LED lamp vs incandescent light bulb
How does LED work?
LED stands for ‘Light emitting diode’ . A diode is an electrical component with two electrodes, which only allows electricity to pass freely in one direction. Through the constant movements of the electrons in the semiconductor, light is generated.
What are the advantages of LED?
- Low power consumption – Because it is not necessary to heat up a filament, the main advantage of LED bulbs is the energy efficiency. No energy is getting wasted and it is possible to save up to 80 %.
- Long lifetime – The average lifetime of LED lamp is about 35.000 to 50.000 hours. Incandescent bulbs on the contrary only 1000 hours. The longevity of the LED products leads to low replacement and energy costs, therefore a fast amortization time is usually guaranteed within one year.
- Environmentally friendly – In Contrary to traditional light bulbs, LED bulbs contain no toxic chemicals. For example, a broken energy saving bulb is not only harmful to your health (mercury vapor) but also to the environment. In addition, it is special waste, which cannot be easily disposed.
- Perfect for accent lighting – LED bulbs are available in a variety of color temperature and color displays. The light beam of a LED bulb is generally between 8 ° and 360 °. This has the advantage that a suitable LED bulb is available for every possible situation. This allows you to create specific accent lighting, but also to imitate the look and feel of a traditional light bulb.
What is the disadvantage of LED?
- High acquisition costs – The initial investment is higher than for incandescent bulbs. Due to the long life and high energy efficiency of LED bulbs, a fast ‘Return on Investment’ is possible.
How does an incandescent bulb work?
A conventional light bulb produces light through the filament in the low-oxygen glass bulb. As soon as the light bulb is connected to a voltage source, the filament is heated up so strongly that it generates light.
What is the advantage of an incandescent lamp?
- Low acquisition costs – The prices for traditional light bulbs are very low and are often already available for 1, - Euro.
- Perfect color rendering – Conventional light bulbs have a CRI of 100 and guarantee perfect, vibrant colors
What are the disadvantages of an incandescent bulb?
- High power consumption – Light bulbs have the worst energy efficiency of all types of lighting. 90 % of the energy, which is required to heat the filament of the bulb, is getting lost.
- Short lifetime – The lifetime of an incandescent bulb is an average of 1000 hours. This means that you will have to regularly replace your conventional bulbs.
Where were traditional light bulbs used?
Usual applications for incandescent light bulbs were as interior lighting for residential areas. They generally have not been used in companies due to short lifetime and poor energy efficiency.
