Energy-saving lamps: is fluorescent lighting economical? – free-credit-report-check.com

Energy-saving lamps are a type of fluorescent lamps; this is their compact version. Now there are many models of energy-saving lamps on the market. They differ from each other in such qualitative indicators as the range of the emitted spectrum, base, type of cartridge, shape (for example, arcuate or spiral), size and technologies used in production.

Domashnie-dela.RF – Shall we change the “light bulb of Ilyich” for an energy-saving lamp?

The difference between an incandescent lamp and a fluorescent lamp

The incandescent lamp works on the principle converting electrical energy into light energy. In an incandescent lamp, light begins to be emitted after the tungsten filament is heated to 3 thousand * C when a current passes through it in a vacuum or an inert gas. Vacuum or gas is needed to protect the filament from oxidation. A lamp with this principle of operation when illuminated is always very hot.

The principle of operation of an energy-saving lamp. The bulb of such a lamp is coated from the inside with a special substance – a phosphor, due to which the invisible ultraviolet radiation from an electric discharge becomes visible. And the discharge appears from the passage of electric current through the mercury-argon medium, which is located in the flask. The discharge power is regulated by a starter built into the lamp.

Advantages of energy saving fluorescent lamps

They give more light output with less energy consumption. This is especially true in winter, when most of the day is dark, and the lamp turns off less often. In an incandescent lamp, almost all of the energy is spent on heating the filament.

Longer energy saving lamp life, which is up to 15 thousand hours of operation. This is 20 times more than that of the “light bulb of Ilyich”.

You can choose the type of glow: warm, cold, neutral.

Slight heating of the lamp. Therefore, the plastic part of the lamp holder and electrical wiring do not deteriorate from melting.

There is no lamp flicker. The uniform glow of the lamp occurs due to the built-in capacitor, which maintains a constant frequency and intensity of discharges in the lamp (up to 50 thousand / sec at 50 kHz).

Disadvantages of new generation energy-saving lamps

Energy-saving lamps are more sensitive to power surges, so they can quickly burn out.

Part of the spectrum is missing from the lamp radiation. This can distort color perception and lead to eye fatigue, especially when reading. That is why it is better not to use energy-saving lamps in table lamps.

It takes a few minutes (2-3) to fully warm up the lamp

It is possible that the lamp flickers when its resource is depleted from frequent switching on.

Temperature sensitivity. At -15-20 * C, the lamp does not work. At high air temperatures, the intensity of illumination is lost.

Ambiguous behavior of the lamp at high humidity, for example in the bathroom.

The high price of energy-saving lamps.
Yes, indeed, the cost of such lamps pays off only when used in the long-term on state. And this rarely happens in the home.

Harm from using energy-saving lamps

Ultraviolet radiation. Therefore, the distance from the lamp to a person should be more than 50 cm. In residential areas, it is generally better not to use energy-saving lamps with a power of more than 20 watts.

Fluorescent lamps contain mercury and phosphorus. Therefore, after use or damage, the lamp must be disposed of.

But here, in fairness, it should be noted that recently manufacturers of energy-saving lamps have begun to pay great attention to protecting consumers and the environment from the negative effects of fluorescent lighting fixtures. For example, mercury is already added to their composition in a bound form (calcium amalgam), and a phosphor in powder, which significantly reduces the risk of poisoning.

In addition, they have become more popular in recent years. LED lamp. They can become a serious alternative to fluorescent lamps. LED lamps are also energy-saving lamps, while they have much fewer disadvantages and harmful effects on humans and the environment.

How to choose and what to buy energy-saving lamps

When choosing energy-saving lamps, you should pay attention to the technologies used in production. The lamp must have a warranty period. It is better to buy dumps with the sign “ECO technology”. The use of SMD and PCB assembly and machine soldering increases lamp life. Filters should not be missing to suppress spatial electromagnetic interference, which increase the life of an energy-saving lamp.

As for the choice of a lamp manufacturer or a specific model, the answer here is standard. It is better to buy lamps from well-known manufacturers: Philips, Osram, Feron, etc. There are also manufacturers who have proven themselves not in the best way. Feedback from buyers of their products can be found on various forums dedicated to the discussion of household appliances and electrical appliances.

The idea of ​​switching from incandescent lamps to energy-saving lamps in Russia, as is most often the case, is an initiative from above. Looking at the situation with the widespread use of modern lighting lamps in countries with developed economies, the leadership of our country made an interesting conclusion. It turns out that the development of Russia, and even more so its prosperity, is not possible without the universal introduction of energy-saving lamps. I immediately recall one of the “Testaments of Ilyich”, pronounced by him already in 1920: “Communism is Soviet power plus the electrification of the whole country”, in accordance with which “Ilyich’s lamps” were victoriously lit throughout the territory of Soviet Russia.

Could there be another hidden meaning here? Having finally abandoned incandescent lamps – those very “Ilyich bulbs”, does the Russian leadership want to finally put an end to the Soviet past, to put an end to all the ideas of the Bolshevik-Communists? Anyway. From introductory words, it’s time to move on to the essence of the problem. And then some politically oriented post about household electrical appliances turns out. Probably, the pre-election moods of others have an influence. So, it is obvious that you still have to switch to new electrical lighting fixtures. So let’s try to find out what are the main pros and cons of energy-saving lamps.
