LED lamps with E27 base: overview and comparison of the best options on the market

Selection by prices and manufacturers

Many consumers are convinced that the price tag for LED lamps from well-known manufacturers is not justifiably high and it makes no sense to make a choice in their favor, since there are cheaper Chinese counterparts. However, everything is not so clear-cut here.

Expensive or cheap?

So which LED lamps are better - cheap or expensive? To answer it, we need to consider both groups separately.

Cheap lamps from China are often low-quality products. But the low price is a very tempting indicator, so Chinese LED lamps are in great demand. We list the main disadvantages of cheap Chinese LED lamps:

• the packaging indicates overestimated specifications;
• the warranty period is short or non-existent;
• the assembly uses low quality parts;
• as a rule, the real color rendering index is less than 75 CRI;
• the driver for the LEDs is either absent or provides unstable power, thereby causing a high pulsation of the light flux;
• an inefficient heat dissipation system is used.

You should not believe the numerous positive reviews on the Internet about a cheap Chinese product and choose a product according to this criterion. Some of these reviews are simply ordered and deliberately false. And the other part was written by people who are ready to put a plus only for the fact of the timely delivery of the goods or for the fact that the goods are in working condition. As a rule, we are not talking about technical characteristics and their compliance with the declared indicators.

Reliable manufacturers

Over the past years, some of the highest quality LED lamps have been produced in Europe and Japan. Their price is higher than that of cheap Chinese counterparts, but the quality is completely different. Below is a list of several brands that will help you choose products of decent quality.

• Philips;
• Osram;
• Wolta;
• Nichia.

Due to the influx of cheap Chinese products and the difficult financial situation in the country, most Russian manufacturers have significantly reduced the quality of their products. Today, there are only a few Russian brands that are still trying to please the consumer with their quality:

• X-Flash;
• Lisma;
• Navigator;
• Gauss.

Also in this list, it is worth noting the Chinese company Camelion, which has proven itself from the best side, as a separate item.

Design features

The only structural element that unites all types of lamps is the base.Otherwise, the design differences between energy-saving devices and LED devices are significant.

All such devices are divided into three types:

1. Incandescent. Warp: tungsten filament; vacuum flask, usually with an inert gas composition.
2. Gas-discharge.
3. LED.

Only gas-discharge and LED light sources are considered energy-saving.

The glow of gas-discharge lamps is realized by means of an electric discharge in metal or gas vapors. Gas dischargers can be divided into:

1. High pressure lamps. There are sodium, mercury and metal halide. This type is best suited for outdoor lighting.
2. Low pressure lamps. This type includes fluorescent light sources. The main structural element is the electrode tube, which is filled with vapors of argon gas and mercury. The inside is covered with a phosphor. For it to glow, a short-term high-voltage discharge must fall on the spiral. If there is low voltage in the house's electrical network, the lamps may light up problematically (not immediately and dimly or not at all). They are used for both indoor and outdoor lighting of a house or apartment.

When you need to choose which light bulbs are best for your home, LED or energy-saving, the latter means fluorescent devices.

A modern alternative to the types of lamps described above are LED devices. Such lighting elements, due to their design, are characterized as:

• energy saving;
• eco-friendly;
• durable, resistant to power surges.

A minor drawback is the cost of LED lamps. The technology of their production is new, has not yet been modernized, due to this it is quite expensive. The payback of one-time costs for their purchase is almost 100%, due to their durability and economy.

Design features of LED sources:

1. The principle of using the light flux. The light emitter is an LED or a group of them. Such a diode element converts electric current into light by passing current through a special crystal (semiconductor).
2. The light emitting element of the diode family processes electric current into light by passing it (current) through a semiconductor crystal. A significant advantage is that the current is passed only in the required direction.
3. The light emitter can be either in an open design or placed in a special flask.

Such light emitters are much more resistant to mechanical stress, in contrast to a similar element of fluorescent lamps (electrode tube with vapors of mercury and gas).

Differences in the design of CFL (compact fluorescent lamp) and LED light bulbs is one of the main parameters of technical and operational characteristics, which allows you to determine how they differ. Their economy is also important.

The best LED lamps of Chinese manufacturers

This is a separate category with its own pitfalls. I do not believe a single word of those who say that on Chinese sites like Ali, DX, etc. There are no normal LED light sources. I have tested and continue to test many stores from "those" places. The vast majority are outright rubbish, but there are some good ones as well. The price tag for their products is also not small, but still an order of magnitude cheaper than that of pseudo Russian manufacturers. When they ask me for advice, I always send “something cheaper” to trusted stores. But here, too, there are some nuances. This is a pulsation. Last week, I completed a project to replace the lighting of one of the housing and communal services, which wished to replace the lighting in a number of houses (entrances) with LEDs. One of the conditions was to invest in, to put it mildly, a small budget. Here and had to turn to "our brothers." From their list, the most-most suitable for the budget were selected. All were satisfied. But he warned that for such a price they would receive lamps with a pulsation, not much higher than GOST. The ripple was about 34 percent. In principle, the flicker is quite strong, but this is if you install these sources in the apartment. And for the entrance does not play a big role. We don't read in hallways

Well, if you sum up the Chinese manufacturers - handicraftsmen, then yes ... For the most part, they "drive" outright trash. And you need to be able to bypass it, and not rush even at those sellers who have very large sales.

