the essentials in brief

  • LED lamps allow you to flood your rooms or your outside area with warm white light, and with extremely low power consumption.
  • Basically one can differentiate between high and low voltage LED lamps. Which one you need largely depends on the intended use.
  • Low-voltage LEDs are usually cheaper to buy, and installation can be done without the risk of dangerous electric shocks. However, an external transformer is also required, which is why there is almost no difference in price between the two types.

Power consumption

The power consumption, which is measured in watts, is the largest and also the most important distinguishing feature of LED light bulbs to the conventional light bulb.

LED lamps have the highest energy efficiency. So, compared to their competitors, they convert the most energy into light. A 60 watt light bulb has a luminosity of approx. 600 lumens. A current LED lamp that generates 600 lumens, on the other hand, only consumes 8 W.

If a 60-watt light bulb burns 3 hours a day, it consumes 65.7 kWh a year. With an electricity price of € 0.26 per kWh, there would be annual electricity costs of € 17.08.

An LED lamp with 600 lm comparable to the luminosity, on the other hand, would only consume about 10 watts. The annual electricity consumption would be 10.95 kWh. The electricity costs would be 6 times smaller at € 2.85. The annual savings would be € 14.24. After 5 years it would be € 71.18.

lifespan

LEDs have a long but not an infinite lifetime. Basically, LEDs can have a lifespan of up to 100,000 hours, which is approximately 11.5 years.

Such a long service life is only possible under certain circumstances, namely that the values ​​specified by the manufacturer for operating current and temperature are observed. Of course, external circumstances such as moisture or weather conditions can also play a role.

Depending on the lamp, the lifespan of LEDs today fluctuates between 10,000 and 50,000 hours. In contrast to conventional light bulbs, an LED does not suddenly simply fail, but gradually loses its brightness over the course of its operating time. Depending on the quality of the light-emitting diode, this decrease in brightness (degradation) is sometimes faster or sometimes slower.

Light temperature

The light temperature describes the color impression that a light source has and is measured in Kelvin. Warm light color has a low Kelvin number, whereas cold light color has a high Kelvin number.

For example, a candle has a color temperature of 1,500 Kelvin, a 100 watt incandescent lamp 2,800 Kelvin, while the morning or evening sun has a temperature of 5,000 Kelvin. A suitable alternative name for the term color temperature is also "mood" or "ambience" which is important for buyers of LED lamps.

The common spectrum for LED lights ranges from around 2,700 Kelvin to 8,000 Kelvin. Higher values ​​of up to 10,000 Kelvin can be achieved, but have a very unnatural effect and are usually not used to illuminate rooms, but are used, for example, to illuminate aquariums or outdoors.

This color temperature comes very close to daylight when the sky is bright. A rough distinction is made between the following color temperatures:

  • 2,700 to 3,250 Kelvin: warm white
  • 3,250 to 5,250 Kelvin: neutral white
  • 5,250 to 8,000 Kelvin: daylight white

Beam angle

Beam angle is the angle at which the light is emitted to the front by a lamp. The distance between the LED lamp and the illuminating object plays an important role here, since the beam angle should be chosen to be large or small accordingly.

Basically, the larger the beam angle, the larger the diameter of the light cone.

But which beam angle do you need for which location? The larger the room, the larger you should also choose the beam angle of the LED lamp. On the other hand, if you want to shine a certain object (e.g. a picture) in the light, you should choose a smaller beam angle.

A beam angle of 120 ° is generally suitable for basic lighting in living rooms, and a beam angle of 90 ° is recommended for lighting path areas.

Light output

The light output indicates the brightness of a lamp. This is influenced by the number and quality of the diodes and the beam angle of the radiator.

Basically, lamps with a high beam angle (up to 360 °) illuminate a larger area, but have a lower light output than lamps with a lower beam angle (at the same power). The brightness is given in lumens per watt, so in this context it's about the light output.
