FAQs About Replacing Lighting System with LED Fixtures
For Which Types of Companies Switching to LED Is Worthwhile?
Economically speaking, there are two main arguments in favor of LEDs: they have a much longer life span, and they consume much less electricity than other lamps. We recommend a changeover especially for all companies in which:
- The lamps keep operating for long hours every day.
- The current lighting system is older than 10 years.
- The electricity costs for lighting are very high and account for a high proportion of primary energy requirements.
How Much Power Do LED Lights Ever Save?
By switching to LED lighting fixtures, you can save an average of at least 55%. The exact rate depends, of course, on which lamps you have used so far in your company. For example, for mercury vapor lamps – the so-called HQL lamps – you can expect a savings potential of more than 70%. Many industrial companies will have to replace these lamps, which are still frequently used, in the near future. Since 2016, HQL luminaires can no longer be produced, imported or sold in the EU. As before the incandescent bulb, the inefficient HQL luminaires are to disappear from the market in favor of energy-efficient lighting solutions such as LEDs.
How Long Will It Take to Get Return with LED Replacement
This depends primarily on the above criteria: the operating time of the lights, the current lighting system and the amount of your electricity costs. Let’s take an example: in a company, operating times of 4000 hours per year are achieved, the electricity price is 17 ct / kWh, and classical fluorescent tubes with low-loss ballasts (VVG) are in use. In this case, amortization is expected approximately in 2 years.
Are Companies Switching to LEDs Just for Economic Reasons?
In most companies, the real savings and the short amortization time are the decisive factors for LED technology. However, some industrial companies are now also changing to LED because the prohibition of the HQL lights. Another significant feature of LED lamps is also their long lifetime – high costs for the maintenance of the plant are therefore a thing of the past. One of our customers is a logistician who once told me that the maintenance of his lighting system cost him around 80,000 Euros per year. If a luminaire fails, he had to order a stepper each time because of the high hall ceilings. For security reasons, the contracted company always sent two employees, who mutually secured each other. You can imagine that the long life of the light-emitting diodes in such cases will save a lot of money.
Can LEDs Replace All Conventional Lamps? Are They, For Example, Bright Enough for All Applications?
Yes, absolutely. The LED technology has now advanced so far that its light output is considerably higher than that of the conventional light sources with the same power consumption (watts). Also the prejudice that LED would spread cold uncomfortable light, has long been disproved. Today, LED lamps can produce all the light colors you are accustomed to from conventional lighting. They can therefore be used for any applications.
The light-emitting diodes are ideal for office workplaces because they provide a lot of brightness and thus have a positive effect on the motivation of the employees. Whoever is looking for a solution for the highest lighting requirements is also well advised with LED illuminants – for example, for professional lighting of sales areas or laboratory workstations.
Will LEDs Gradually Become Darker And Then Fall Out Completely?
Another notable feature of LED lamps is they do not fail all of sudden like conventional light bulbs. Its illuminance gradually decreases after a long life. In general, LEDs have a lifetime of 50,000 hours, which is 30 times more than other conventional lamps. But even after this enormously long life, LED lamps do not go out suddenly. Pay attention to the manufacturer’s data for the lifetime. For example, you can see a high-quality luminaire on the L90 B10 print. This means that after 50,000 hours, the LED light still needs to deliver 90% of its light output.
