How to choose a light bulb
In our time, the consumer is offered a huge number of light bulbs, but it is not enough to know which species they are, and which means their external (directly say, not so significant) difference. The difficulties of choice delivers the fact that different types of light bulbs are used in different situations. In order to understand the illuminating theme in general, consider each type of electric lamps separately. Mass of manufacturers, varieties of lamps in size, shapes, power ... Such a state of things even experienced buyers will make think of, not that inexperienced beginners.
What types of lamps are divided into
And a lot of light bulbs, which knocks off the buyer's pantle in the lighting store, is divided into the following types:
incandescent lamp
Halogen lamps
Energy saving lamp
luminescent lamp
Fluorescent lamp
LED LED lamp.
Any specialist will tell you that the most important difference between different types of lamps - in the way to create light flows. The most common - incandescent bulbs, but recently the interest of buyers is shifted towards halogen and luminescent. Sometimes (recently, more and more) the choice falls on a fluorescent and LED lamp. Such unsolved types of lamps are used for specific purposes: illumination of hard-to-reach places, decorating an interior element. To select a lamp correctly, you need to understand the destination. For which it is necessary and where will be applied.
Incandescent lamp. So far the most common choice
Such a lamp still remains a leader in the choice of most buyers who do not have a significant effectiveness and shortcomings of the invention. So, the usual device has not yet terrible competitive analogues - luminescent and LED lamps.
The popularity of these light bulbs is due to the low cost and ease of operation, because replacing the lamp that has failed to even children. In addition, incandescent lamps do not require voltage stability, as well as fill the room flows of light yellow shades.
Flows of light in these lamps are created by passing electricity through small tungsten threads.
Manufacturers do not sleep and today the bulbs are produced by the usual forms of pears, forms of candles, miniature and overalls.
Characteristic features of light bulbs are low levels of light losses: with 100% of the energy produced, 95% of heat energy and 5% light outputs occurs. In addition, the life of incandescent lamps are limited - small loads are killed for half a year.
Where can the incandescent lamp be applied? Apartments, offices, warehouses - incandescent lamp is good in everyday application. Installing around mirrors, people provide naturalness to illumination for applying makeup or conducting hygienic procedures.
Covering shelves cabinets better with tubular lamps. In addition, it is better not to choose these light bulbs for lighting rooms of large areas - light bulbs emit heat (95% of 100% energy), so many lamps will lead to overheating of the room.
Generation change - halogen lamps
By changing and improving the existing work and design, the era of halogen lamps began. By type of precursors, halogen produces heat and light.
The distinction of halogen lamps acts heating spirals to higher temperatures and allocation of more light flows. In addition, halogen - low-voltage, have compact dimensions, durability and economics, radiate white light.
However, halogen lamps, unfortunately, are imperfect. The heating temperature reaches 500 ° C, so before installing these light sources, it is better to check the fire safety of the room and lighting devices. Also, halogen is sensitive to changes in the voltage of the main grid, which requires the use of voltage stabilizers. Do not touch the bulb with a bare hand - there is a risk of explosion of a lamp while turning on.
Scope of halogen light bulbs, as in precursors, unlimited. Compactivity allows you to use in suspended ceilings, and a white warm light flux regulates the color gamma of interiors. Light beams of halogen gives intensity by surrounding colors. Metal, glass and chrome products acquire additional glow, so halogen is popular for highlighting shops, restaurants and sites.
Energy saving lamps - trends in savings
Save electricity is useful, and in the field of production of light sources is also fashionable. Firms manufacturers who want to meet the strict expectations of the client, produce special types of lamps - energy-saving sources of light. They create whole collections of similar products. Toaster or Steam cooker are not used as many hours a day as a light bulb in the living room or in a score on the desktop, but installing energy-saving light sources
