The LED lamp is a modern illuminant and a future-proof light source due to its high efficiency and long service life. With its many possibilities in terms of colour, shape and luminous intensity, the LED lamp is establishing itself as the new lighting standard.

With our LED lamp test 2021 we want to give you the best possible advice and help you find the best LED lamp for you. In our test, we have compared simple LED lamps, LED ceiling lamps and LED filament lamps and listed their respective advantages and disadvantages.

The following information should make your choice easier and your purchase decision as simple as possible.




Summary

  • LED lamps are the most energy-efficient light sources on the market. Due to their high energy efficiency, up to 90% of electricity costs can be saved compared to incandescent bulbs.
  • The long life of LED lamps sets new standards. The minimum service life of 15000 hours clearly exceeds the service life of other light sources and is therefore particularly suitable for long-term use.
  • Due to the adjustable adjustment of the lighting conditions of an LED lamp, no wishes remain unfulfilled. LED lamps allow you to conveniently dim the brightness or switch between different colours.

The Best LED Lamp: Our Choices

Buying and evaluation criteria for LED lamp

In order to get an overview and make the right decision regarding your next LED lamp, you will find certain purchase and evaluation criteria below. The criteria selected to help you compare LED lamps with each other include:

In the following sections, we will describe these characteristics in more detail to show what is important when buying an LED lamp.

Power consumption

One of the most important questions to ask when buying an LED lamp is how much power it consumes. LED lamps are very energy efficient and the most power saving way to bring light into your home. They consume about only 14% of what an equivalent incandescent bulb would cost in electricity.

LED lamps emit the same amount of light but use 85-90% less electricity than incandescent bulbs.

For example, a 60-watt incandescent bulb can be compared to a 10-watt LED lamp. Since the luminosity of LED lamps is measured in lumens, this would correspond to a 600 lumen LED lamp. LED lamps thus have the highest luminous efficacy, which of course also becomes noticeable at the end of the year when considering electricity costs.

Assuming a burning time of six hours per day, using an LED lamp instead of an incandescent bulb saves around 28€ per year. In addition, there is a significantly more positive CO2 balance. All in all, the use of LED lamps produces the same quality of light, and you can also save some electricity costs in the long run.

Brightness and light colour

First of all, it should be noted that the light colour of an LED lamp is given in Kelvin. The colour temperature indicates whether a lamp has a warm or cool glow. Below you will find a short overview of how the Kelvin number influences the light colour of an LED lamp.

Kelvin number colour temperature
2700 to 3250 Kelvin warm white (cosy, homely)
3250 to 5250 Kelvin Neutral white (businesslike, positive)
5250 to 8000 Kelvin daylight white (higher blue content, cool)

Depending on your taste and needs, you should definitely pay attention to the different gradations when you next buy an LED lamp. Normally, warm white LED lamps are preferred in private rooms or restaurants. In contrast to offices, industrial halls or corridors, where neutral white to daylight white LED lamps are used.

Base type and lampholders

As is familiar from conventional light bulbs, the various LED lamp versions differ in their sockets. Therefore, before making a purchase, it is essential to make sure that the socket type of the LED lamp matches the socket to be used. There is a choice of screw sockets, bayonet sockets and plug-in sockets.

  1. The typical screw thread: which you know from standard light bulbs, is called E27 and stands out due to a very simple exchange. The size of such a thread is 27mm. Of course, there are also screw threads with a smaller diameter, for example 14mm, which are mainly used in chandeliers.
  2. Bayonet base: This type of LED lamp has two base pins and is inserted into the socket by plugging or turning. This type of LED lamp is usually found in wall lights, ceiling lights or hanging lights.
  3. Plug-in base: The designation for plug-in bases is G-24, which ultimately only differ in the number of their connection pins. These LED lamps are mostly used for shelf or shop lighting.

Service life

The service life of an LED lamp is usually given in hours, more rarely in years. Of course, the actual service life always depends on the individual use of the LED lamp. In general, the service life of LED lamps varies between 15000 - 100000 hours, which is considerably longer than that of incandescent bulbs or halogen lamps. You can find this information on the packaging.

The average life of an LED lamp is at least 15 times longer than that of an incandescent bulb.

If we assume an LED lamp with a service life of 50,000 hours and a weekly operation of 60 hours per week, the service life is approx. 16 years. However, the switching cycles also play a role. Especially with corridor or staircase lighting, the service life is reduced due to a higher number of switching cycles per day.

