Energy saving lamps comparison 2018

Purchase advice for the energy-saving lamps comparison or test 2018

  • Energy saving bulbs have lower wattage than conventional light bulbs because they have a much lower power requirement to shine brightly. The EU has meanwhile banned the sale of light bulbs commercially.
  • Inside the energy saving lamp is a compressed mercury gas mixture. Due to the added current, the gas mixture reacts and is thus brought to light. The economy lamp is also called compact fluorescent lamp.
  • To ensure that the luminaires fit exactly into the base of your domestic lamp, there are the most energy-saving lamps with thin (E 14) and thick (E 27) sockets, which differ in their thread diameter.

1. Large design choice despite uniform structure: The structure of energy-saving lamps

Energy saving lamps comparison 2018: lamps

Energy-saving fluorescent lamps are now available in many different designs.

When the first energy-saving bulb with ballast from Osram was launched on the market in 1985, the energy-saving light bulbs were still recognizable by their unique shape. In most cases, the glass was not pear-shaped, as in conventional light bulbs, but tubular and curved in itself. Meanwhile, the appearance of compact bulbs is much more conventional and provides an offer for every taste.

Inside the energy saving lamp there is a gas mixture whose electrons are activated by the power supply. By an electro-chemical reaction, the components of the gas begin to glow. This requires much less energy than a wire in light bulbs needs to light up. In short: The energy saving bulb shines brightly and uses little energy.

The size Alternative to the energy saving lamp is the LED lampwhich provides brightness to light emitting (ie emitting) diodes. she is also very economicalbut is often under criticism because their light is perceived as unnatural.

The structure of the energy saving lamp is simply explained from bottom to top: The lamp base goes into the so-called starter of the energy saving lamp, which ensures the heating and activation of the mercury in the energy-saving lamp. Above it is the glass of the lamp.

Danger: Mercury is a toxic heavy metalthat you should never touch if the energy saving lamp is broken. Do not inhale the vapors either. If a light breaks, it is best to sweep up the mercury pellets with a hand brush and gloves Immediately ventilate the room for as long as possible for 15 minutesadvises the Federal Environment Agency.

You would like to touch the energy-saving lamp during operation in order to replace it? We do not recommend this to you for the sake of your health. Though The glass of the energy saving lamp is not quite as hot as that of a light bulbbut if the light shines for several hours and heats up, you could drop it in shock and break it. The leaking mercury does not want to breathe anyone in his household.

2. The Functioning of Energy-Saving Lamps: Hot Quick Start and Enduring Cold

Energy saving lamps comparison 2018: energy

Energy-saving lamps with G-mount are simply plugged.

The light source of the energy-saving lamps ensures that it takes a moment for the lights to reach their full intensity. Inside the small fluorescent tubes is a Mercury mixture, which is vaporized by the addition of heat and pressure.

These two factors must first be generated, which explains the wait for the full luminosity of energy saving lamps.

Due to the specific chemical reaction that causes the excited electrons to migrate, the visible light is generated.

Dispose of the energy saving lamp, if it is broken, in a box at the municipal recycling center. She definitely does not belong in the trash.

2.1. The quick-start energy-saving lamp reduces waiting times and gets up to speed quickly

Energy saving lamps comparison 2018: saving

Energy-saving lamps with quick-start function do not differ visually from other types of economy bulbs.

Around counteract the slow brightening of the compact fluorescent lamp, you can pay attention to a so-called quick start functionif you want to buy an energy-saving lamp. In this type of lamp, the heating of the gas mixture and the pressure on the gas mixture are built up immediately upon actuation of the light switch in high intensity. That's the lamp in seconds in the maximum light level.

Especially in corridors or basements, so often in transit zones, where your own stay is very limited, worth an energy-saving lamp with quick start. Note, however, that the extra "load" from starting to one faster wear of the compact fluorescent lamp leads. An additional warm start function indicates a short preheating of the gas mixture. So the lamp is "prepared" for it, that it will soon run at full speed.

How do you have the Advantages and disadvantages of an energy saving lamp with quick start summarized:

  • unfolds full luminosity immediately
  • No need to wait until rooms are light
  • lower life of the energy-saving lamps
  • higher purchase price than ordinary energy-saving bulbs

2.2. The cold-start energy-saving lamp is a long-lasting perennial burner

Energy saving lamps comparison 2018: 2018

In the bedroom you should take your time: The warm-up phase of a cold-start energy saving lamp is not negative here. A daylight energy saving lamp keeps you awake.

If a room is to be lit for a long time, you can reach for the energy-saving lamp without a warm start. The more moderate heating of the gas mixture takes longer, but the light is completely bright (some lamps even take several minutes to apply their full luminosity), but the durability of the energy-saving lamp is greater compared to the lamp with quick start.

