Movements such as Fridays For Future have ensured that topics such as sustainability and environmental protection have now reached all sectors of society. Unlike previous waves of environmental activism, future-oriented action is no longer just about protecting the climate. Reducing greenhouse gases, conserving resources and avoiding waste are challenges that business and industry must face. The solution: A fundamental rethinking of industrial companies and the conversion to modern LED lighting systems are a first step in the right direction.

Why is a switch to sustainable lighting systems inevitable?


75 percent of lighting systems in European companies are more than 25 years old, far from a forward-looking lighting solution. Unfortunately for the environment, the majority of industrial, commercial and public spaces in Germany still rely on conventional lighting systems. The consequences of outdated systems are shown in a report by the International Energy Agency (IEA): in 2014, the share of lighting in global electricity consumption was 15 percent. Four-fifths of this alone is attributable to light in industry, trade and commerce, public authorities and transport. In addition, lighting accounts for almost five percent of global greenhouse gas emissions. The lighting industry needs a fundamental rethinking of the individual industrial companies in order to take the first steps towards a conversion to efficient and sustainable energy use. A modern, professionally planned and intelligently controlled lighting system guarantees that exactly the required amount of light is available at any place and at any time. Another advantage: Replacing an outdated lighting system with an environmentally friendly alternative not only reduces energy consumption and CO2 emission levels, but also ensures that unnecessary energy consumption is consistently avoided. Because despite a rising share of renewable energy applies: unused energy is still the best and cleanest “alternative energy source”.

From raw material to disposal: When is lighting really sustainable?


Not only the operation of a lighting system consumes valuable energy, also the production, the transport and the disposal contributes to an increased energy expenditure. Targeted analyzes of the life cycle illustrate how much primary energy is needed for each phase of a light source. Compared to conventional halogen lights, LED’s consume significantly less primary energy for the same light output, resulting in a much better eco-balance. HOLY TRINITY and Deutsche Lichtmiete® are young companies that take advantage of modern LED technology for future-oriented action. Because the lights are made unlike commercial products for long-term use in industry and retail, the quality must be secured even with continuous use. 

For example, HOLY TRINITY places value on high-quality materials that are exclusively processed by hand. In the event that one of the lights should fail despite a life expectancy of at least 50,000 hours, both companies guarantee an uncomplicated repair of the product. Damaged components are broken down into their individual parts and recycled to avoid environmentally harmful electronic waste. Sustainable action is also required for the final disposal of old lamps: According to the provisions of the German Electrical and Electronic Equipment Act, old lamps and fluorescent tubes must be disposed of in Germany in such a way that the raw materials they contain are not lost.
The Federal Environmental Agency now assumes that more than 93 percent of the waste lamps are recycled and so more than 90 percent of raw materials can be reused. Since LEDs can do without pollutants such as mercury – which is contained in small quantities in conventional fluorescent lamps – the recycling of LED lights is particularly environmentally friendly and possible without great effort. The certification of many manufacturers according to ISO 14000 illustrates the high standard of environmental protection, which is usually demanded by suppliers.

With an innovative rental concept, both HOLY TRINITY and Deutsche Lichtmiete® want to make the conversion to an energy-efficient lighting model for retail and industrial companies more attractive. ❝

Which sustainability trends can be identified?

New policies and technological advances have helped to reduce the enormous energy consumption in buildings in recent years. Today, just under seven percent of the energy consumed in buildings is due to lighting. Since 2000, the lighting efficiency improvements in the 34 member countries of the Organization for Economic Co-operation and Development (OECD) 1 have led to energy savings of more than 600 PJ. This corresponds to the equivalent of 160,000 gigawatt hours (GWh) and, according to the latest information from the IEA, is primarily due to the introduction and development of LED lamps. 2 Nevertheless, there is still a need for action: as many companies and industrial companies can not or will not afford the necessary investments for retrofitting, a large proportion of industrial and commercial space in Germany is still operated with conventional lighting systems – despite the demonstrably high energy efficiency of LED technology, With an innovative rental concept, both HOLY TRINITY and Deutsche Lichtmiete® want to make the conversion to an energy-efficient lighting model for retail and industrial companies more attractive. The rental model frees the customer from the considerable costs of a conversion; It only creates a fixed monthly rent, which covers all incidental maintenance costs for the lighting system at the same time. More than 400 refurbishment projects have now been successfully completed with the Light as a Service model of Deutsche Lichtmiete®. This shows that sustainable action is not only possible, but also provides economic incentives. What we need, then, is the realization that retrofitting alternative lighting systems is the only way to save our planet in the long term. We have to take action. And it now.
