On Construction site MORE 1 & 2 in Leiden apply the same tower crane frame concept as at Van der Spek, in collaboration with Ballast Nedam Materieel and Heddes, but here it earned them the prize for Best Performing Construction Site in the Netherlands.
The innovation for which the construction site was nominated was the use of DarkLicht fixtures in the tower cranes. By using smaller and LED lamps, four instead of three fixtures can be mounted on the faucet.
Just like with Van der Spek, the challenge was to limit light pollution for the surrounding area and maximize energy savings, while ensuring the work environment around the crane remained well-lit at varying heights.
In the urban context of Leiden, with residents and nature in the immediate vicinity, limiting nuisance was particularly important.
JEL had already developed a reusable crane frame concept with Van der Spek. For construction sites MORE 1 & 2 in Leiden, the same concept was applied, together with Ballast Nedam Materieel and Heddes.
By using DarkLicht fixtures in the frame, the light shines exclusively on the construction site. This approach not only resulted in significant energy savings but also earned the company the national award for Best Performing Construction Site.

Construction site lighting using tower crane frames (award-winning project)
Leiden, Netherlands (project MORE 1 & 2)
Heddes Construction & Development / Ballast Nedam Equipment
Urban construction site with residents and nature in the immediate vicinity
Application of the proven JEL crane frame concept with DarkLicht fixtures.
Lighting design and engineering; supply of DarkLicht crane frames (design similar to that used by Van der Spek).
DarkLicht fixtures in crane frames, more than 100 frames
73%: Energy savings and significantly reduced light pollution; Best-Performing Construction Site in the Netherlands.
EN 12464-2, NSVV guideline on light pollution, and the Machinery Directive (for the frame).
The approach is based on the crane frame concept developed in 2019, which was further refined in 2021 with DarkLicht luminaires integrated into the frame. The lights can be adjusted with great precision so that the light shines only on the construction site, causing much less disruption to nearby residents, the surrounding area, and nature.
More than 100 tower crane frames have been supplied for Ballast Nedam and Heddes for their cranes.
JEL supplied the DarkLicht crane frames and the lighting design for the tower cranes at the MORE 1 & 2 construction site in Leiden, in collaboration with Ballast Nedam Materieel and Heddes.
The light is designed and adjustable so that it illuminates only the construction site, at varying crane heights and in accordance with EN 12464-2.
The solution builds on the JEL crane frame, which was developed in 2019 and further refined in 2021 by DarkLicht, and is used in collaboration with Ballast Nedam Materieel.
Because the DarkLicht fixtures are smaller and use LEDs, four can be mounted on the crane instead of three, with a precisely adjustable light beam.
Because the light is exclusively focused on the construction site, residents, the surrounding area, and nature experience much less disruption, which is important in the urban context of Leiden.
The switch to DarkLicht in the crane frame resulted in energy savings of no less than 73%.
The combination of energy saving and minimal light pollution made MORE 1 & 2 in Leiden the Best Performing Construction Site in the Netherlands; for Ballast Nedam and Heddes, more than 100 crane frames have been delivered.
The project resulted in energy savings of no less than 73% and significantly reduced light pollution in the surrounding area. As a result, the MORE 1 & 2 construction site in Leiden was named Best Performing Construction Site in the Netherlands.
The project demonstrates how thoughtful lighting not only saves energy but also directly contributes to an award-winning, environmentally conscious construction site.
The tower cranes are equipped with DarkLicht luminaires in the JEL faucet frame. Because these lamps are smaller and work with LEDs, four can fit instead of three on the faucet, with a precisely adjustable light beam.
For all cranes from Ballast Nedam and Heddes combined, more than 100 tower crane frames have been supplied.
This was achieved, in part, through the use of DarkLicht light fixtures on the tower cranes, in collaboration with Ballast Nedam Materieel. Thanks to smaller LED bulbs, four light fixtures—instead of three—can be mounted on the crane, and they can be adjusted so that the light shines only on the construction site.
The DarkLicht fixtures are precisely adjustable, ensuring that light is directed exclusively toward the construction site and that nearby residents, the surrounding area, and nature experience much less disruption.
This step results in energy savings of as much as 73%.
It is based on the same crane frame concept developed in 2019, which was further refined in 2021 with DarkLicht attachments integrated into the frame. More than 100 tower crane frames have been delivered to Ballast Nedam and Heddes.
More than 100 tower crane frames have been delivered to Ballast Nedam and Heddes combined, based on the JEL crane frame developed in 2019 and further refined in 2021 with the DarkLicht.
