A pleasant study environment in a better lighted NHL University of Applied Sciences

Posted on February 1st 2018 by Vincent Adema


In the ceiling of the study landscape, we’ve installed almost 150 Downlighters with LED technology. With a lifespan of over 80.000 hours, these will last for many years.


Good light creates a pleasant study environment

The right light can improve your energy and ability to focus. That’s why good light is very important for schools and universities. In the recent past, a large part of the light at the Noordelijke Hogeschool Leeuwarden (NHL University of Applied Sciences in Leeuwarden) had to be renewed.

The study landscape of the NHL is a long space with many light spots at 15 meters (almost 100 feet) high. The old fixtures used fluorescent lighting technology and this technology’s lifespan isn’t that long. Before the renovation, around 40% of the 150 fixtures was working.

As you can understand, replacing light at 15 meters (around 100 feet) high isn’t easy. That’s why choosing LED technology has been the right choice. First of all, it is more energy efficient than other light sources. That means you have to pay less for your energy bill and that you will operate in a more environmental friendly way. But LED also has a much longer lifespan than conventional light sources. Our LED modules have a lifespan of over 80.000 operating hours. This means that the fixtures will be working for many years, which means almost no service- and replacement costs.

A selection of the lecture halls has been relighted too. A problem the NHL was facing was that there wasn’t a lot of natural daylight in their lecture halls. When we lack daylight and high quality artificial light, we feel less energetic and alert. The client also wanted to have more control over the lights during the lectures.

That’s why the lecture halls use our Grammi inlay fixtures and they are driven by DALI light driver technology. The light can be controlled by a digital control panel. The intensity of the light can be adjusted easily through certain pre-programmed scenarios in the DALI software. There is a program with even light throughout the hall during interactive sessions, there is a lecture and presentation setting which dims the light everywhere except around the presenter, and finally there is a cleaning setting which puts the intensity on 100%.
