R. STAHL: LED Technology for Hazardous Areas

LED Technology for Hazardous Areas

Efficient, durable and robust

The paradigm change in lighting technology is in full swing – the future, including for industry, is in LED technology since no other lighting technology utilises the electrical energy input as efficiently and has a long service life.

Some people are delaying the changeover, but there is undoubtedly no better time than now.

Regardless of whether you want to save energy, reduce maintenance costs or benefit from a long-life luminaire – the changeover to LED technology is the way to achieve it.

The service life of LEDs alone – up to 100,000 hours – exceeds the values for conventional light sources by many times over. This increases the maintenance-free time exponentially. Particularly when combined with maintenance-free lighting designs, the operating and maintenance costs are negligible minimum.

High-performance diodes provide excellent luminous efficacy with up to 180 lm/W, the LED is nearly ten times as efficient as a normal halogen lamp. LED luminaires are also experts in saving energy. This means that the slightly higher procurement costs will be amortised after only a few years.

At the same time, reduced CO2 emissions will contribute to climate change protection and in addition, does not contain any mercury, which means that LEDs can be described as being environmentally friendly.

LED luminaires improve safety as they do not leave anyone abruptly standing in the dark. They lose their luminescence gradually and hence don't fail completely all of a sudden.

LED technology is ideal for use in extreme temperatures in particular because it boasts a high vibration resistance, which means that it is especially well suited to use in harsh industrial environments. It is also characterised by a low heat build-up and can therefore still be used at temperatures from -60 °C to 70 °C. In addition, luminous intensity can be controlled depending on the ambient brightness.

LED lighting compared to conventional lighting technology

LED luminaires have numerous benefits over conventional luminaires. We have compared them for you in the table below.

You can see that LED technology provides you with both tangible and intangible benefits. So do not delay any further and switch to LED – become part of the future.

Here you can find a list of frequently asked questions relating to LEDs

1. What are the benefits of LED compared to conventional luminaires?

    • Longer service life. This increases the maintenance-free time.
    • High-performance diodes provide excellent luminous efficacy.
    • LEDs are experts in saving energy.
    • Operating and maintenance costs are reduced to a minimum.
    • Lower CO2 emissions – LED luminaires are therefore contributing to climate protection.
    • Ideal for use at extreme temperatures.
    • LEDs stand out from other lights due to their high vibration resistance. They are therefore especially suitable for use in harsh industrial environments.
    • LED luminaires improve safety because instead of suddenly failing completely, they lose their luminosity gradually.
    • Luminous intensity can be controlled depending on the ambient brightness.

      2. What are the disadvantages of LED?

      LEDs are initially more expensive in terms of procurement costs, but ultimately the cost benefits of using modern LED technology prevail in the long-term. These benefits can be easily established via our TCO-/ROI-Rechner.

      3. Should we wait a little longer before using LED?

      No. LED technology is the most cost-effective and the most up-to-date lighting technology in the market. The long operating life ensures greatest cost benefits overall if you change over as early as possible. Quick decisions could largely save your maintenance costs as well.

      4. How advanced is the development of LED?

      The use of LEDs is no longer a topic of the future. The technology is now sophisticated enough that it can be used without restrictions. The luminous efficacy is significantly over 100 lm/W. The service life of R. STAHL's LEDs is more than 100,000 hours. This corresponds to continuous operation for over 10 years.

      5. Why are LED luminaires more expensive compared to conventional luminaires?

      The manufacturing of LEDs involves durable, high-quality materials that are impact resistant and heat resistant. Their production is also accompanied by higher manufacturing costs, which makes them more expensive than conventional luminaires. But this only applies to the procurement price. The slightly higher procurement costs will be quickly compensated by lower operating costs, thanks to electricity savings and lower maintenance costs. Therefore, if we take into account the entire service life, LEDs are more cost-effective.
