Lighting on yachts is more than just a function – it creates atmosphere, provides orientation, and is a mark of quality.
But how can you truly recognise good lighting? In this article, we explain what lies behind terms such as lumens, lux, and CRI – and why it pays to take a closer look when choosing marine lighting.
Lumens and Lux – what measures what?
When we talk about light, lumens and lux are two of the most important technical terms.
- Lumens (lm) describe the total amount of light emitted by a light source – in other words, its brightness.
- Lux (lx) measure how much of that light actually reaches a surface – for example, the chart table, the companionway, or the foredeck.
At sea – especially at night – focused, glare-free lighting is essential. Knowing how much lux is appropriate in each area not only enhances comfort, but also significantly improves safety.
CRI – the art of seeing colours correctly
The Colour Rendering Index (CRI) measures how accurately a light source reproduces colours. The scale ranges from 0 to 100 – the higher the value, the more natural colours appear under that light.
For yacht owners, this means that a high CRI value (above 90) ensures teak wood looks warm, charts remain high in contrast, and cabin fabrics appear true to life – without the flat, clinical feel often associated with LEDs.
Our Cabin lights achieve CRI values of up to 98 – delivering natural colours and a refined ambience that belongs on high-quality yachts.
Lamp? Light? Marine lamp? The subtle difference.
Often used synonymously in everyday language, these terms deserve a closer look:
- The marine lamp refers to the light source itself – for example, the LED.
- The marine light (luminaire) is the complete unit: housing, electronics, and light source – what you install and see.
At Cabin Denmark, we manufacture marine lights that are thoughtfully designed both technically and aesthetically – featuring stainless steel housings, marine-grade electronics, and a design that blends unobtrusively into any cabin.
Conclusion: Technical expertise that shines with style
Those who pay attention to values such as lumens, lux, and CRI when it comes to onboard lighting – and who understand what truly matters in a genuine marine light – make a conscious choice for quality, safety, and refined aesthetics.
Our recommendation: Choose durable lights with high colour rendering, well-balanced light distribution, and a design that not only illuminates your yacht, but enhances it.
