Light means life. Every living organism has developed a unique relationship with the light spectrum. This becomes evident when we compare the needs of plants to those of humans. While humans are only able to see a small portion of the electromagnetic spectrum, plants are able to absorb and use a much broader sweep of wavelengths.
The light spectrum is the set of different wavelengths: some are visible to the human eye, some are not. And different wavelengths have different effects on living organisms. For example, some UV wavelengths play an essential role in the synthesis of vitamin D.
The human eye, instead, only perceives light within that narrow band of the spectrum we call ‘visible’ light. Natural light is crucial to human well-being. Not only does it let us see, it also regulates our circadian rhythms, influencing sleep patterns, moods and even productivity.
Optimise the spectrum for plant growth
Unlike humans, plants use light primarily for photosynthesis, a chemical process that converts sunlight, carbon dioxide and water into the glucose and oxygen plants need to survive.
To optimise plant growth, especially in controlled environments such as greenhouses, vertical farms or in soilless or hydroponic production, it’s essential to provide a suitable light spectrum.
LED plant lights let you tailor the spectrum to optimise each stage of growth. For example, blue light is often used to drive the vegetative phase, building strong roots and healthy leaves. Red light, on the other hand, is more effective during flowering and fruiting.
Furthermore, LED lamps, unlike other lighting solutions, give users access to a dynamic spectrum. This means they can adjust both light intensity and modulate the spectrum over the course of the day, or during the vegetative growth period, with obvious advantages: the natural day/night cycle can, in fact, be simulated by varying the red and blue elements. Seasonal changes in light can be reproduced and crop yields maximised.
The LED revolution in agriculture
For those seeking cutting-edge lighting for indoor growing facilities, C-Led leads the way with a wide range of LED products designed to optimise plant growth. LED lights, in fact, deliver a tailor-made spectrum, allowing dynamic regulation of light throughout every stage of plant development. Thanks to their adaptability and energy efficiency, LED lights enhance the indoor growing process and make it more sustainable. What’s more, compared to traditional lighting, the advanced light technology developed by C-Led – a Cefla group company – ensures a significantly longer working life and greater efficiency, with ‘smart’ lighting systems maximising crop yields and ensuring consistent quality
