Energy-saving lamps: types and price, market review proposals

Economical power consumption helps to save significant funds. It is therefore not surprising that many users stopped using the classic incandescent lamp to equip residential and working areas. This article describes the energy-saving lamps, Type and price. Compare them with alternative sources of light will help to make the right conclusions.

How to choose energy-saving lamps: type and price, and other important parameters

These fuel-efficient light sources - the well-known gas-discharge lamps with a modern edge.

Such light sources are rarely used in residential premises. They have impressive dimensions, are connected to a special patrons. For them it is necessary to start to use a separate electrical circuit. Major fragile flask can damage not strong blow. It must be remembered that within it are harmful chemical compounds. When the integrity of the violation - it is necessary to ventilate the room.

But these shortcomings are deprived of modern models.

They are created in the form of spirals with other complex shapes. When the length necessary for stability of maintaining the discharge in the gaseous medium has turned out to provide the compactness. Some models (as seen in photo) are fitted with a special bulb. It protects against mechanical stress, which prevents accidents mentioned above.

Instead of a separate "starter" built-in used Tsokols trigger. Externally, it is not noticeable. Particularly pleased that these electronic components, unlike their predecessors, do not emit any noise during operation. They will start the lamp and are able to perform their functions in full for many years.

To maintain objectivity, it should be noted some decrease in luminous flux. It occurs when the air temperature drops below 0 ° C. Therefore, this shortcoming can not be taken into account for indoor environments. In some products the ignition time is several minutes. This is typical for high-end versions of the lamps, which are rarely used indoors.

Technical parameters of luminescent devices

Make it easier to compare different light sources, the following are features of the main characteristics:

• Manufacturers specify capacity in watts. This option only reports on energy consumption.
• The luminous flux in lumens lead (abbreviated as "LM"). Saving lamp with a power of 10-12 Watt consumption can create the radiation in the visible wave range from 800 to 900 lumens.
• Color temperature describes the feature of the spectrum. From 2500K to 2800K - is pleasing to the eye with light yellow shade. If the value is from 3900K to 4200K - white light, as in the classic fluorescent "tubes".

You can also find out the time taken by the unit to switch to the operating mode after power. Some manufacturers reported a warranty operating time hours until the brightness is reduced to 70% compared with baseline.

Types of LED lamps

is the main competitor of luminescent devices LEDs. It should therefore be separately explore the features of modern products in this category.

Not so long ago it was hard to find LED bulbs socket type E14, which provide the light flux more lumens 550-650. For comparison it should be noted that this radiation produces an incandescent lamp with a capacity of about 60 watts. Thus, there have been problems with the equipment of large rooms.

It is also necessary to mention the incorrect data, which resulted in many Chinese manufacturers for their products. They overestimated the power of distorted information about real color temperature, do not perform warranty obligations. But gradually the situation is normalized. On the market there are high-quality products at a reasonable cost.

In these lamps light sources - semiconductor devices. They do not need the gas medium and high voltage discharges to perform their functions. To use low voltage power supply. The corresponding drive is mounted in the base part. Visible only outside the cooling fins (in some models). These fixtures resistant to mechanical stress. They are designed for long life, up to 18 thousand. hours and more.

To properly compare LED and energy-saving lamps, Types and prices, you can use the same technical parameters that were discussed above:

• power consumption;
• light flow;
• color temperature.

TABLE power saving lamps and other light sources

Ranges of numbers in the tables include data on products from different manufacturers. In certain positions of error in the technical specifications of energy saving lamps and other devices are associated with differences in measurement methodologies.

Comparison of energy-saving and LED lamps with legacy devices

Even taking into account the possible inaccuracies in the above data is not difficult to draw the following conclusions:

• New types of instruments (LED and energy-saving) consumes little energy. Outdated incandescent lamps create "parasitic" radiation in the infrared spectral range. It raises the temperature inside the premises, so in the summer period there are additional costs cooling. In winter, however, it is not enough to replace heating systems.
• Fluorescent lamps need more power to produce the same luminous flux as compared with LED devices. The difference is about 1.8-2.5 times. However, as long as these products are cheaper.
• The smallest life of incandescent lamps. Despite its overall "work experience" is not able to significantly improve their technical parameters. Such a product fails after 4-5 months in normal operation. Some manufacturers of energy-saving compact fluorescent lamps modern models provide the preservation of functionality after 9-10 years of use.
• In terms of resistance to mechanical stress in the lead - the LEDs. Not always this option is essential. However, one must understand that an accidental fall can destroy thin glass fluorescent tube. The tungsten filament is damaged even minor vibrations.
• By reducing the level of stress in a special part of the power supply circuit LED device automatically performs the necessary adjustments. The user will not even notice these shortcomings. In the same situation, the filament will emit less light, and energy-saving lamp can be turned off. However, the voltage regulation is intended only to certain minimum values. Usually it does not exceed 20% of the nominal value.
• Incandescent lamps win on environmental characteristics. Luminescent devices disposed recommended using special techniques. As part of LED lamps also have a lot of chemicals that pollute the environment. However, the comparison must be correct. It should be noted that the old appliances consume about 10 times as much electricity.

Production technology is constantly improving. change frequently rates energy companies. That is why an accurate comparison of financial performance is not possible. You can take the actual data, analogs incandescent lamp of 75 watts. Savings of 8-10 years will be using the following devices:

• LED - from 4500 to 6200 rub .;
• Energy saving - from 3900 to 5800 rubles.

The calculations were performed taking into account the expected life and replacement of damaged items published.

It is harmful to human health saving lamps

Concerns about the hazards should be based on facts. Fluorescent lamps are used for decades. Accumulated data not only laboratory tests, but also practical tests. Not difficult to find on the Internet reviews of ordinary users and reputable expert advice. After studying the subject information can note the following important details:

• The emission spectrum is not harmful to human health.
• Discomfort can create products of poor quality, by dubious manufacturers. Defects are manifested in the form of extraneous sounds, random changes in brightness.
• To prevent ingress of chemical compounds in the atmosphere of the room, it is necessary to exercise caution when handling the devices. Current models provide strong enough so they will not break if dropped from low altitude.

Note! Sometimes saving lamps flash off. This does not necessarily - a sign of malfunction. Check whether the switch is not set with built-in lighting in the supply chain. A current through it can be supplied to a lamp trigger circuit.

Products of famous brands are more expensive. But they differ in the best quality. Their manufacturers specify all the characteristics that you need to know to potential users. In addition to these data in the table you can find out the service life in hours, the exact dimensions and other data. However, new brands are actively gaining its market share. They are introducing new products with high consumer properties offer lower prices.

General conclusions

In the study of energy-saving lamps, types and prices, other common characteristics, it is necessary to take into account their purpose and operation conditions.

The comprehensive assessment of the technical parameters of the lamps must be added the expected life and the manufacturer's warranty.