At the end of the service life of an LED lamp, however, they do not simply go out. They become darker and emit less brightness. To see how much brightness will still be available at the end of the life, you should look at the standard of the average rated life. With standard L80, you will have 80% of the original lumen value left at the end.

Beam angle

The choice of beam angle of an LED lamp is mainly related to the location and purpose. This is indicated by the unit degrees ° or by the abbreviation D (for degree).

The smaller the degree angle, the smaller the light beam of the LED lamp.

Theoretically, an LED lamp can achieve a beam angle of 10° - 360°. Very small beam angles are mainly used for illuminating individual objects or products. LED lamps with a beam angle of 90° are often found as basic lighting in narrow rooms and corridors or other pathways.

However, in order to find uniform lighting in normal rooms, you should buy LED lamps with a beam angle of at least 120°. For example, an LED lamp hanging at a height of 2.40 m with a beam angle of 120° illuminates an area 8.30 m in diameter.

Dimmability

First of all, it has to be said that not every LED lamp has the property of dimmability. However, every LED lamp that has this option is also labelled as such. This means that a particular advantage of LED lamps is that they can be adjusted to the desired luminosity at will.

Dimming an LED lamp means that you can individually adjust the brightness of the lamp according to your wishes.

A lower power supply reduces the brightness of the LED lamp. This is why this function also offers the additional possibility of saving electricity. To dim the LED lamp, you need a compatible LED dimmer.

However, more modern LED lamps already offer the function of being able to adjust the brightness digitally. In addition, there are also LED lamps that promise not only dimmability but also colour temperature control.

Decision: What types of LED lamp are there and which is the right one for me?

If you want to buy one or more LED lamps, there are two alternatives you can choose between:

Type Advantages Disadvantages
LED ceiling light brightness and colour adjustable, low power consumption higher initial costs
LED filament lamp all-round light (300°), retro look somewhat more expensive, greater risk of flicker

In the following sections, you can learn more about the different LED lamps.

LED Deckenleuchten

LED ceiling luminaires

Generally, ceiling lights serve as a central light source in a room to illuminate it evenly. Modern LED ceiling lights provide years of reliable, beautiful light while consuming only a small amount of electricity. Of course, there are various versions of these LED lamps, which differ in shape, design, brightness or even in the range of colours.

Advantages
  • low power consumption
  • colour adjustable by remote control or app
  • many different designs and shapes
Disadvantages
  • higher purchase costs
  • somewhat more complicated set-up

LED ceiling lights can be both simple and practical as well as round or square, so that they fit into any interior style. On the other hand, there are also more striking models consisting of individual LED lamps or captivating with their unique design and impressive details.

Most LED ceiling lights have an integrated colour temperature control that allows you to achieve perfect lighting conditions. With an associated remote control or a compatible mobile phone app, it is possible to conveniently dim the brightness and regulate the lighting conditions.

Some models are even equipped with a wider colour spectrum so that your rooms can shine in the most diverse colours. Despite this multitude of options and models, the price saving compared to ceiling lights with conventional light bulbs is enormous.

Although LED ceiling lights have higher initial costs, most LED lamps pay for themselves after only a few months due to their more efficient power consumption.

LED Fadenlampen

LED filament lamps

LED filament lamps are another type of LED light source. LED filaments are installed in a glass bulb similar to a light bulb. Filaments are narrow rod-shaped light-emitting elements inside a filament lamp.

The difference to conventional LED lamps with individual light-emitting diodes is that there are several strip-shaped filaments inside the LED lamp. As a result, you no longer see just a matt white light body, but yellow filaments, which have a cosier effect.

As with normal LED lamps, a colour temperature between cool white and warm white is possible.

Advantages
  • low power consumption
  • extraordinary design
  • creates a cosy atmosphere
  • light is emitted all around (300°)
Disadvantages
  • more expensive than normal LED lamps
  • higher risk of flicker
  • usually not dimmable

The unusual look of LED filament lamps means that they are mainly used in homes or restaurants. There, they spread a nostalgic and cosy atmosphere and create a retro atmosphere with their design. Due to this design, however, there is a higher risk that the filaments start to flicker unintentionally.

In addition, most LED filament lamps with their individual filaments are no longer dimmable and thus have a constant brightness level. However, they achieve a uniform beam angle of at least 300°.

