What are my cost savings with LED tubes?

With an LED retrofit, you can see at a glance what you are saving. Three values are decisive here: number of lamps to be replaced, average electricity price and average burning time of the lamps. GLT thus creates a meaningful profitability calculation. This includes profitability, energy and CO2 savings as well as savings in maintenance costs.

Of course, we guarantee the required illuminance and healthy light without flickering. The agreed guarantees and all certifications refer to the complete system, i.e. to the conversion as well as to the tubes.

Elaborate and expensive lighting planning by professionals is superfluous with LED retrofits, as the lighting infrastructure is retained with high-quality LED light.

Why are GLT Tubes made in Germany?

The market for LED retrofit lamps is huge: Various companies offer numerous lamps that differ greatly in terms of quality and price. Because of this, it's important to compare products and pay attention to the fine print. Above all, find out about the probability of failure of the light source, the specified service life and the actual energy consumption - because cheap is not cheap in the long term.

German LED Tech has specially developed high-quality and durable LED tubeshigh-quality and durable LED tubes for G5 and G13 sockets for LED retrofits, which guarantee healthy light without flickering. They are made of aluminum, are 100% unbreakable, have a high-performance power supply and special heat management.

They are produced in Germany and are 90% recyclable. They are ENEC-certified according to EN 62776 and demonstrably exceed all reference values for eco-design and circular economy required by the EU. This means they can claim the title "best technology available on the market" for themselves. The risk of failure of the GLT TUBE over the minimum service life of 50,000 hours is less than 1%.

Can I continue to use existing ceiling mounts?

Why rip everything from the ceiling if the lights are still worth preserving and are state of the art? The aim of retrofitting is to retain and upgrade as many parts of the existing, standardized lighting infrastructure as possible. Only defective parts will be replaced. Experienced electricians upgrade the existing lighting infrastructure by removing sources of error, such as failure-prone ballasts.
