AtBuying lamp is important to know what type of lamp is suitable for him, because in most cases, supplied with lighting fixtures, it is not included.Today in the shops lamps presented in a large assortment.They differ in shape, size, power consumption and the cap.Cap - a portion of the light bulb, which allows you to attach it to the lamp holder, and through which a current is applied.
plinths are made of metal or ceramic.Inside they are filled with electrodes (the lamp part) and externally have contacts.Each lamp uses a specific cartridge, which is installed in a lamp with a suitable cap.Before buying a chandelier it is important to know what type of cartridge is suitable for it, and accordingly, and which lamp.
It is important to choose the right lamp for lighting
In addition, the lamp has to be replaced periodically because they are not durable.To ma
What are the caps
Due to the variety of well-known today, caps, was developed a classification, according to which all kinds of lamp base can be divided into groups.Among the most common are considered two groups and the threaded pin.
traditionally considered the threaded cap, or as it is called - a spiral.It is denoted by Latin letter E. screw caps are widely used for many kinds of lamps, including for the household.For the letter, as a rule, it is a figure, it shows the thread diameter.The most common screw caps are marked E14 and E27.For high-power lamps and sockets exist, such as E40.
Slightly less popular are pin base, it is designated by the letter G, which shows the gap between the contacts in millimeters.Scope of the pin base and wide - suitable for many lamp: halogen, fluorescent and incandescent lamps common.
Besides the traditional, there are several types of caps, which are less common, but, nevertheless, are used for different types of lamps.
- base with recessed terminal (R).They are mainly used for devices with a high intensity, which operate on AC.
- pin (B).Allows you to quickly replace the lamp cartridge due to asymmetrical lateral contacts.They are sophisticated analogue screw caps.
- With one pin (F).Such caps are three subspecies: cylindrical, grooved and special shape.
- soffit (S).The most common light bulbs with the cap used in hotels and cars.Their distinguishing feature - a bilateral arrangement of contacts.
- Fixing (P).Scope - special lights and spotlights.
- Phone (T).They are equipped with remote control light bulbs, lighting, signal lamp shields automation.
often marking lamp consists of more than one letter.The second letter usually indicates a subspecies of the fixture:
- V - socket with a tapered end
- U - energy saving
- A - Car.

It's aboutthe most common lighting lamps, those that are commonly used in domestic and industrial premises.These include incandescent, halogen, energy-saving fluorescent and LED.
is considered the most mass of all kinds of lamps and probably familiar to everyone.It has gained popularity due to its low cost, ease of construction and familiarity.Used in the most simple models of lamps.However, despite the wide popularity, incandescent inferior to their specifications, "brothers."Its lifetime is about 1,000 hours, but it is not the most serious drawback.The fact is that during operation the lamp pairs are produced which provoke turbidity flask, so brightness decreases with time.The color rendering index is about 90%.The predominant tones in the spectrum are the yellow glow, so the light from conventional incandescent lamp reminds sunny.Most, if not all incandescent lamps are available with E14 and E27 caps.
There reflector bulb.Their main and the only difference from simple lamps - silvered surface.This helps to direct the light to a certain point, however, such lamps are used to produce directed light.In stores you can find reflector lamps with the designation R50, R63 and R80, where the number - the diameter of the lamp.Also, as with ordinary incandescent lamps, reflector is provided in the threaded socket E14 or E27.
able to serve four times longer than an incandescent lamp.The period of her life is about 4000 hours.The color rendering index - 100%.Manufacturing Process halogen lamps involves adding an amount of iodine or bromine.This contributes to a better light output, which is 20-30 Lumina / watt.And consistently high light output is maintained over the life of the operation and is not reduced as a conventional incandescent bulbs.
Being smaller in size than conventional lamps, they form a more varied accordingly wider application areas.Socles they may be as follows: G9, G4, R7S, GU10.
This term is usually used when talking about a small fluorescent lamp.These bulbs have gained extraordinary popularity due to the fact that they are able to reduce energy costs.They are sold everywhere, and set them in place of the old incandescent bulbs is not a problem, because it does not require any alterations.
With the latest production technologies, energy-saving lamps have a compact size, a variety of power options, a variety of forms, but always a long service life and efficiency.However, it is important to remember that these lights "do not like" frequent switching on and off.It argued that it shortens their lives.
They are sometimes called tubular or linear because of the characteristic shape.The letter T indicates the tube diameter and the number following it - the diameter in inches (Eighth parts).For example, T12 (12/8 inch diameter = 3.8 cm).
Socles fluorescent lamps
They also apply the term "energy saving", but this is not their main advantage.The main thing - an incredibly long life, which is from 25 000 to 100 000 hours.If we translate this number in years, you get 3-12 years of continuous operation.The light output is almost one hundred percent.
In addition, LEDs do not heat up substantially, so these lamps should be used in rooms where the temperature regime is strictly observed.Normal cap is subject to the application of LED lamps.
