What is LED

 

LED stands for light-emitting diode and works by a rectifier diode and a transducer converting electrical energy into a narrow wavelength range.

 

Benefits of LED

LED uses less energy than a corresponding incandescent or halogen bulb that emits the same amount of light energy. This is partly due to the fact that incandescent or halogen bulbs also emit infrared light, which cannot be seen with the eye, but it can be felt in terms of heat. However, this does not emit LED, since LED only converts the light energy into visible light.

 

-LED savings

LED uses about 1 tenth of the energy corresponding to an incandescent or halogen bulb. This will of course be reflected in your electricity bill. You can calculate your energy savings or consumption on the Energy Agency's page on energy. https://sparenergi.dk/erhverv/vaaerktoejer/skift-til-led. You are also welcome to contact us regarding energy optimization questions regarding LED lighting.

 

LED lifetime

With LED, you typically get quite an extended life, compared to old-fashioned bulbs, such as incandescent or halogen bulbs. An ordinary. Bulb has a life of between 1000 - 3000 hours. An LED bulb has a service life of 30-50,000 hours, and LED fixtures can have a service life of 70,000 hours. LED chip tests show that they can have a lifetime of about 20 years. However, there are several factors that reduce service life, such as wind and weather, heat and cold, and the technical components such as the transformer. Therefore, we can provide a 2-year warranty on our LED bulbs and 5 - 7 years on our LED luminaires, which we hope, however, have a lifetime longer than this.

 

What to look for when buying an LED bulb

- Socket

It is essential to know the socket of the bulb you are looking for. There are lots of sockets and you can only use the bulb with the right socket unless you buy an adapter for the socket. You can find our range of socket adapters by following this link: https://www.gmienergy.dk/tilbehor. The typical sockets found with regard to the LED bulb are the socket types E14 or E27 and spot either Mr16 or Gu10, however this may vary. But keep in mind the type of socket before buying a bulb.

 

- Tint (Kelvin / K)

Kelvin also known as K, is a very important factor when shopping for LED bulb, it is the hue. The choice of tint depends on the use of the Led bulb. First of all, you can read Kelvin by the higher the number the whiter the light and the lower the warmer the light. Warm white and white, differentiate roughly between the 3000 and 4000K. To the general for private use we recommend 2700 - 3000 K, this is still a warm white color but not so hot as to get too sleepy to look at. As a cozy lighting you are typically down to 2200 - 2400 K in your LED bulb, this is warm, cozy and sleepy light, and was typically what you had in your old-fashioned Edison bulb. If you need to use the LED for the office you need to go up a bit, here we recommend 4000K if you work more efficiently in colder light.

 

- Volt (V)

Volt, also known as V, is the unit of measurement for electrical voltage. In Denmark and the rest of Europe we have 230V. Typically, the back of an LED bulb will stand 220-240V, and it can therefore be connected to the ordinary. power grid. Normally the LED uses a different Volt and therefore you need a transformer between the LED and the mains to convert the Volt, but in most cases the transformer is down in the LED bulb's own socket and it can therefore easily be used on existing old sockets. . YOU MUST KEEP EYING ON THE VOLTAGE: You will typically find it at the back of the box, and you may risk it from the LED bulb, spot, strip or other eg using 24V or 12V and these can be either DC (DC) or AC (AC). For example, if the package is 12V DC, then you must have a transformer between your power grid and your LED product with the designation (ie 12V DC).

 

- Flickerfree

Flicker and Flickerfree. Flicker is often found on cheap LED bulbs. Due to the frequency of the LED bulb, the LED bulb may have flicker, which means it is flashing. Blinking is usually not visible to the naked eye, but it can have health consequences such as severe migraine. However, this can be solved and if the bulb does not have "flicker", it will say that it is "flicker free". You should therefore always keep an eye on this, and typically if there is nothing on the package, the LED product has it.

 

- Lumen (LM) and Lux

LM is a typical way to measure the brightness of a bulb. Eg. an old-fashioned bulb of 100W will light up with approx. 1500Lm. When you then see a 1500lm LED bulb (Typically 10-14W LED) it will light up similarly. Figures between LM and Lux ​​are the same, but the concepts explain how they work in practice: Lumen is the total amount of light in 360 ° whereas LUX is the amount of light at one particular point, eg a desk. Lm you see at the back of the packaging of your LED product and Lux ​​you will. look at a light calculation of a room

 

- Color rendering (Ra / CRI)

indicates how well the colors can be reproduced by the light source. The sun can reproduce all colors 100% and therefore has Ra value 100. An old-fashioned incandescent bulb is quite effective if it has a Ra value of 97-99. Savings bulbs are typically on Ra 70-80 and halogen bulbs on Ra 92-95. We only produce LEDs with a Ra over 90, which is also what we recommend. Today it is possible to make LED with a Ra of about 97, but we have found that the brightness decreases per day. The higher a color rendering there is. That's why we balance our LED bulb between a high color rendering and a high strength (Lm) per day. W.

 

- SDCM (MacAdam)

MacAdam indicates the scatter in the light color. Color deviations are indicated by MacAdam ellipses SDCM (Standard Deviation of Color Matching), and determine how large the variation is on the LEDs used in a given light source. SDCM ranges from 1-10, and the lower the number, the less color variation one will experience. Having a low SDCM is preferred. Typically with LED lamps you can have an SDCM of 3 and European LED bulbs have an SDCM of 6. However, we have developed on our HC LED bulbs and are therefore able to have an SDCM of 4. You will find our bulbs under the link : https://www.gmienergy.dk/ledpaere.

 

- Dimmable

Some LEDs are very suitable for dimming. But not all dimmable LED works with your current light bulb for incandescent and halogen bulbs. It typically requires an LED compatible dimmer adapted to the much lower power consumption and electronics of the LED.

 

- LM DEPR.

is the luminous flux lost over time, and thus the complement of lumen maintenance. We typically use the term LM DEPR. On LED to tell how long the bulb can have the same brightness as when you first used your LED.
