A Professional and Sustainable LED Solution
Upgrading LED luminaires with fixed modules does not always mean replacing the entire installation. In many projects, the key is to address factors such as frequent switching, compliance with energy efficiency regulations, preserving the original architectural design, or the need to reduce costs and waste without unnecessary construction.
In all these contexts, retrofit with LED modules emerges as the most efficient solution, as it extends the luminaire's lifespan, improves performance, and provides new control capabilities without altering the existing housing.
This strategy is especially valuable in staircases and corridors with presence sensors, in the rehabilitation of heritage buildings, in spaces where aesthetic design must remain intact, or in installations aiming to extend their lifecycle while reducing environmental impact.
In this article, we analyze the advantages of modernizing luminaires using LED modules, the technical requirements to consider, and the benefits they bring to manufacturers, architects, and designers in rehabilitation projects and energy efficiency improvements.
When is it better to upgrade rather than replace a complete luminaire?
These are the most common cases where LED module retrofitting is the best alternative:
– Housings in good condition: when the structure and diffuser maintain their integrity and IP protection rating. In such cases, upgrading with LED modules extends the luminaire's life without full replacement.
– Aesthetic or heritage design: in luminaires of architectural or historical value, LED retrofitting ensures efficiency and durability without altering the original design. It saves costs and preserves aesthetic and lighting heritage.
– Spaces with frequent switching: staircases, corridors, or areas with presence sensors are environments where conventional replacement lamps fail quickly. In these cases, AC LED modules stand out for their proven resistance to thousands of on/off cycles.
– Construction, time, or budget constraints: choosing to upgrade with LED modules avoids full replacements, enables significant savings in cost and installation, and allows rapid intervention without interrupting activity.
– Smart control integration: LED modules are compatible with systems such as DALI, Casambi, or D4i, enabling optimized consumption and preparing the installation for future regulatory requirements.
– Sustainability goals: upgrading luminaires instead of replacing them reduces waste, promotes a circular economy, and helps meet energy efficiency targets.

From Fluorescent to Professional LED Modules
An LED module is essentially the "light engine" of the luminaire. It is not just a replacement lamp, but an integrated part of the structure, giving it clear advantages over traditional solutions:
– Superior energy efficiency: delivers higher luminous efficacy (lm/W) with lower power consumption.
– Extended lifespan: up to 100,000 hours versus 10–15,000 hours for a fluorescent lamp.
– Stable color and intensity over time, without abrupt degradation.
– Instant and flicker-free start, even in presence sensor applications.
– Future-ready: easy integration with DALI, Casambi, and D4i.
– Design freedom: more compact, efficient, and aesthetically differentiated luminaires.
Additionally, Optoga AC LED modules operate directly from mains power, without external drivers. This simplifies integration and reduces potential failure points, especially in luminaires subject to frequent switching.
Extreme Resistance to Switching and High Temperatures in LED Luminaires
Staircases and other high-traffic areas (such as corridors, public restrooms, or parking lots) are especially demanding: switching can easily reach 100 cycles per day. Under these conditions, conventional replacement LED bulbs often fail within months, generating constant replacements — up to 24 per luminaire over 10 years — and high maintenance costs.
To meet this challenge, Optoga has subjected its AC LED modules to laboratory testing that certifies their durability, with remarkable results:
– Over 1,000,000 ON/OFF cycles at 25°C.
– 500,000 cycles at 85°C.
– Target lifespan of up to 100,000 hours, with stable color and luminous flux.
These results — based on specific tests and technical documentation — confirm that Optoga LED modules greatly outperform conventional replacement solutions, ensuring reliable and predictable operation in intensive-use applications.
Smart Control in LED Luminaires: DALI, Casambi, and D4i
Luminaire modernization not only improves today's efficiency: it also prepares each project for tomorrow's challenges. Thanks to LED modules, it is possible to integrate control systems like DALI, Casambi, or D4i, which provide key advantages such as:
– Precise and flexible dimming (schedules, presence, daylight).
– Optimized energy consumption.
– Real-time monitoring.
– Compliance with the EPBD (European Energy Performance of Buildings Directive).

Case Study: Luminaire Upgrade at the Swedish School of Textiles
At the Swedish School of Textiles, upgrading the lighting system was a matter of vision, not just efficiency. With Fagerhult Dome luminaires nearing the end of their lifespan, discarding functional parts was not an option. The challenge was clear: combine technological innovation and smart control without compromising the original design’s aesthetics, a key factor in a high-value architectural space.
The solution came through retrofit with AC LED Lilly80 modules (SEE DATASHEET)
They operate directly at 230 V with integrated DALI control, eliminating the need for external drivers.
They provide high-quality light and long lifespan, even in intensive-use applications.
They allow real-time smart supervision and adjustment, with information on status and energy consumption.
The result: luminaires that not only regained their lifespan but became an example of LED retrofitting in a heritage space. Sustainable, efficient, and future-ready lighting, thanks to technical collaboration and intelligent use of resources, while respecting the original design aesthetics, a key factor for architects and designers.

LED Retrofitting Process in Existing Luminaires
LED module retrofitting is not just a lamp swap: it is a controlled technical process ensuring the final luminaire meets all reliability, safety, and regulatory requirements.
It usually includes four key phases:
1. Initial audit: inspecting the housing, optics, and thermal dissipation capacity.
2. Module and control system selection: defining power, luminous flux, color temperature, and compatibility with control systems (DALI, Casambi, D4i).
3. Integration and validation: conducting thermal, electrical, photometric, and electromagnetic compatibility (EMC) tests.
4. Documentation and CE marking: updating the luminaire's technical file and issuing the relevant documentation.
Thus, LED retrofitting becomes a safe, sustainable, and guaranteed process, providing value to manufacturers, installers, and specifiers alike.
