QLumEdit

Eulumdat file types (LDT) are known to a small number of users that are familiar with photometry, the science of the measurement of light.

QlumEdit is a simple application that has been created to allow editing of this sort of file. It is easy to install on the system because the procedure requires following the instructions on the screen.

With a minimalist interface, the application allows creating new LDT files starting from a template; alternatively, it can be used to load new files.

There is a rich list of possibilities as far as templates are concerned because the developer included the possibility to select different properties for the light source, such as type and symmetry indicators and the type of the output flux.

To make things even easier, there are several light source examples (road luminaire, projector, fluorescent luminaire or floor standing uplight) included in the application.

Starting from this, you can customize the light source so that it fits your purpose. There is a rich selection of properties that can be modified, from details about the luminaire, and utilization factors to luminous intensity.

The application offers granular control over aspects like the width, length and height of the luminaire, diameter and height of the luminous area.

Working with QlumEdit is not for every user and neither is its configuration, despite the fact that there is little to tinker with.

The product can be instructed to fill the curves of luminous intensity in the diagram and to display the legend of the elements. Also, you get to choose the text line length of the LDT file.

QlumEdit targets a specific type of users and it provides a nice set of customization options that can fit most of the projects.
