Hoffmeister LED retrofit – upgrading existing luminaires

LED retrofitting – the sustainable path to modern lighting

The demands on lighting solutions are increasing: energy efficiency, sustainability, compliance with standards, and cost-effectiveness are now key criteria for businesses, municipalities and institutions. At the same time, many buildings still use functioning but outdated lighting systems – with high energy consumption and limited light quality.
The solution is retrofitting existing lighting with LEDs. This involves integrating energy-efficient LED technology into existing luminaires without the need for a complete replacement. This enables energy savings, significantly reduces maintenance costs, and sustainably improves lighting conditions.
Our LED retrofits for existing luminaires are precisely matched to various luminaire types and applications. They include all the necessary components for a quick and standards-compliant retrofit.
Upgrade to LED lighting now – economical, future-proof, and environmentally friendly.

Why LED retrofitting is essential:
Fluorescent tubes no longer available

Fluorescent tubes – such as T5 and T8 types – and other mercury-containing lamps can no longer be sold or placed on the market in the European Union. This is due to EU regulations on energy efficiency and the reduction of hazardous substances such as mercury. While existing luminaires can still be used, compatible replacement lamps are becoming increasingly scarce. Continued operation is therefore becoming technically and economically difficult – switching to LED technology is inevitable.

Hoffmeister follows a sustainable approach: the aim is not to replace entire luminaires, but to modernize existing systems selectively. With tailored LED retrofit kits, the existing luminaire housing is retained – only the outdated technology is replaced with energy-efficient LED components. This allows proven installations to continue in use and transition into the future in a resource-conscious way.

LED conversion with retrofits: replace the technology, keep the luminaire

LED retrofitting is a modern and economical renovation method for equipping existing luminaires with energy-efficient LED technology – without replacing the entire lighting system. Instead of installing new luminaires, only outdated components are replaced with LED-compatible parts. This reduces energy consumption, lowers maintenance costs, and extends the system’s lifespan.

Typical components of a retrofit:

Light sources: Replacement of fluorescent tubes, HQL, HQI, or halogen lamps with LED tubes, modules, or boards
Ballasts: Replacement of conventional magnetic or electronic ballasts with LED drivers
Wiring: Internal rewiring may be required, e.g., for T8 LED tubes

The advantage: The existing luminaire housing is retained. This saves material, minimizes conversion work, and reduces electronic waste.

Why is an LED retrofit worthwhile? Your benefits at a glance:

High energy efficiency: Up to 70% less power consumption
Cost reduction: Lower maintenance and operating costs thanks to the long lifespan of LED components
Environmental protection: Less CO₂ emissions through sustainable technology
Optimized light quality: Flicker-free, instant light with accurate color rendering
Quick implementation: Easy installation, usually without intervention in the building structure
Eligible for subsidies: Grants and programs available for commercial and municipal retrofits
Future-proof: Ensures long-term, efficient, and compliant operation of existing lighting systems

When is LED upgrading with retrofit kits particularly sensible?

An LED retrofit is ideal wherever existing luminaires are still functioning reliably, but no longer meet current requirements in terms of energy consumption, light quality, or maintenance. Retrofit use is especially cost-effective in buildings or facilities with long daily operating hours – such as in industry, administration, or public infrastructure.
Retrofitting is also a smart solution for special luminaires or customized lighting systems – especially when procuring a replacement for the original luminaire is not technically or economically feasible. In such cases, a retrofit allows the existing luminaire housing to be retained while only the internal technology is modernized.

Typical areas of application for LED retrofit solutions

Hoffmeister – Your Partner for Professional LED Retrofitting

At Hoffmeister, we combine decades of experience in luminaire development with innovative LED technology. As a manufacturer, we know exactly what matters when retrofitting existing luminaires – from technical feasibility to standards-compliant implementation.
Our retrofit solutions are developed in close collaboration with the needs of industry, municipalities, and planners. Each retrofit kit is precisely tailored to the specific luminaire model and guarantees a quick, safe, and efficient transition to modern LED technology.
To ensure maximum durability, our LED retrofits are made from high-quality die-cast aluminum – a material known for its strength, excellent heat dissipation, and resilience. This not only enhances efficiency but also significantly extends the service life of the entire luminaire.
Whether it’s a single installation or a large-scale project – we support you from selection to implementation.
Get in touch – we’ll find the right solution for your lighting system.
