LED bulbs at first glance may seem expensive. It is not necessary to buy top models of Philips for 2000 rubles a piece. Chinese LED bulbs of similar luminosity are cheaper( 200 rubles).It would seem a lot, but look at the bills. If a chandelier for three light bulbs takes energy, like three stationary personal computers, you need to do something. You will see that the technical characteristics of LED lamps and fixtures will save almost half the energy every month, the main consumer, the enemy of the household budget will be. .. a refrigerator.
LED bulbs: the advantages and qualities of
Today the market is in chaos. Energy saving is called halogen light bulbs. LEDs consume even less energy with equal luminosity. Like halogen, LED light bulbs detect their own wavelength temperature: higher — colder shade. The latter is designed to satisfy numerous tastes. On the example of photos we illustrate the advantages of LED lamps. Consider the characteristics of LED in more detail.
Bulb Shape
In the first place at the Online LED lights comes the bulb shape A60.Describes the appearance of the light bulb. The parameter is described by GOST R 52706( Incandescent Bulbs, Appendix D).The letter A is marked with a LED bulb with a rounded end thickening. In fact, the types M and PS are the usual roundness of incandescent lamps. The number 60 denotes the diameter. The shape of the bulb repeats the incandescent lamp, it can be completely different.
A60 flask
Glass flasks
Perishable frosted LED bulb( see photo).For incandescent bulbs in the marking there are letters ML, MT.The LED source is Chinese, because the characteristics on the box are simply indicated by words. Sometimes the matte color of the LED light bulb means: a phosphor has been applied to the surface. This will allow smoothing the pulsations, will give uniformity to the glow, the main thing - hides the filling from curious glances( gives the product aesthetics).
Dimensions of the
LED bulb The characteristic is not always indicated, but the first item in the list is confirmed: the diameter is indeed 60 mm( length 106 mm).
Base
Considered to be the most important part of a light bulb, it won't turn into another cartridge. Used E27 threaded Edison. Standard de facto territory of the USSR for chandeliers. It is important to check the parameter in the store, sellers unknowingly often try to push in for inspection E14, other sizes. There is a variety on the modern market. The dimensions of the LED lamps are different, we will find models on almost any base, including a voltage of 12 volts.
Power
The 10 W parameter indicates how much a light bulb will consume from the network. Indeed, in practice, measurements give smaller values, even 10 watts will impress: now the hall chandelier will consume a maximum of 50 watts( less than a typical stationary personal computer).
The real luminosity of the
Began to evaluate in the usual watts of incandescent lamps. In reality, according to subjective assessments, the class of devices under consideration is brighter. On the box is written 75 W, shines like 90 bulbs. When consumed chandeliers 50 watts will give as much light as 450 watts Ilyich spirals. Agree, rather big difference.
Clear luminosity of the
lamp
frequency A parameter of 50/60 Hz indicates that the device is suitable for use in European countries( the United States was not included in the list due to the different amplitude of the supply voltage).
Operating voltage
Varies in the range of 176 - 264 volts. Consistent with most international standards. RF applies GOST, prescribes to give 230 ± 10% volts. The bulb covers the range, provided with a significant margin. The type of LED lamp base is indirectly dependent on the supply voltage. At 12 volts are mostly male connectors.
Color Temperature
Parameter 4000 K shows: fluorescent lights. They are really powerless to block the sunny side( south), they shine brightly in the twilight. A colder tone( higher luminescence temperature), shade is suitable for the purpose of creating a working environment. On the contrary, for a bedroom, buy products that provide 2,700 K, will help you easily fall asleep. By the way, breaking the rule is not as harmless as it would seem to the layman: the wrong distribution of lamp luminosity by the hour of the day leads to disorders of the circadian rhythms. Stores lay out appliances that have a regulated temperature. Will be able to provide the right conditions around the clock.
Luminous flux
The parameter reflects the luminosity of the lamps. It is 820 lm. The figure says little to most buyers. Above is the characteristic of recalculation of numbers on the bulb.820 Lm approximately correspond to 75 W.
Luminous flux of light bulbs
Color rendering index
The parameter above 70 says: 70% of colors correspond to reality. The white table will remain such, the green wallpaper will not lose the qualities of a young meadow. The ideal is a reference source of equivalent temperature. In the laboratory, determine the color rendering index of a specific lamp.
