The opportunity to save energy consumption and optimize its payment costs looks attractive. Recently, housekeepers have become popular - lamps that really allow you to reduce costs, while not inferior in quality characteristics to conventional incandescent bulbs. With their help, you can organize comfortable lighting, apply warm or cold light, and their service life is at least 30 thousand hours.

Specifications
Incandescent light bulbs have become obsolete in both living quarters and offices or manufacturing facilities. The invention, which initially frightened buyers with its relatively high cost, quickly proved to be worthwhile. The economic feasibility is quite obvious: instead of a 60 W lamp, you can install a light source power of 10 W and at the same time get no less bright luminous flux, evenly distributed over the entire area premises.
One of the characteristics that people pay attention to when choosing an energy-saving light bulb is its color temperature. Depending on the type of glow there are three types of devices:
-
with a warm luminous flux at a temperature of 2700 degrees Kelvin (optimal for rooms where there is no requires eye strain and does not perform tedious work for the eyes, for example, for the kitchen or zone recreation); - with daylight - glow temperature 4200 K (energy-efficient solution for children and living rooms);
- with cold light - 6400 K (suitable for organizing lighting in offices and home offices, as well as in any rooms where work requires maximum eye strain).
With the correct color temperature, visual fatigue is absent during the entire stay in the room. If the eyes get tired quickly, the ESL lamp should be replaced.
Another one an important technical characteristic is light output. It characterizes the degree of propagation of the flow, is determined by the power of the device and is measured in lumens. This parameter is indicated by the manufacturer on the packaging.
The main parameters also include power. Even at minimum power, the device is capable of emitting 80% more light flux than a simple lamp. incandescent (for example, an ordinary 150 W bulb emits 1900 lumens, the same flux is given by the housekeeper only in 30 W). It is not difficult to calculate what the savings will be during the first month of ESL operation.
Types of devices
In the assortment presented by the manufacturers, you can choose an energy-saving light bulb for an apartment in accordance with personal needs and characteristics of the room. Such lighting fixtures are a worthy alternative to Ilyich's lamps. For household and office lighting three types of devices are used:
- luminescent;
- LED;
- halogen.
All of them have a high efficiency and at the same time minimize the load on the electrical network. This increases the level of safety in the operation of lighting devices and equipment available in the house. The newest LED ESLs are considered the most environmentally friendly, economical and safe for humans.
All products are manufactured with markings corresponding to the type of base. For luminaires equipped with standard-sized sockets, E27 bases are intended, for small diameter luminaires - E14 bases. For floodlights, lamps with the E40 marking are used. Classification of energy-saving lamps by shape represented by the following models:
-
U-shaped; - spiral;
- semi-spiral.
The most expensive are spiral bulbs, but not because they have the best technical characteristics, but due to the complexity in the manufacture of the structure. The quality depends directly on the manufacturing company. For example, Chinese counterparts of expensive products are inexpensive, but they are unreliable in operation. Well-known companies give a 3-year warranty, while cheap products will last no more than 1 year.
Main advantages
Energy saving lamps have been proven to be efficient and economical. In addition, they have other advantages that consumers have already appreciated. The advantages of using such devices include:
- long service life, almost 10 times higher than that of incandescent lamps;
-
less intense heat production, which minimizes melting of plastic parts of cartridges and wires; - minimizing the load on the wiring;
- no heating of the case;
- safer and more beneficial luminous flux for the eyes;
- even distribution of light due to the larger area of the luminous body compared to spirals in conventional bulbs;
- different color temperatures for all types of rooms.
This set of advantages allows ESL to oust standard lamps from the market almost completely. In many countries of the world, people prefer them, abandoning devices that have been popular for many decades.
Utilization of housekeeping systems should be carried out taking into account safety requirements. Products contain mercury, which has negative health effects. Therefore, it is not recommended to use such lamps in devices located at a distance of less than 30 cm from a person. A cracked or broken product must be urgently taken out of the house and disposed of.
