7 Myths about LED Lights

One old lady told that the promotion of LED lights and a ban ordinary light bulbs is part of the conspiracy lighting manufacturers and governments worldwide. She also said that under the glow of LED bulbs wrong flowers grow. Actually, these LEDs not properly lit, in a few weeks begin to flicker and all the LED light stuff only used thugs to burn the marijuana plantations. Do you know the most common myths about LED light bulbs?

Almost every change from business as usual in humans causes strong reactions and often meets with incomprehension and a wave of criticism from various “experts”. In the 70s of last century, when information technology was in its infancy, watching various critics on personal computers as something that happens most passionate hobby for a few handymen. In the eighties, they turn bad language claimed that the mobile phone need only financial magnates-type uttered by Gordon Gekko. In 2002, two years before starting Facebook again predicted the fall of the Internet.

What are the myths and half-truths circulating about the latest technological novelty in the field of lighting?

Myth 1: The LED lights in perpetuity and never otherwise

Neither LEDs will not last forever. According to mbakechengLED lamps may illuminate and 50,000 hours or more, while their luminous flux drops to 70% of original value. It is still considered acceptable decrease the brightness of light for normal lighting. They should lit 24 hours a day, lasted six years, which is many times more than ordinary light bulbs and more than twice as energy-saving lamps long life.

Myth 2: The global conspiracy hatched bribe MPs and manufacturers of lights

Laws liquidating sale of ordinary bulbs allegedly bribing MPs have signed large companies that manufacture lighting.

If that were so, they would have a big wad of money, because “Legislation on demand” against famous invention, which boasted the likes Edison, had become a big wad of cash. A similar statutory framework for the gradual suppression of incandescent lamps is accepted in the United States, China, Australia, European Union countries, Switzerland, Israel, Brazil, Canada, Russia, Cuba … and so on. For obvious reasons, they remain behind mainly African countries.

Myth 3: LED bulb glows pale blue and shortly blink

The first LED bulbs have different flaws. Today, we can also be dimmed (at least some types), or choose different shades. Unless the Chinese Suntech imports or flashing should not be a problem. If the flashing does, you need to add a circuit at least one ordinary or saving bulb that creates a lack of resistance, and the flashing stops.

If you are not enough of these arguments, see, what lights are used for their equipment manufacturers of cars, televisions, lighting and industrial equipment. If the LED lights had not been paid and bad qualities, large companies would they “neprznily” their products.

Myth 4: Recessed LED lighting plants in flower or Pšenka

Withered you another poor plantation, but can not admit it because you cared little about it? Before you start blaming the wrong LED light source, recalling the known facts. Plants thrive when you can choose the intensity and color spectrum of light. It likes to purple, bluish and red. The violet to blue color corresponds to wavelengths from 400 to 520 nanometers (nm), while the red color has a wavelength in the range 620-700 nm.

Conventional lit LED chips having wavelengths ranging from 400 to 760 nm. So it’s the correct choice of LED sources, which will come in handy for your flower. Once you poor thing die more green, the Swede needed to neighbor, who honestly without watering when you were just on vacation.

Myth 5: LED bulbs emit no light

It is true that LED bulbs do not leave any radiant heat. However, LED lights also must escape conductive thermal energy. That is the reason why some LED lights have a built-in heat sink that delivers greater energy efficiency.

Myth 6: LED light sources are too expensive

When you go to an electronics store, prices speaks clearly in favor of compact fluorescent lamps or ordinary bulbs intended for industrial use. Acquisition costs are but one component of the total cost of home lighting. When you add into the equation as well as operating costs (electricity consumption bulbs and any repeat purchases), we arrive at a completely different result. When comparing the overall costs of the various light sources within 10 years appeared best right LED lamps.

Total costs for lighting 1000 hours each year come with LED lights to CZK 730 for CZK 785 CFLs and halogen lamps 2265 CZK. The data were processed in the framework of the research project Premium Light.

Myth 7: saltpetre with power 3 watts shining brightly than 1 watt

In incandescent light bulbs, we could clearly say that the 100wattové bulb “Drawing” brighter light than the less powerful 60wattovky. Saltpeter in the world, but nothing is as it seems. Simple mathematics at the LED light sources can not be applied, as they are often light-emitting devices of different materials and therefore different properties. The standard light bulb shines in all directions as well, this LED lights do not pay.

For example, where it at table by lamplight before enough 60wattová bulb can also insert nitrate with less power in watts, but you get just enough light for reading books. With less power consumption in watts LED bulb is created equal or higher luminous flux in lumens, which determines how well you shine.
