When purchasing lamps or chandeliers, it is important to know what types of lamps the lighting device is designed for. Modern manufacturers make products even for exotic types of light bulbs, which are very difficult to buy in Russia. The most popular is E27 (bulb). Let's find out what it is, what types of these products are, and also what technical characteristics they have.
E27 base
The base is the metal part of the light bulb. The letter "E" denotes a traditional threaded element. These products are called Edison lamps. He was the developer. E27 is a lamp that is widely used in homes and offices. Such products can be of various types and shapes.
LED models, energy-saving, halogen and others are made with a similar base. Under this lamp produce a huge number of different household lighting fixtures. These are a variety of chandeliers, decorative lamps and other equipment.
Classification
Because E27 is a bulb that can bemade in various shapes and types, it is worth considering these models. There are many types of these elements. We will study each species separately.
Traditional incandescent bulb
This is probably the most massive detail among all existing species. This product has become popular due to its ultra-low price, simple design. In addition, this solution is the most familiar. The E27 incandescent lamp is widely used in a wide variety of lighting applications. Despite such great fame and popularity all over the world, this model is significantly inferior in terms of performance and service life to its more technologically advanced "relatives". The tungsten filament often burns out - its service life ends. Also, during operation, the lamp bulb becomes cloudy. Special pairs are formed, which are the cause of turbidity. Brightness characteristics decrease over time.
There are also reflex models of incandescent lamps. They differ from a simple product by a special surface. A thin layer of silver is applied to the glass coating. This makes it possible to direct the glow to the desired point or direction. These solutions are used in cases where directional light is needed. Reflector lamps with an E27 base can be purchased in stores, they are designated R50, R63, R80. The numbers in these designations indicate the diameter of the flask. These products are also available in various forms. These are the traditional bulb, E27 bulb, candle and others.
These products have a color rendering index of 90%. The main tone, which significantly predominates in the entire spectrum of light, is yellow. That is why the luminous flux is very similar to sunlight. The service life is not more than 1000 hours.
Halogen
E27 halogen bulbs have the same threaded base. They are easily installed in traditional cartridges that are in every apartment. These models are made using a different technology, and their service life is significantly different from analogues. By the way, incandescent lamps are also popular due to the ratio of price and quality. Halogen products can burn for 4000 hours. As for the color rendering indexes in the luminous flux, it is equal to 100%.
In the technological processes for the production of halogen lamps, a little iodine or bromine is provided. These ingredients help to get the best light output. It corresponds to 20-30 lumens per watt. At the same time, such a high level of light output will be maintained throughout the entire service life of the product. Such elements, unlike incandescent lamps, are made in smaller sizes. The form can be varied. There are many ways to use these products.
Energy saving
Often referred to as small fluorescent light bulbs. These products have earned great popularity among the population of Russia and the whole world because they do not require a large amount of electrical energy to work. They became very relevant when electricity prices became prohibitive. And indeed - the counter practically does not rotate, and the light is very bright. E27-a lamp that is installed in any cartridge in a modern apartment. You can buy products at any hardware store or supermarket.
With the help of innovative technologies that are used in the production of light bulbs, these solutions are compact in size. There is a wide range of power and shapes available. What really remains unchanged in the case of an energy-saving product is durability and efficiency. In order for the lamp to serve as long as possible, you should not turn it on in vain. It is believed that frequent on / off cycles reduce the life of these products.
LED
The E27 LED Bulb is the next step in saving energy. Compared to analogues, it helps to save up to 75% of electrical energy, and energy-saving - 12% savings. These figures are quite significant in the current conditions. LED solutions are very popular. And it's not just a good opportunity to save money. The light from them is of better quality than any other. With the help of these products, you can not only solve the problem of light. They are often purchased to create coziness in rooms, as well as for decorating tasks.
With the right selection, the E27 LED lamp, which can be conveniently installed in any standard socket, can add certain notes to the interior. Due to this property, such elements are used not only in everyday life for lighting, but also in restaurant halls. To save money, they are also installed at various enterprises, inoffice space and commercial companies.
Dimmable lamps
This is one of the subspecies of the LED lamp. Previously, they were released without this feature. The dimmable lamp allows you to change the brightness of the glow. This light source is doubly economical, but also convenient. So, the E27 15W LED lamp actually consumes only 5W if you buy a high-quality branded model. Chinese products may well consume more than 15W.
Other advantages of LED products
Savings, the ability to use in interior design and the dimming function are not all the advantages of these products. Additional pluses include the fact that such a lamp very quickly enters its operating modes. A few fractions of seconds are enough for it to light up - the human eye does not notice this time, and an instantaneous flash effect is created. Also, a huge service life can be added to the number of advantages. Various manufacturers who make quality products guarantee a life of more than 50,000 hours. No other lamp is able to show even something close to this result.
LEDs do not perceive interruptions in the supply of electricity and are not demanding on the quality of the voltage. The fluctuations that often happen in large and not very large cities are not terrible for them. Also, the advantages of these solutions include high environmental safety. During the operation of the LEDs, they do not heat up and do not emit harmful substances into the air. These lamps are ideal for apartments and houses where there are small children orPets. And finally, one more argument is a very pleasant light. It does not pulsate or flicker, as is the case with a conventional incandescent lamp. This is very good for the human eye. The disadvantages include the high cost of the product and the high prevalence of fakes. If you buy Philips E27 lamps, they will fully serve their life and help save a lot.
Specifications
The most important characteristic is the luminous flux emitted by this or that lamp. It is measured in lumens. Previously, almost no one used this parameter, and power was considered the main characteristic. Now even a Chinese LED product consumes 10 times less. On average, an incandescent lamp produced a flux of 12-14 lumens per watt. With new LED solutions, the luminous flux can range from 80 to 190 lm. Flicker factor is an important characteristic. In the case of conventional lamps, this parameter remains unchanged. Most manufacturers do not indicate it - branded products are doing well with this. But for Chinese "know names", which are most often bought, a different picture emerges with flicker.
Also an important characteristic is the level of protection. There are protection against water, dust, exposure to humidity. Usually these parameters are indicated on the packaging. The fact is that for each manufacturer, these parameters can vary significantly. As for the operating voltage, the modern manufacturer offers products for 12 or E27 LED lamps220V. In Russian stores, they are most often designed for a voltage of 220 V. Models for 12 V are intended for the European market.
Result
The E27 bulb is the standard for most lighting fixtures that are used not only in everyday life, but also in production. There are many products created by different technologies with good efficiency and economy. Choosing the right option now is not difficult. Such solutions, if properly selected, will last a very long time, while saving you money on electricity consumption.
