For many years now, there has been an active promotion of energy saving in all media, and various so-called energy-saving lamps are constantly mentioned. But we know that any landlord will say that he is primarily interested in two issues - the cost of a light bulb and the duration of its service. Let's try to figure out whether such an energy-saving lamp is really better than the usual light bulb with a filament and if so, how to choose it correctly.
Types of energy-saving light bulbs
Energy-saving lamps are of two types - fluorescent and LED.Perhaps the main difference between the "new" lamps and the "Ilyich bulbs" is that they use all the energy they consume into visible light, without any losses. But incandescent lamps "give" us in the form of light no more than 10 - 15% of the consumed energy. Ask where the remaining 90-85% of energy goes - it is converted to thermal radiation. So, our usual light bulbs rather warm than shine. Therefore, when buying an energy-saving lamp, you need to think about where it will be installed.
Choice and purchase of the lamp
When buying a lamp, it must be checked in the store, and in the presence of the buyer. You should wait until it flares up completely, and not just make sure that the lamp is lit - this will take 2-4 seconds. After the lamp goes out to "mode", you need to pay attention to the way it lights up. There are lamps of cold and warm white light. The first is advisable to install in subsidiary, non-residential rooms, so they are often used to illuminate premises in various organizations.
And here is a warm light, of course, it is better to buy for a house, an apartment. There are also lamps with a color temperature of half the size, and they are great for rooms such as a kitchen and bedroom. The color temperature and the color of your new lamp will be indicated directly on the package.
If the lamp is taken for a specific illuminator, then you need to take into account that energy-saving lamps have slightly larger dimensions. It will fit, say, in the plafond, or not - a question. However, there is a big plus, among others - such lamps in the process of "work" do not heat up, unlike incandescent lamps, so they can be safely put in lighting equipment from any material.
Naturally, one must bear in mind that energy-saving lamps are produced in many countries. Experts advise buying products made in Europe and, do not be surprised, in Russia. It is the lamps of these manufacturers that have proved themselves well. It seems that we should not talk about lamps manufactured in China. Do not need to rack your brains, which of the two lamps you choose - spiral or arc. Despite the different shape of the gas cylinder, their characteristics are exactly the same, so the main thing is to fit the size. By the way, such lamps are still similar to a pear or a ball - it depends on the manufacturer's imagination.
It is necessary to pay attention to what the manufacturer and the seller give. Serious manufacturing companies guarantee a warranty period of 2 years. However, some sellers "cunning" and give their own, "sales" guarantee, which is much "more modest".If so, then it is better to buy a lamp in another trading organization. It seems that there is no point in talking about the identity of the lamp cap, which is taken for a certain lighting device, and a cartridge.
These are the very starters that we are used to in daylight lamps and who often mislead us about their usability. Well, this is perhaps all that the consumer needs to know about energy-saving lamps.
