It's hard to imagine what the modern world would look like without electric light bulbs. Manufacturers produce a wide variety of lamps. However, you should know that not everyone is the same. When buying, it is important to know what size the lamp base has, otherwise the purchased copy may simply not fit, and you will need to purchase another lighting fixture of a suitable size. Please read our article carefully to avoid wasted purchases in the future.
Types of plinths
Standard lamp base is marked with a letter and numbers. What do they mean? The letter denotes the variety, and the number characterizes the type. The most common base today, marked with the letter "E", was invented by Edison. They call it the "Edison Screw type". The number following the letter indicates the diameter. The most common plinth size today is 27 mm.
In terms of popularity, "minions" - "E14" are on the honorable second place. This size lamp base is commonly used in sconces and small fixtures. Although manufacturers are willing to use them in large chandeliers.
Socles of incandescent lamps type "E" are also available with original markings 5, 10, 12, 17, 26 and 40 mm in diameter. However, in everyday life their prevalence is low.
In today's world, energy-saving technologies are becoming more and more popular. Manufacturers of lighting fixtures did not stand aside either. Today, many kinds of energy-saving light bulbs are produced with socles of the "E27" type, as well as "E14". However, you should be aware that they are not suitable for electronic switches. Also, such lamps are not suitable for working with circuits where conventional dimmers are used.
Pin sockets
The difference between this type of socles and the previous one is the pin system for attaching the lamp to the socket. Such a base is designated by the letter "G". The next number indicates the distance between the middle of the pins. Such a connection is used in fluorescent, as well as in halogen lighting fixtures. The dimensions of the bases of lamps of this type may vary. Halogen lamps are equipped with lighting fixtures marked "G4" and "G9". Other bases of this type are used in fluorescent lamps.
Marked lamp socket"GU" indicates that this appliance is energy saving. Light bulbs of this type are like a pill. This light fixture is ideal for lighting cabinets, for decorating small interior items, as well as for suspended ceilings.
Plinth "R7s-7"
This type of base has a recessed contact. The main representatives of lighting fixtures with the "R7s-7" base are halogen quartz lamps. Their main area of application is high-intensity lighting installations.
For the sake of completeness, mention should also be made of lamps with a pin base type "B", which is quite rare. Manufacturers also produce lighting fixtures with the "S" soffit base, as well as with the original "P" focusing base. Usually these are lamps of an unusual design, but they are hardly used in everyday life.
