Technical development never stands still, and replaced by years of proven home appliances and devices come all new, more advanced models. Often at first this causes distrust, but very soon the new items take pride of place in the everyday life of users. Only if, of course, if they are really useful. Such important inventions of mankind include the growing popularity of LED lamps. Reviews on most sites speak in their favor, but still it is worthwhile to dwell on some important features. So where and why can LED lamps be used?
Application area
LED technology has replaced the so-called "energy-saving" lamps. The latter, in fact, are the same ordinary fluorescent incandescent lamp, only with a built-in adjustment device. The latter allows you to significantly increase the life of the model and thereby reduce the cost of regular purchase of new ones. But this useful find is gradually becoming a thing of the past, because LEDs have replaced it. The technology for their creation was invented in the last century, but found the necessary resources for implementation only in our days. New lamps can be used both in flashlights and car tapes, and at home as a replacement for standard bulbs. They are also great for installing colored lighting (for example, in a nightclub) and indicators in the workplace.
Customer opinion
In the question of whether or not to use LED lamps, reviews from other consumers who have already tried this type of lighting will be most welcome. Perhaps they will help the buyer make the right decision. Below are the pros and cons of LED home lighting. Like any new product on the market for technical devices, this invention is controversial. There are industries where LEDs are simply irreplaceable, but they are far from always practical.
LED bulbs: positive reviews
One of the valuable advantages of such lighting is its absolute harmlessness. Unlike other lamps made on the basis of energy saving technology, LED lamps do not contain mercury and other harmful substances. Another plus is that their spectrum does not emit ultraviolet, which is hazardous to the eyes. Often, it is harmful radiation that causes fatigue, and in the future, a decrease in visual acuity in people. Such lamps do not heat up. Of course, the main incentive for the acquisition will be unsurpassed profitability, because the power consumption of LED lamps is much lower than that of analogues. This type of lighting consumes three times less electricity than energy-saving lamps and almost nine times less than conventional fluorescent lamps.
This significant difference is reinforced by the long life of the LEDs. Manufacturers promise more than 30,000 hours of continuous operation, which exceeds the life of conventional lamps by several (!) Thousand times. Upon purchase, a guarantee is given for a period of three to five years. The base of these lamps meets the usual standards, so that the use in everyday life does not require any special conditions. The light temperature of LEDs is divided into three main types: yellow, lighter and cooler white. For the house, it is enough to use the first type of lamps with a pleasant warm shade of rays. They have a designation from 2700 to 3500 ° K. Higher power is suitable for working industrial premises or, for example, bright storefronts.
LED bulbs: reviews against use
The main disadvantage of using such bulbs is the relatively high cost. Despite the obvious benefits of their use, many people still prefer the old, proven options. Another nuisance that limits the introduction of LEDs into everyday life is narrowly focused light. LEDs do have a less diffused flux than other types of lamps, so when equipping a house, more devices may be needed. This is especially noticeable on the example of street lighting, which with rare placement of lamps can turn out with stripes of dark areas. It was also noted that by the end of their life, LED lamps gradually lose brightness (about 10-20 percent).
As can be seen from the above, consumer opinions are divided almost equally. Despite the grandiose future predicted by him, LED lamps have not yet displaced their analogues from the market, but they occupy a worthy place on store shelves. And the choice is always what the lighting is best for the buyer.
