The lighting elements on 220V this type are characterized by such parameters
The color temperature of the lamps
In addition manufacturers often specify the brand of LEDs which is a key factor in determining the length of the bulb and will affect the value of the product. It is also customary to indicate the power level of the analogue with the same intensity of radiation.
First of all, we note significantly longer period of operation of the lighting elements LED. The period varies depending on the model lamp type diodes provided for in design and can range from 30 000 hours or more. Different manufacturers guarantee different periods.
The diode light sources at 220V economical as it consumes much less energy which distinguishes them from the halogen analogues which by the way operate just 2,000 hours.
The brightness level of the led light bulbs and analogues with a filament filling of the bulb the Halogens may be the same but the power of be different many times. For example, consider a LED product with base G9 5W. The luminous flux of this model is 400 LM. Halogen counterpart will provide the same result at a power of 40W.
Heated diode light sources during operation is also substantially less even with a rather large for such light bulbs 7W 9W load and more. Due to the strong heating of the halogen analogs are not suitable for use in certain fixtures. Both are installed the same way just the cap is inserted into the connector.
On the reliability of the diode light source is far superior to all other counterparts as it is often made of plastic of metal.
The choice should be made on the basis of which the lamp is to be mounted diode light bulb 220V plug socket with an open or closed canopy. On the basis of this selected model with the radiator or without it as in enclosed fixtures, the heat dissipation is difficult. In addition, at this stage, taken into account and a sufficient level of brightness for a particular object. The more powerful the light source the stronger it will heat up and hence the lamp with a heavy load always equipped with radiator 5W or more.
The brightness level of a product is determined by a number of parameters luminous flux colour temperature and colour rendering index. The type of lamp on the preferred design of the light source.
For example, a bulb with a scattering angle of radiation of 240 degrees, provides illumination of a smaller plot of land. But if the design of the lighting device allows you to use these bulbs without loss of quality lighting provides a large number of light sources ceiling outdoor and is characterized by a specific configuration. It is also important that the lamp was provided with special connectors for the installation of lamps with pin base.
The market offers a very large selection of versions with G9 holder of different brands. Some of the most famous Osram Philips Samsung Navigator Feron Gauss Uniel. The products of these manufacturers are popular due to high quality products. However, the cost of bulbs is high 200-400 rubles per model capacity 25-5W. Accordingly, the higher the load the more expensive light source.
The most expensive models provide high luminous intensity at the level of the halogen lamps 100 watts.
Users very popular products Samsung Gauss Uniel in addition to industry leaders Osram and Philips. It is important that the bulb was equipped with a radiator and was of good quality soldering. This will provide a much longer service life.
In practice, problems usually occur ring sources of light. Such products often do not meet the specs shines weakly and briefly consumes far less power than specified. In addition, the autopsy can detect the low quality of the soldering of the structural elements.
So you need to consider products from reliable brands offering long-term warranty of 1-3 years as all manufacturers of the above list. The quality of the radiation they had enough and the lighting is always consistent with the stated parameters. Lifetime is also specified real. A long period of operation due to high-quality crystals which are used in construction.
In addition, many reliable manufacturers enables the emitters of its own production Samsung Uniel and some others. The result is more expensive initially, the products will cost less than regular replacement of low-quality Chinese light bulbs because of their burnout.
Thanks to economical consumption of energy and high intensity of the emission diode lamps in the end will pay off quickly as they have been used for several years.
