Luminous flux is a fundamental concept in the field of lighting, representing a quantitative measure of the amount of visible light emitted by a light source in all directions and perceived by the human eye.
It is measured in lumens (lm), which is the unit of the International System of Units applied to this criterion. This concept is highly relevant to understanding how different light sources illuminate spaces and how that light is perceived by humans.
The lumen (lm), as a unit of measurement, takes into account not only the amount of light power generated by the light source but also the sensitivity of the human eye to different wavelengths of light. Light of different colors does not contribute equally to the total luminous flux due to variability in the sensitivity of the human eye across the visible spectrum; for example, the eye is more sensitive to green light than to red or blue light.
The maintenance of the luminous flux emitted by a luminaire is the evaluation of the long-term performance of LED light sources.
The degradation of the luminous capacity of LED luminaires, i.e. the gradual decrease in the amount of light emitted over time, is a phenomenon inherent to these devices.
The lifetime of an LED luminaire has been standardized in the industry to refer to the point at which the luminous capacity of the LED is reduced to 70% of its initial light output. This threshold, known as L70, has become an industry benchmark, providing a common framework for comparing the durability and luminous efficiency of LED products.
The specification of 50,000 hours until L70 is reached is indicative of extended life, suggesting that, under normal operating conditions, an LED luminaire can maintain a functional light output for a significant period before replacement or maintenance is required due to luminous degradation.
The importance of L90
While the L70 standard provides a basis for evaluating LED performance over time, some products on the market exceed this benchmark (backlink ?), exhibiting slower rates of luminous degradation.
These products reach the L90 threshold, which means that they retain 90% of their initial luminous capacity after a specified period, which is usually also 50,000 hours, although this may vary.
Some products even exceed L90, offering even lower degradation and thus higher retention of their luminous flux over time.
The selection of LED luminaires that exceed the L70 standard and achieve L90 or higher has significant implications from both a technical and economic perspective.
From a technical standpoint, a lower rate of luminous degradation ensures a more consistent quality of light over the life of the product. This is especially critical in applications where color uniformity and color accuracy are paramount.
In economic terms, although products that achieve L90 may represent a higher initial investment, the slower LED luminous flux decay means that their effective lifetime is longer, reducing the frequency with which they need to be replaced. This can result in significant savings in terms of maintenance and replacement costs over time.
Luminous flux maintenance is a determining factor in evaluating the long-term performance and economic sustainability of LED lighting solutions.
The standardization of L70 has provided a valuable yardstick for measuring luminous degradation, while the existence of products that achieve L90 or higher offers advanced options for applications requiring higher luminous flux retention and operational efficiency.
Careful selection of LED luminaires, taking into account their performance in terms of lumen maintenance, is essential to maximize the efficiency, sustainability and economic viability of long-term lighting projects.
Our focus is on exceeding established industry standards, such as L70, to deliver products that not only meet but exceed expectations for performance, efficiency and sustainability.
With a portfolio that includes options that achieve L90 or higher, we strive to ensure that each luminaire provides superior light quality, exceptional durability and reduced lumen maintenance over its lifetime.
