Questions about LED

What is LED and how does LED work?

LED (Light Emitting Diode) was invented already in the early 20th century, shortly after Edison invented light bulbs. At the time, few saw their potential, and it was only in the 1960s that the first red diodes were put to use and only as recently as the 21st century did the technology see wide use as a light source.

Unlike other light sources, LEDs contain no filament, gas, glass bulb or moving parts. LEDs contain a special semiconductor that emits light when current is passed through the diode.

Depending on the chemical elements included in the semiconductor, it glows with different colours; red, green, yellow, ultraviolet, blue. To protect against damage and to be able to be electrically connected, the diode is placed in a housing that gives an angle of radiation of 140-180 degrees.

Why are LEDs so expensive?

LEDs are more expensive to manufacture than traditional light sources such as incandescent lamps (which today are to some extent prohibited), hence the more expensive purchase price.

However, if you look at the lifespan and energy consumption of LEDs compared to traditional light sources, investing in LEDs usually pays off quickly. LEDs can save up to 85% of energy consumption compared to incandescent light sources while having a 4-40 times as long lifespan.

Are LEDs environmentally friendly?

Yes, unlike many low energy lamps, LED lamps contain no mercury and the manufacturing process has little impact on the environment.

But above all, the LED lamp is environmentally friendly as it consumes considerably less energy when used compared to, for example, "traditional" incandescent lamps. Energy savings can be up to 85%, which is good for both the environment and your electricity bill.

I want warm lights in my light fixture, is that possible with LED?

Since LEDs began to be used as a light source in the early 2000s, a lot has happened on the market. Back then, LEDs were perceived as cold light, but today it is possible to choose according to your own taste.

We offer both cold and warm light sources, what you should look at is what colour temperature the light source has. Colour temperature is measured in Kelvin (K), 2000K corresponds to the colour temperature of a candle and the higher the value the colder the light becomes.

Many of our light sources come in the colours amber and transparent, where amber has the lower kelvin and is therefore perceived as warm glow.

Is it true that LED lighting can interfere with other electronics in your home?

Yes, that is true, but only if the electronics included in the light source does not have proper Interference suppression. This is especially common for dimmable LED light sources as they also contain control electronics that require extra suppression.

If the requirements set by regulations and standards for CE marking are met, however, there should be no problems. All of our products are tested to meet the requirements of so-called electromechanical compatibility (EMC) to ensure that they do not cause interference on the mains or radio interference.

Good interference suppression is expensive and takes up space, which can be good to keep in mind when comparing different brands.
