When purchasing fixtures or chandeliers, it is important to know what types of lamps the lighting fixture is designed for. Modern manufacturers make products even for exotic types of bulbs, which are very difficult to buy in Russia. The most popular is the E27 (lamp). Let's find out what it is, what types of these products are, as well as what their technical characteristics are.
Cap E27
The base is the metal part of the bulb. The letter "E" means 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 forms.
With a similar base, LED models are made, energy-saving, halogen and others. Under this lamp, a huge number of various household lighting devices are produced. These are a variety of chandeliers, decorative lamps and other equipment.
Classification
Since the E27 is a lamp that can be made in various shapes and forms, it is worth considering these models. There are many varieties of these elements. We will study each species separately.
Traditional incandescent lamp
This is probably the most massive detail among all existing species. This product has become popular due to its ultra low price and simple construction. In addition, this solution is the most familiar. The E27 incandescent lamp is widely used in a wide variety of types of lighting products. Despite such great fame and popularity all over the world, this model is significantly inferior in terms of characteristics and service life to its more technologically advanced “relatives”. A tungsten thread often burns out - its useful life ends. Also during operation, the bulb of the lamp becomes cloudy. Special pairs form, which are the cause of turbidity. Over time, the brightness characteristics decrease.
There are reflex models of incandescent lamps. They differ from a simple product in 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 side. These solutions apply when directed light is needed. Reflector lamps with E27 socket can be purchased in stores, they are designated R50, R63, R80. The numbers in these designations indicate the diameter of the bulb. These products are also available in various forms. This is a traditional spherical bulb, E27 lamp, candle and others.
Such products have a color rendering index of 90%. The main tone, which significantly prevails 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 lamps have the same threaded socket. They are easily installed in traditional cartridges, which are in every apartment. These models are made using a different technology, and their service life is significantly different from analogues. Incidentally, incandescent lamps are also popular due to the price-quality ratio. Halogen products can burn for 4000 hours. As for the color rendering indices in the luminous flux, it is equal to 100%.
In technological processes for the production of halogen lamps , a little iodine or bromine is provided. These ingredients help you 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 remain throughout the entire service life of the product. Such elements, unlike incandescent lamps, are made in smaller sizes. The shape can be varied. There are a lot of ways to use such products.
Energy saving
Often so called small size fluorescent bulbs. These products have earned great popularity among the population of Russia and the whole world because they do not need a large amount of electric 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 can be installed in any lampholder in a modern apartment. You can buy products at any hardware store or supermarket.
Using innovative technologies that are used in the manufacture of light bulbs, these solutions are compact in size. There is a large selection of available power and shapes. What really remains unchanged in the case of an energy-efficient product is durability and efficiency. In order for the lamp to serve as long as possible, do not turn it on in vain. It is believed that frequent on / off cycles reduce the life of these products.
LED
The E27 LED lamp is the next step towards energy savings. Compared to analogs, it helps to save up to 75% of electric energy, and energy-saving - 12% savings. These figures are quite substantial in the current conditions. LED solutions are very popular. And it's not just a good opportunity to save. The light from them is better than any other. Using these products can not only solve the problem of light. They are often purchased to create comfort in the premises, as well as for decoration tasks.
With the right selection, the E27 LED lamp, which is conveniently installed in any standard lampholder, 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, in office premises and commercial companies.
Dimming lamps
This is one of the subspecies of the LED lamp. Previously, they were released without this feature. Dimmable lamp allows you to change the brightness of the glow. This light source is doubly economical and also convenient. So, the E27 15W LED lamp actually consumes only 5W in case of buying a high-quality branded model. Chinese products may well consume more than 15W.
Other advantages of LED products
Savings, the possibility of use in interior design and the dimming function are not all the advantages of these products. Additional advantages include the fact that such a lamp very quickly enters its operating modes. A few fractions of a second are enough to light up - the human eye does not notice this time, and an instant flash effect is created. Also, you can add a huge service life to the benefits. Various manufacturers who produce quality products guarantee a life of more than 50,000 hours. No other lamp can show even something close to this result.
LEDs do not perceive power outages and are not demanding on voltage quality. Swings that often occur in large and not very cities, they are not afraid of. Also, the advantages of these solutions include high environmental safety. During 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 or pets. And finally, another argument is a very pleasant light. It does not pulsate and does not flicker, as is the case with a conventional incandescent lamp. It 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 last their life and help to save significantly.
Specifications
The most important characteristic is the light flux that a particular lamp emits. Measure it 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 gave out a flow of 12-14 Lm per watt. With new LED solutions, the luminous flux can range from 80 to 190 Lm. Flicker coefficient is an important feature. 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 the Chinese "know-names", which most often buy, a different picture develops with a flicker.
Also an important feature is the level of protection. There are protection against water, dust, moisture. Typically, these parameters are indicated on the package. 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 LED- lamps E27 220V. In Russian stores, they are most often designed for a voltage of 220 V. 12 V models are designed for the European market.
Total
The E27 bulb is the standard for most lighting products that are used not only in everyday life, but also in production. There are many products created using different technologies with good efficiency and level of economy. Choose the right option now is not difficult. Such solutions, if properly selected, will last a very long time, while saving your money on electricity consumption.
