Lighting is the low hanging fruit for energy saving
Professional lighting refurbishments in industry
A glance up to the ceiling certainly pays. Older lighting systems not only consume unnecessary amounts of energy and have high maintenance, they also no longer comply to standards and therefore pose a risk to work safety. Upgrading to LED offers many advantages: Improvements in efficiency, cost savings, long maintenance intervals and better quality of light, to name a few.
But in addition to economic selection criteria, further parameters must also be considered in industrial environments. Depending on the application, luminaires frequently have to withstand extreme conditions, e.g. high levels of dust, heat, cold, humidity and vibrations – and do so reliably, over many years of continuous operation.

Identify your savings potential!
1. Is your lighting system older than 10 years?
Older lighting installations consume unnecessary amounts of electricity. They are technically obsolete, incur high maintenance costs, are inefficient and no longer comply with current lighting standards. The resultingly poor lighting conditions reduce productivity and are a danger to work safety.
2. Is your lighting continuously switched on?
Using a light management system allows you to tap additional energy saving potential that in many cases is more than 50%. In addition to the economic and ecological benefits, electronically controlling a lighting system provides maximum operating convenience. As well as daylight control, making the most of motion sensors is recommended mainly in warehouses and storage facilities. Light is then only used when actually needed. This in turn effectively avoids the continuous and usually unnecessary consumption of energy.
3. Would you like to know whether refurbishing your lighting is profitable for you?
The older the lighting system, the more it pays to replace with modern LED luminaires. Significant cuts in energy costs for example compared to conventional technology result in significantly shortened payback periods.

Retrofit
LED retrofits – are they truly a good
There is still a widespread opinion that a lighting system can be inexpensively converted to LED technology just by replacing the conventional fluorescent lamps with LED retrofit lamps. However there are good reasons why a simple exchange of lamps won’t bring the desired result, and why a LED lighting system is the recommended solution.
Danger of confusion
There are some fundamental points which must be taken into consideration when selecting LED retrofit light sources. Some LED retrofits are especially designed for operation in luminaires with inductive control gear and others for use in luminaires with electronic control gear. It's not always clear at first glance which type of control gear is installed in the luminaire – they don't bear any unique identification. A qualified electrician’s expertise is required here, someone who is familiar with all the technical requirements of the specific system. In general, retrofitting work on a lighting installation may only be carried out by such experts.
Different light distribution
LED retrofits frequently generate light which is primarily indirect, whereas fluorescent lamps produce a uniform light distribution in all directions of emission. The consequence can be that the lighting effect in the room is completely different, since optical systems such as louvres or reflectors largely lose their function. Photometric values specified by applicable standards and hitherto realised by the existing lighting installations can be lost when LED retrofits are used. The LED retrofit’s entirely different functional principle can also affect photometric quality criteria such as illuminance, uniformity, glare restriction, energy efficiency, light colour, colour rendering, luminance distribution in the room, and life-cycle or thermo-management.
Technical safety
For safety reasons, exchanging a fluorescent light with a LED retrofit should be given careful consideration, since a simple exchange results in a non-intended use of the luminaire, whereby a quality mark (VDE or ENEC mark) loses its validity. Hazards which might develop due to an electric, electromagnetic, mechanical or thermal incompatibility are henceforth the responsibility of the user.
