Energy-saving lamps: types and their differences, the price of a variety of CFLs

Fluorescent energy-saving lamp: the pros and cons

Energosberegaek positives have clearly more than the negative. Let's try to list them:

And what about the negative sides? As with any tool, there are:

However, with such defects can be tolerated, because, unlike incandescent bulbs, energy-saving almost 80% on lighting costs. And although the most economical light bulbs for homes are LED, the savings when using ECL (compared to "light bulb Ilyich") is very significant.

What it is in energy-saving lamp: operation

The structure of energy-saving lamp includes bulb, housing, base and electronic ballasts (in other words, the ballast). The bulb is filled with mercury vapor and is covered on the inside with phosphor. This is a special substance that converts ultraviolet to visible to our eyes glow.

Electrodes, positioned at opposite ends of the bulb, the electrically begin to heat up, creating a flow of electrons. They, in turn, collide with molecules of an inert gas and mercury vapor, which emits ultraviolet light. The human eye is not visible. That is why the internal walls of the flask suffered a phosphor that converts ultraviolet light into visible light to the human eye.

Energy-saving Lamp: technical characteristics and application depending on the type of cap

Distinguish between many types of ECL base. But the main, the most common are type 3 - E14, E27, E40. This threaded caps, in which the numeral is designated diameter. Try to understand their scope.

Saving lamps E14: application and especially

Such caps are used in household lamps. This reduced the threaded cap, to which a lamp is often called "candles." In fact, their name "mignon". Most often installed in the lamp, in ovens, refrigerators, various types of lighting. Today on the shelves of electrical shops can be found as an adapter with a normal minion E27, and vice versa, which is quite convenient. You can not always find the ECL with E14.

Energy-saving lamps with E27 cap: The most common variant

Such ECL are used everywhere. Almost all lights in the apartment or private house equipped with this type of ammunition. When replacing the dwelling "bulbs Ilicha" housekeeper on (power-saving lamps) used is E27. In this case, simply unscrewed and screwed one another, without any adapters and upgrades.

Energy-saving lamps E40: where they are used

Less common variant. Such ECL generally have a large capacity. Use them more often for street lighting. To cap need cartridge E40, which is screwed XRD (arc mercury fluorescent) or HPS (sodium arc tube).

The shape and weight of the energy-saving lamps

Distinguish about twenty kinds of shapes ECL. However, the most important of them are the seven:

1. U2 - from the housing beyond the two arc-shaped bulb.
2. U3 -, respectively, 3 flasks.
3. U4 - 4 flasks.
4. Poluspiral.
5. Spiral energy saving bulb (More tightly coiled).
6. Flask - in appearance resembles an ordinary light bulb.
7. Lotus - is less common. On the surface it looks like a lotus flower from the tubes.

As for weight, then this information can be seen in the image below.

Energy-saving lamps for the house: the main relevant parameters

The main setting is power. We should think, for what purpose will be light, because the higher the power, the greater the light output. You should also pay attention to the color temperature. This parameter determines one himself. One comfortable with the "cold" light, others need a "warm", more close to the color of incandescent light.

There is another interesting option, which few people pay attention. Today on the shelves of electrical shops were dimmable ESL. Their cost is much higher, but also use more options. Optimal such ECL in the bedroom or living room. They allow you to dim the lights, make it soft and unobtrusive, or turn on full power when needed. To do this, instead of the switch, mounted a special device - a dimmer.

Table power energy-saving lamps and incandescent lamps

Let's compare the power with ECL "bulbs Ilicha" at the same power of light.

ESL manufacturers and service life of these light sources

In Russia, the most well-known manufacturers of ECL is «OSRAM» (Germany), «General Electric» (USA), «PHILIPS» (Netherlands). The brand has long become stronger in the Russian market and proved itself with the best hand, the quality of their products raises no objections. With regard to the life, that specified by the manufacturer on the packaging is not always correct. And it is not in bad faith of the manufacturer. Often blame the user. CFLs can not tolerate frequent switching - EPRU fails. Also, do not put your hand over the flask - this reduces the life of ESL services. In any case, do not connect through the CFL Motion Sensor or sound. It is fraught with frequent on-off switch.

Basically with the correct operation period of 6000-12000 ECL service hours.

The main fault: why blinks ECL

Quite often people are faced with the fact that ESL shut down from time to time blinks. The reasons for this may be several. Most often this occurs when you install the switch with indicator. The fact that pass through the small currents, which accumulate in the capacitor ballasts. Upon reaching a certain threshold gives the charge on the capacitor electrodes. It is enough for a momentary flash, then the capacitor begins again to save current. Exit - soldered in parallel cartridge resistance 10-20 ohms and forget about this problem.

Another possible cause - improper installation switch. Sometimes he breaks no phase, as it should be, and at zero. Treatment - open the switch cover and check which wire is suitable using a screwdriver indicator. If suspicions were confirmed, proceed to the junction box, where the switching contacts so that the switch is passed through the phase.

Energy-saving lamps are harmful to human health: is it correct to say

In fact serviceable ECL no harm to the person not bring. Many people think that the ultraviolet light, breaking through the phosphor layer to the eyes, resulting in possible even blind, however, is misleading. Modern ECL perfectly safe. An exception may be an option when ESL is broken in the apartment. The air gets let small, but still mercury vapor. In this case, experts advise to open the windows, gently pick up the pieces in a tight package, place the lamp falling wash with detergent.

How to choose energy-saving light bulbs: Tips Tehno.guru edition

Choosing ESL, should pay attention to some nuances. Try to figure out what the best energy-saving lamps, and how to distinguish them. The first thing to note - packing. Labels must be properly formed clear, easy to read. The package itself - without damage. Buy such products better trusted stores. Brand is also important. To date, a leader in the ratio "price? quality "is the company« Philips ».

Too low a value of ESL is to alert you - most likely a Chinese fake, which will last a long time. Do not be shy to ask the seller accompanying documentation and the certificate of conformity, even if you purchase only one light bulb - is the right buyer. If the documentation is not available, it is better to refrain from buying.

The seller is obliged to check on the ECL performance in the presence of the buyer - it is a prerequisite.

Energy-saving lamps: type and price of various products

We've already figured out how diverse can be energy-saving lamps in appearance and power, the size of the cap. Now we look at the average cost of ESL in the Russian market. Rates are as at August 2018

Products well-known manufacturers will cost a bit more expensive by about 30-50%. This is not surprising. They have already earned a name for themselves, and now the brand is working for them.

To summarize

The fact that energy-saving lamps save the family budget, is beyond doubt. However, you should not rely solely on them. The owner himself has to observe certain rules of operation. Only in this case we can hope that ECL will serve all the declared time.
