What is an LED sign
Do you need orientation when buying lamps? Then you should definitely read on, because in this article we will show you where on the packaging you can find all the information you need. E.g. how brightly a lamp shines, whether it can be dimmed or how high its energy consumption is. We also want to take a closer look at some of the most common test marks.
You can find this information on the packaging
Since September 1, 2013, precise rules apply to LED lamps and illuminants Environmental friendliness, quality and labeling. Some other parts of the regulation, such as B. Regulation No. 874/2012 / EU for electric lights came into effect on March 1, 2014. Overall, the EU wants to make it easier for consumers to choose a lamp.
The following information is mandatory according to the EU regulation:
- Lumen indication: indicates the light output or the brightness of the lamp.
- Color temperature in Kelvin: indicates the light color, i.e. whether the light is warm white, neutral or cool white: the higher the numerical value, the cooler the light color.
- Socket type: Since there are also different bases for LED lamps, the type is shown on the packaging, here E27 - a screw thread with a diameter of 27 millimeters. So it is an LED retrofit.
- Dimensions: Length and diameter of the lamp in millimeters. Attention: Not every lamp fits into every light. It is best to measure beforehand.
- Lifespan: Approximate shelf life in hours or years. The longer the lamp should burn every day, the more important a long service life is.
- Dimmability: The symbol shows whether the lamp is dimmable or not.
- Energy efficiency class: Using the EU energy label, you can see which energy efficiency class the lamp is assigned to.
- Switching strength: this is how many switching operations the lamp can withstand.
- Start behavior: The start-up time specifies the period of time that the light source needs to reach 60% of its specified brightness.
- Colour reproduction: The abbreviation RA stands for the naturalness of color rendering. The higher the value, the better it is. In general, the following guide values apply:
→ 60-80 = moderate (outdoor area)
→ 80-90 = good (living room, office)
→ 90-100 = very good (graphics workstations, living room)
- Power consumption / energy consumption in watts:
indicates how much energy the lamp needs to operate. The optional comparison value printed next to it shows which light bulb this power would correspond to - rounded to 1 watt (here in the example of a 60 watt bulb).
- Disposal advice: Here you can find out how to dispose of it correctly - household waste or collection point. Incidentally, LEDs NEVER belong in the household waste, they are 90% recycled.
Is the Luminous flux not possible or only possible with a certain type of control, a separate note is required. That is also the case when the lamp is not taking for operation Standard conditions is optimized. You may also find information on the packaging on the Mercury content and a website address with further information.
Which properties are important depends primarily on the intended use
Just as there are big differences with the lamps themselves, not every property is equally important for every end user. Therefore, do not just blindly pay attention to the figures, but think about what is particularly important to you personally before buying. Imagine e.g. B. the following questions:
- Where should the lamp go? In the living room we recommend z. B. warm white, daylight white in the work area and in the hallway, high switching resistance is particularly important.
- Should the lamp be dimmable? This is possible with halogen lamps as well as some compact fluorescent and LED lamps.
- Does the lamp burn a lot and for a long time? Then you should pay particular attention to the service life and watt consumption.
If you take everything into account, you will certainly not be disappointed. By the way: If you have any questions about the right LED selection, why not use ours Chat or visit us Facebookand get advice free of charge.
