Converging lighting technologies – April 2023 Newsletter

The Principal´s Pen

It’s autumn in the Southern Hemisphere, the leaves of the oak and other trees are changing colour and will soon loose their leaves before winter arrives.  Similarly,  The mode of people also changes with the seasons.

In the world of lighting technologies have been rapidly converging, this has been taking place since 2016.  I presented many workshops around South Africa to inform architects, consulting engineers and people in the lighting industry about these industry advances but despite educating those who attended, it is astounding that there has been such minimal projects where the exciting new integrated lighting technologies have been used.

Clients have been the losers.  The new integrated lighting technologies when used effectively, make the lighting on a project much more energy efficient.  In these times of scheduled blackouts, it is so important to use every technology to reduce energy consumption.  Businesses, architects and consulting electrical engineers focus on solar and inverter technologies and forget about lighting technologies to compliment the overall effort to be most energy efficient.

Many professionals have the idea that the new technologies are more expensive.  The opposite is true.  As with anything that is relatively new or different from the the familiar everyday lighting, one has to take time to study the technology and learn how to design the system architecture before being confident to specify the use in lighting designs.

Our graduates are well versed in the technologies, they know how to design the system architecture and how to specify then for projects.

Students who have almost completed the Relux Desktop module in the Advanced Diploma course and those who have enrolled for the Relux Desktop short course, which incidentally is the same as the module in the Advanced Diploma course, are absolutely amazed at the capabilities of the software.  Of course the students on the Advanced Diploma learn how to include the new technologies and several other standards including those for Visually Demanding tasks.

We are encouraged to note that some progressive lighting distribution companies continue to enroll staff for different courses, including the Relux Desktop course.

Be sure to register for our next webinar on 20 April 2023 – “Episode 4/23: Dialux Evo versus Relux Desktop 2023 – A factual comparison by experts and me”.  The features of each software suite will be compared. We will discuss expert evaluation results and the results of research into the accuracy of each suite.  I will give my reasons for choosing the suite that we use with great success.

I wish you all great business and good health.

With best regards

About: Many webinar attendees have requested this topic to be presented. The comparison is based on facts and the evaluation of both software suites as well as other software by international experts and the University of Athens.  I will also provide you with the reasons why we have chosen to use Relux Desktop. We hope that this will answer your questions about which lighting design software to select.
