Filament bulbs: once the only light bulb for every area of use.

Choose the right socket for the right fitting, E27 or E14, have a quick look at the power consumption in Watts, screw into the fitting and switch on - changing the bulb was so easy in the days of the filament bulb. There was also no alternative: you had to live and work with what filament bulbs had to offer in terms of light quality. You got used to the warm white light colour, which is very useful for the living room due to its cosy atmosphere. You also had to get used to the very low level of energy efficiency. If an E27 bulb used 40 W of power, it could produce around 400 Lumen. This equals a light yield of just 10 Lumen per Watt. 95% of the energy was converted not into light, but heat. The low durability (just 1000 operational hours) of the bulb, commonly known as a filament bulb, did its best to make this bulb unattractive from a financial and environmental point of view. That is why a ban on filament bulbs, drawn up by the EU Commission, came into force on 1 September 2009. As a result, the filament bulb was gradually done away withby 2012 in four stages. More information on the removal of this bulb from the market can be found in our glossary under the phrase ‘filament bulb ban’.

No alternative, no ban: the modern alternatives to filament bulbs

Alternatives to the beloved filament bulbs were faced with the task of asserting themselves. This was not easy in the early days, which is why so many people used halogen bulbs, which are not dissimilar in terms of lighting technology, and are still used today due to their very good colour rendering. Even though higher energy efficiency along with large savings was attractive and a longer service life and less need to change the bulb was guaranteed, the first energy-saving light bulbs were not received all that positively. The spiral-shaped design of the energy-saving bulb was too different from that of the filament bulb. In addition, the light colour was, at first glance, not as warm as in filament bulbs. There was also the less convincing colour rendering. But the light bulb industry reacted quickly and created bulbs which shone warm white light and which won customers round with a higher colour rendering. To ensure that filament bulbs weren't missed too much, new lamps with a decorative surrounding bulb were produced. This was matte and hid the spiral of the energy saving bulb excellently. Now, energy-saving bulbs have become completely accepted as an alternative to the filament bulb and, with just a few bullet points in our guidebook area, we will show you just how easily you can avoid the much talked-about mercury content.

The LED - a top replacement for filament bulbs

The LED bulb has become the perfect replacement for filament bulbs, even more so than the energy-saving bulb. To explain this, it is worth comparing the key values involved in evaluating a light bulb. The lifetime of an LED bulb is 50,000 hours, but only 1,000 hours for a filament bulb. The light output for LED bulbs is up to about 100 Lumen per Watt, but only about 10 Lumen per Watt for filament bulbs. The light colour of the filament bulb is in warm white, in LEDs, all three colours - warm white, universal white and daylight - are represented. The colour rendering of the filament bulb is 100% - for LEDs, as of 2014, this is around 80%, which produces very good results for indoor and outdoor lights. Finally, the LED bulb is today available for every known fitting from E27 through to E14 up to G9 and GU10 - and with a design which imitates the original bulb. That means that even clear bulbs, such as a filament bulb, are reproduced for LED lamps.

Where filament bulbs meet their limits.

Filament bulbs have two other disadvantages which can be compensated by LEDs. Even if the light is convincing, the filament bulb itself needs a certain amount of space on or in the light. LEDs, on the other hand, are so compact that modern designers can implement almost any design for their lights. Even in modern indoor and outdoor lighting, the LED is used, in a comparatively concealed manner, to produce attractive light. The most up-to-date LED technology is regularly used in the high-quality products from our own brand - Have a look here at the extensive range of lamps and lights from The second situation in which filament bulbs quickly reach their limits is where a light is switched on and off frequently, for example in combination with motion sensors outdoors. Frequently switching filament bulbs on and off causes them to fail prematurely - long before their 1000 hours of operational time. LEDs, on the other hand, have high a switching capacity meaning that they are ideally suited for use with motion detectors. In addition, LED bulbs, like filament bulbs, shine with maximum brightness immediately. An energy-saving bulb needs a certain amount of switch-on time, which often makes using them in conjunction with motion detectors difficult.

Filament bulbs and LED bulbs from the best brands and manufacturers

As well as our own brand,, which has also increased activities in the field of high-quality LED light bulbs, more of our manufacturers are particularly prominent and successful. Among these is Osram, whose logo you must surely have seen once or twice on the packaging of your bulbs. Osram is now a sought-after manufacturer in the field of LEDs - the many years of experience of producing ideal lighting is their basis for this. Another producer of high-quality bulbs is Philips, which has rightly made a name for itself thanks to high-quality bulbs and modern lights. The efficient uptake of energy and the highest possible brightness achieved from this - in short, the energy efficiency - is the criteria by which you should to choose your replacement for filament bulbs in future.

Long-known and widely used: the incandescent bulb (filament bulb)

The filament bulb (incandescent bulb) has, until now, been the most widely-used light bulb. Filament bulbs (incandescent bulbs) are known for their warm, cosy light and good colour rendering. Incandescent bulbs can be used in all living areas and for all purposes from romantic, atmospheric lighting, to daylight-bright work room lighting.

Despite all their advantages, filament bulbs (incandescent bulbs) are unfortunately considered thermal radiators and are real energy wasters. The bulb converts only 5% of the energy used into light. The remaining 95% is converted into heat energy and disappears unused. That is why a ban on filament bulbs, drawn up by the EU Commission, came into force on 1 September 2009.

The filament bulb was then gradually done away with by 2012 in four stages. More information on the removal of this bulb from the market can be found in our glossary under the phrase ‘filament bulb ban’.

At the same time, the development of alternatives to the filament bulb is still on-going. In the future, filament bulbs will be replaced by halogen bulbs, energy-saving bulbs or LED bulbs with a screw socket.
