What are LEDs?
What are LEDs actually? What are the advantages of LEDs? Why should you buy LED?
LED is a more recent technical development for generating light with the help of electricity. The main advantage of LEDs is that LEDs save significant amounts of energy compared to older technologies such as incandescent lamps or fluorescent lamps. This makes LEDs environmentally friendly and significantly reduces energy costs.
The name LED is an abbreviation for “light-emitting diode”, which means light-emitting diode or light-emitting diode. An LED essentially consists of a semiconductor crystal, as it is also used in microchips.
LEDs have been around since 1962, but due to their low power they were mostly only used for light displays and the light color blue could not yet be manufactured. It was only at the end of the 1990s that the field of application of LEDs expanded enormously. For the first time it was possible to build white LEDs thanks to the development of the blue light color.
The first areas of application were, for example, flashlights, which could be made smaller, brighter and more economical than their predecessors. Within a few years you could buy better and better light sources with LEDs.
Advantages of LED:
- Lower power consumption, compared to incandescent lamps, 80% energy can be saved
- less heat development
- shock resistance
- very long life
- no UV or IR component in the light
- small dimensions
- No heavy metals used, easier to dispose of and recycle
- lower costs and consumption in air-conditioned rooms
- 100% light immediately (no "warming up" necessary)
- Saving of maintenance work
- fully dimmable
Disadvantages of LED:
It would be dishonest to just list the many advantages of LED lighting here. LEDs also have disadvantages, but I think they can be avoided by choosing the right products.
That brings us to the main disadvantage: cheap products and market flooding.
In my parents' electrical shop, buying a light bulb was almost child's play: E27 or E14? Clear or matte? 60 or 100 watts? With just a few questions you knew exactly what you needed.
Nowadays, buying a light source is almost a torture, the shelves in the hardware stores almost collapse with so much selection. Many factors have to be taken into account that the same applies of course to other shapes when purchasing LED lighting.
Possible disadvantages would be, for example:
- flickering light
- poor color rendering
- poor efficiency
- too short service life
- higher acquisition costs
These disadvantages arise (apart from the price) but only in what I call "cheap junk", although unfortunately every second product seems to be affected by it!
Don't buy cheap NoName products! Buy in a specialist shop, such as here in our LED shop!
Hardware store products are very often optimized for particularly inexpensive production in order to achieve extreme profit margins on sale. The articles are then of course of inferior quality, as they are produced in Asia for very little money.
Our articles are probably a bit more expensive to buy, but with a 10-20 times longer service life, we probably offer the cheapest articles here!
In summary, I can think of no reasonable reason against LEDs, except perhaps the higher acquisition costs, which are always amortized through the energy savings, provided that high-quality and therefore long-lasting products are used!