Apart from the fact that both variants have a long service life and significantly lower power consumption than normal light bulbs, you should think carefully about the purpose of your LED lamp before buying it.

If you want an all-rounder that can provide you with different colours and lighting conditions, you should opt for a ceiling lamp. If you are looking for something special for your home and like the retro look, an LED filament lamp is probably the better alternative for you.

Guide: Frequently asked questions about LED lamps answered in detail

In the following guide, we would like to answer the most important questions about LED lamps. We will answer each question shortly and want to give you more essential tips and information about LED lamps.

For whom is an LED lamp suitable?

First of all, the question arises whether an LED lamp is suitable as a light source for every household or every company. This question can be answered easily. Because anyone who wants to save electricity costs and get something out of their lamps for a long time should switch to LED lamps.

On the one hand, LED lamps are suitable for private rooms and restaurants where warm white light is preferred. On the other hand, they are also a very good alternative for generating daylight and are thus ideal for workplaces and hall lighting. Thanks to their adjustable and dimmable lighting conditions, they are versatile in use.

In addition, LED lamps need to be replaced much less often than incandescent bulbs or halogen lamps because of their long service life. In the long run, this advantage offers you the possibility of not having to constantly worry about replacement and exchange of light sources.

What advantages does an LED lamp have over an incandescent bulb?

As already mentioned in the last question, you can save significantly more electricity with an LED lamp than with a standard light bulb. With the same brightness, an LED lamp consumes up to 90% less energy.

In addition, LED lamps are more environmentally friendly than incandescent bulbs because they last longer.

For example, you only need 12 - 16 watts for an LED lamp to replace a 100-watt incandescent bulb. Conventional light bulbs have a maximum life of 2000 hours. LED lamps, on the other hand, already have a minimum service life of 15,000 hours.

Another big advantage of LED lamps is their dimmability. No light bulb offers the possibility to adjust the lighting conditions in the room as desired. LED lamps, on the other hand, can be adjusted by dimmers, apps or remote controls as you wish. In addition, it is possible to let the LED lamp shine in bright colours.

Is an LED lamp suitable for outdoors or for the garden?

Just as your living or business rooms can shine with LED lamps, this is also possible outdoors and in your garden. Whether path lights, individual lamps or LED light chains. Everything is possible and gives you an atmospheric environment outside.

The majority of LED lamps for outdoor use have an IP44 protection rating. This indicates that these products are protected against splashing water from all directions. This means that ordinary rain will not damage the LED lamps.

However, if you want completely waterproof LED lamps, the designation IP65 should be present in the product description. As with LED lamps for indoor use, it is possible to adjust the brightness and the colour spectrum as desired.

Since the lamps are available in different colours and shapes, they can of course not only be used as outdoor lights but also as beautiful decoration in the garden.

What does an LED lamp cost?

There is a wide price range between the different LED lamps. Depending on the size, quality, functions and service life of the LED lamp, the costs can vary. The range for a simple LED bulb as well as for a LED filament lamp can be from about 4 euros to about 25 euros.

For a larger LED ceiling light, prices of 25 euros to 250 euros are normal. Of course, the price rises with increasing size and quality.

Type Price range
LED bulb/ LED filament lamp approx. 4-25 €
LED ceiling light approx. 25-250 €

If you compare these prices with normal light bulbs, you will notice a price difference that is to the advantage of the light bulb. Because yes, LED lamps are more expensive to buy, but much cheaper to operate.

Modern LED technology drastically reduces the power consumption and extends the service life. This is why the somewhat higher purchase costs will pay off after just a few months.

What alternatives are there to LED lamp?

Of course, there are other alternatives as well. We will take a closer look at these in the following table to give you a brief overview. Of course, we will also mention various advantages and disadvantages.

Type Description
Incandescent bulb Incandescent bulbs are probably the best-known way of providing suitable lighting conditions. Low purchase price, but associated with a shorter service life and higher electricity costs.
Halogen lamp Halogen lamps are somewhat more energy-efficient than incandescent bulbs. They are often used for spotlights or reading lamps.
Energy-saving lamp Energy-saving lamps save a considerable amount of electricity compared to incandescent bulbs and have a longer life. Compared to an LED lamp, however, it cannot hold a candle to the latter.

As can be seen in the table, the LED lamp is superior to the other light sources in many criteria and is the best choice in most cases.
