We support both linefit and retrofit projects with comprehensive cabin lighting expertise.
Implementation process.
We support both linefit and retrofit projects throughout the entire process – from initial ITCM meetings to final handover – covering all aspects of cabin lighting, including galleys, lavatories, and CRCs. Our team combines lighting expertise with in-depth aerospace systems knowledge, allowing us to enter a project at any stage, even shortly before the first cabin lighting workshop. This makes us a reliable partner for coordinating the full lighting process and supporting airline teams – even those without prior lighting experience. Ideally, we’re involved from the very beginning, bringing all relevant stakeholders to the table and guiding the implementation through our proven four-step approach.
