Myths about LED lamps Contemporary consumers are keeping up with the times and taking an interest in new technologies and products on the lighting market. Among the popular benefits of civilisation – energy-efficient light emitting diode lamps or so called LED-light sources, which are replacing the incandescent lamps in residential and administrative buildings everywhere. We do not stop repeating our argument on the advantages of LED-bulbs in comparison with the obsolete "Ilyich lamps": they permit the consumption of electricity to be cut by 85%, have a long service life and are less affected by voltage surges. However, consumers frequently counter the aforementioned positive characteristics by arguing that there are negatives: light emitting diodes emit "cold" light, their power is low, which affects brightness, they are incompatible with regular sockets and are expensive. Let us check whether these negative characteristics actually exist, or if they are just myths.
Myth No. 1. LED-bulbs emit only cold light
Not everyone pays attention to the colour temperature of the light emitting diode lamp, which is measured in Kelvins (K), upon the purchase of the lamp. LED-sources emit both cold (4500-6000 К), as well as warm (2200-3000 К) and even neutral (3000-4500 К) light. Conscientious manufacturers always indicate this information on the package. Thus, in comparison with incandescent light bulbs, light emitting diodes have one more advantage – they help ensure light for any type of need or premises. Cold – for offices, neutral – for hospitals, warm – for residential apartments.
Myth No. 2. The power of LED-bulbs is low and therefore not bright
It is luminous flux, not power, that must be evaluated while selecting a light emitting diode lamp. It is measured in lumens (Lm) and is also indicated on the package. The higher the intensity of luminous flux is, the brighter the lamp. For instance, a 60W incandescent light bulb and a 9 W LED-bulb will be equally bright, because they create a 800 Lm luminous flux. This means that while consuming less power, light emitting diodes ensure a high level of lighting, thus providing for the saving of electricity.
Myth No. 3. LED-bulbs do not come with standard sockets
Light emitting diode lamps are manufactured with all types of standard sockets and, respectively, the use thereof with standard sockets does not cause any difficulty. These include Edison screw sockets labelled with the symbol "E" of various diameter – for instance, E27 (standard) and E14 (narrow). Or bi-pin connectors, labelled with "G" or "GU" symbols. The number after the symbol represents the distance between pins in millimetres – for instance GU10 or G5. Thus, you are able to replace an incandescent light bulb with LED-light sources with identical sockets at your home yourself.
Myth No. 4. LED-bulbs are expensive
It would be more correct to say: more expensive than incandescent light bulbs. However, if the basic positive factors are considered: high energy efficiency and long service life, their comparatively high price pays off very quickly. Correct LED-bulbs consume little power with a high level of lighting and will serve your home for decades. The bulbs with the label A++ have the highest energy efficiency, followed by – A+. Remember that all these advantages apply only to lamps of verified, conscientious manufacturers, who guarantee quality at a sensible price.