Angle of dispersion
The ideal angle is 180 degrees. Achieved thanks to the plastic part. Flasks, deprived of an opaque casing, shine in all directions. The restricted light bulb provides a pronounced radiation pattern with a downward slope. Not all products supply an opaque part.
The operating temperature of
From -40 to +40 degrees indirectly indicates the range of applicability of the device. In practice, readers will be surprised: the energy saving of LED lamps is complemented by the absence of heating during the work period. So, at any time you can unscrew, replacing. Conveniently, considering that it is easy to burn a hand about the bulb.
Weight
52 grams will allow you to check the kitchen scales. Our last behaved just fine( the value coincided).Specifically for the consumer, the mass of the bulb does not carry any physical meaning.
Dimmable
LED light not dimmable - the brightness can not be changed using special devices. Products low prices. Dimmers cost resemble trivial switches. They are characterized by the presence of a knob, turning the power supply voltage of the LEDs changes. Incandescent light bulbs could all be equipped with dimmers, the class of instruments in question is not always suitable.
LED Light Specifications
Lifetime Duration impresses, let's look at the figure together - 30,000 hours. It means that the functioning is ensured for 1250 days without a break, it is over 3 years. If you turn on the lighting no more than 8 hours, the term will reach 10 years. There are light bulbs, where the manufacturer promises a longer period.
Warranty period
Sore spot for Chinese products. For example, on Camelion bulbs it is written: the warranty is valid for 3 years, when after examination the seller replaces the burnt product. In reality, they encountered difficulties: by the phones indicated by the official Camelion website, they answer reluctantly. E-mail is completely crowded, messages turn into the error "Yandex is unable to deliver the message."Therefore, we consider the choice in favor of Onlayt justified: saving twice, luminosity is lower( the eye almost does not notice), there is no guarantee( through the dealer).
Flickering LEDs
Shooting in public places is not prohibited with rare exceptions. Therefore, take the bad - the worst you can get - the camera, go to choose.
Note, light bulbs, more expensive Onlite( 180 rubles) flickered with accurate focus. It will be noticeable only in photo mode, when the camera is really poor quality. It is better to take an old mobile phone, low quality iPad. It is important to focus correctly( on the tablet is done by clicking the finger on the touchscreen).Poor quality LED light - a noticeable flicker.
Disadvantages of
LED bulbs The main disadvantages of LED lamps are named. This is:
- Lack of warranty for cheap Chinese models( including “European quality” imitator firms).
- Flicker of individual products.
The second moment is important, imperceptible to the eye beats will cause mental disorders( see the license agreements of computer games).Choose by grabbing the camera. Return of LED lamps will please. Deductions to energy nonsense - reduced wiring requirements. The allocation of power is directly determined by the current drops by an order of magnitude. Useless energy loss in the thickness of the wall is reduced tenfold. An additional plus, not obvious, is little discussed by the press. At the same time, the requirements for switches and luminaires are falling: 10 A current cannot be accumulated when using LED lamps.
It is important to remember the following:
- The apartment will now consume 200 watts maximum. The current barely reaches 1 A.
- The total power of the LED lamps is small, the savings on the accounts of management companies will become noticeable in the first month of use.
- The requirements for various sensors are eliminated. You can cover the apartment as it gets dark by choosing the automatic mode. You will need a light sensor. Technical characteristics of LED lamps will allow you to use one copy per apartment.
It is important, because the specific cost of a meter of cable is determined by the cross section, the light sensor costs money. Using LED bulbs, we save by rare replacement, gradually reduce bills, the cost of additional equipment. Chandeliers are acceptable plastic, characterized by the minimum allowable capacity. Of course, a fire is possible, caused by poor-quality contacts, the chance of fire reaches a minimum.
We get cheap light, thin wires into the wall, minimal risk of fire insulation, cheap sensors, switches. Safety machines former price. One piece is enough to equip the premises, providing a huge stock. We are sure that neighbors do not flood their readers every day; you can replace chandeliers without turning off the power, if the wiring is done correctly. In the end, we see the future of LED lights, saving a lot of energy.
