Lighting Engineering Services Required

We require specific expertise to deliver the development of a second-generation lighting technology which builds on our early stage prototypes and product trials and includes the following key components:

  • Integrated water-cooling optimising excess heat output removal and reducing OPEX on system ventilation and cooling

  • Up to six separate LED strings made up of phosphor multi-wavelengths and narrow spectra

  • Unparalleled light uniformity close to the crop

  • Exceptional light-energy output, reducing energy use

  • Product design and prototype assembly, including the management of external suppliers  

  • Overseeing pre-production of manufacture and making necessary product amends

  • Product testing and evaluation to verify spectra and specification.

  • Delivery of the product through safety certification

  • Full supply chain management including shipping of products to the UK

The finished product will be a fully operational, optimised and integrated, yield-boosting lighting and nutrient delivery system.  The product will be scalable and designed to integrate with current commercial production systems for controlled environment agriculture and vertical farming.  

We require a range of inter-disciplinary skillsets to work with us and oversee this complex and multi-faceted project, engaging with project stakeholders to deliver a successful outcome.

The partners will work under our in-house, full-time, PRINCE2 certified Project Manager, whose main responsibilities include: (1) Coordinating the delivery of all project activities; (2) Managing the communications plan; and (3) Serving as the project’s contact point for interfaces with the funding authority and other external stakeholders.
