you with a plan of the room which includes the luminaires, the illuminance and information about energy consumption.
