Installation of LED Grow Lights In Transgenic Glasshouses

Customer Name

University of Leeds


Contract awarded July 2017. Completed in October 2017.


Leeds University has nine transgenic glasshouses which were constructed in 2003.

One of the greenhouses was recently fitted with LED luminaires as part of a feasibility study into the performance of the lighting system and the impact on plant growth. The study was positive and Leeds Uni required seven of the remaining greenhouses to be converted to LED luminaires


  • General complexity of the project
  • Greenhouse structure and lack of solid material for fixtures
  • Site restrictions
  • Greenhouses were in use
  • Solution to allow certain lighting rows to be dimmed

Actions and Solutions

The project consisted of providing and installing 84 PhytoLux LED lights alongside 28 lighting racks units across the seven greenhouses.

Leeds University required 3 of the 4 racks in each of the greenhouses to be adjustable in height so a single pulley system (rigs) was also installed while the 4th lighting array was fixed directly to the fabricated unistrut.

90% of the rigs were constructed in the Remark Group’s workshop prior to transportation to reduce downtime in the greenhouses which were in operation. Each of the greenhouses had to be completed prior to moving onto the next one to minimising downtime and disruptions for the university.

Once erected the luminaires were connected to local switches via heavy duty coiled flex. All fixings and materials used had to be suitable for the various environmental conditions modelled in the greenhouses.

The Remark Group ensured that our technicians work was carried out in a safe, clean and professional standard to reflect Remarks core principles and values for our client.