The responsiveness of the electrons, which are responsible for the illumination of the mercury vapor, decreases with increasing duration of operation.
But do not worry: the average life of an energy-saving lamp is 10 times that of a regular light bulb.

3. Purchase criteria for energy-saving lamps: Note the following

3.1. Keep your composure! The pedestal and the lamps

The Edison Version

Energy saving lamps comparison 2018: comparison


The abbreviations of our most common lampholders are composed of the initial of Thomas Edison, ie "E" and the outer circumference of the lamp cap in millimeters, say 14 and 27 together. Abbreviated you will find as information on the lamp thread therefore E 14 and E 27.

What is the use of the best energy-saving bulb if it does not fit in your ceiling light? When buying compact fluorescent lamps, pay attention to the diameter of the thread on the light foot. In general, you only have to between thick (E 27) and thin (E 14) decide. Some fluorescent lamps still have a socket that reminds of a fluorescent tube.

The version with the declaration G 23 refers to a lamp which has an additionally installed starter for activating the luminosity of the energy-saving lamp. The obvious difference with the Edison versions: The G-sockets, such as the more frequently encountered forms of G9 and GU10 energy-saving lamps, are plugged in and not screwed.

3.2. The luminous flux in lumens

The so-called luminous flux is the best way to read the brightness of an energy-saving lamp. This indicates how high the light output of the luminaire is in reality.

The luminous flux is given in the unit of measure lumen (lm). Sometimes you will also find a manufacturer's indication, which refers to how high the number of lumens per recorded watt (lm / W) is.

The more lumens an energy-saving lamp has, the brighter it is. For bulbs, the wattage stands for the degree of brightness emitted. The higher the energy consumption, the higher the light output. In our table on energy-saving lamps and their equivalent bulb wattages, you can see how bright the lumens of the energy-saving lamp are.

light bulbEnergy saving lamplumen
25 watts6 watts230
40 watts9-10 watts430
60 watts13 - 14 watts730
100 watts21 - 22 watts1.380

3.3. Kelvin: Small color temperature customer

Normalized color temperature

The perceived light heat, that is, how comfortable the room ambience is through the lamp, can be estimated and even read. The unit of measurement Kelvin (K) is crucial for this. A 60-watt bulb has about 2,700 Kelvin, It is stated in DIN 5035 that a value of up to 3,300 Kelvin emits warm white light. Dimmable energy-saving lamps are not only variable in brightness, but also in the color temperature. If the energy saving lamp flickers when the lamp is switched on, it is not dimmable.

Tastes are known to be different. To equip a room with the right illuminant depends not only on your individual sense of comfort, but also on the location of the energy saving lamp. For example, a workshop does not need a romantic dinner light, but a neutral working atmosphere.

You can determine the evoked atmosphere of the light by selecting the color temperature of energy-saving lamps. The unit of measurement Kelvin (K) gives you information about how the emitted light of a compact fluorescent lamp is perceived by us. The higher the Kelvin value of an energy-saving lamp, the colder, ie more neutral, the color temperature is understood.

  • warm white light: <3,300 K (living room light, cozy)
  • neutral white light: <5,000 K (supermarket light, little noticeable)
  • cool white / daylight: > 5,000 K (work light, clinical)

3.4. A high energy efficiency class means high savings potential

Energy saving lamps comparison 2018: 2018

The energy label of the Osram energy-saving bulb Dulux Stick provides information on how economical the product is.

Although energy-saving lamps are by no means part of the major electrical appliances, they are awarded an energy-efficiency rating. The less watts an energy-saving lamp consumesto produce a certain brightness in lumens, the lower is their power consumption.

Even low-cost energy-saving lamps can have energy efficiency class A and are thus be a guarantor for a lower electricity bill, You save money and protect the environment with the purchase of an energy saving lamp.

If you doubt the durability of the energy-saving lamp and therefore would have to buy a new lamp more often, you can access a branded product from manufacturers like Osram, Paulmann or Philips.

4. Energy saving lamps in the test at test institutes such as Stiftung Warentest

The testing institute has not carried out an exclusive test of energy-saving lamps for a long time. Meanwhile, more and more LED lamps are used and testedthat have the great advantage of giving up the heavy metal mercury and even even a little more energy-efficient light as energy-saving lamps, Test winners among the LED lamps with E 27 socket were Bioledex energy-saving lamps with the overall rating VERY GOOD (1,3).

The same rating was obtained by the LED lamp from Vosla in the category of E 14 sockets. You can see the test results in test-issue 11/2016 in detail. If you are looking for an alternative, because you simply can not get used to the LED light, we recommend our comparative energy-saving lamp winner.