Differences in design and principle of operation

To compare incandescent and LED lamps, it is necessary to consider the design and principle of operation of each source.

The first is a tungsten incandescent light bulb.

It is arranged as follows:

• Plinth. Needed to screw the light bulb into the socket. Usually made from aluminium.
• Flask. Production material - glass. Protects the tungsten filament from environmental influences. A vacuum is created inside or filled with an inert gas. The gas prevents the metal elements from oxidizing.
• Electrodes, hooks for holding them. These elements hold the filament.
• Incandescent thread. Made of tungsten, used to emit light.
• Stengel. It contains electrodes with hooks. He himself is at the bottom of the flask.
• Insulating material, contact surface.

The principle of operation is to conduct current through the source and heat the tungsten filament to high temperatures. As a result, it begins to emit light. The thread warms up to 3000 degrees, while not melting.

Externally, the diode bulb resembles the previous design. It also contains a plinth with a thread of the same dimensions (the markings are also the same), so there is no need to remake the equipment or fixtures under the bottom. But the difference is in a more complicated internal design:

• Contact base.
• Frame.
• Power and control board. It is necessary to prevent the lamps from burning out. They reduce the voltage, equalize the current.
• Board with LEDs.
• Ballast transformer.
• Transparent cap.

The luminous flux is formed when two substances from different materials come into contact, through which a current has been passed.The main condition is that one of the materials is charged with negative electrons, the other with positive ions.

Luminous flux and light pulsation coefficient

Measurements of the luminous flux were carried out in the photometric sphere after a mandatory warm-up lasting 60 minutes. Heating the LEDs leads to a decrease in the luminous flux, on average this figure is 5%. The reduction depends on the quality of components and build quality.

Taking into account the error of measuring instruments, the results of measurements of the light flux fit into the allowable 5%, which are acceptable in production.

Lamps 10-18W

Model	Claimed	measured
A60-101-1-4-1	950lm	905lm
A60-101-2-4-1	1500lm	1438lm
A67-101-1-6-1	1800lm	1810lm
A67-101-1-4-1	1800lm	1790lm

Lamps for 8W

Model	Claimed	measured
C37-101-1-4-1	850lm	763lm
C37-101-1-4-2	850lm	747lm
G45-101-1-4-2	850lm	780lm
CT37-101-1-4-1	850lm	752lm

All samples have a luminous flux ripple coefficient of less than 1%, which means that the installed power source copes well with the load.The spectrogram shows frequencies up to 370 Hertz, the spectrogram is smooth, without bursts at frequencies of 100 and 200 Hertz.

The samples worked without a decrease in brightness at a voltage of 130 volts, instead of the prescribed 220 volts. This is rare, most lamps from other manufacturers have a lower operating voltage of 160-170 volts and then the lamp turns off.

Decoding of marking values

For a simpler understanding of the design features and technical characteristics, all existing modifications of LED lamps are divided according to the generally accepted classification. Devices are labeled according to their intended purpose, type of base and device.

The marking is applied to the packaging in accordance with established standards. Having studied it, you can quickly get a clear idea of ​​\u200b\u200bthe capabilities of the device of interest.

The marking displays:

• power and brightness;
• maximum terms of continuous operation;
• degree of energy efficiency;
• flask variation;
• range of permissible operating temperatures;
• color quality level.

One of the main criteria that they are guided by when choosing is the type of basement.

The base is the most important part of the device, since it is responsible for the tightness of adhesion of metal contact elements and the quality of interaction with the electrical power circuit.

Any damage to the base makes the equipment sensitive to the slightest changes in current and voltage parameters. This threatens with serious interruptions in the operation of the lamp, which will soon lead to complete failure.

Soffit bases are marked with the letter "S", recessed contacts - "R", pin - "B". Devices with a standard threaded connection, characteristic of conventional incandescent lamps, are assigned the letter "E".

As a marking, such a symbol was chosen for a reason.It is borrowed from the name of the designer of the design - the famous inventor in the field of Edison lighting technology.

LED bulbs with the designation E14 are called "minions". From the common modification E27, they differ only in the dimensions of the base

The number next to the letter determines the diameter of the contacts, measured in millimeters. The connection of the bulbs in question is 14 mm.

Luminous flux: which lamps are more economical

Most consumers are guided by this criterion, making a choice in favor of fluorescent or LED lamps. To determine the difference in economy and electrical efficiency of these two types, you can compare them with respect to energy consumption and operating efficiency with traditional incandescent lamps.

The most important indicator, without which it is impossible to make such a comparison, is the luminous flux. This parameter determines how much light will be in the room of the house or apartment. It is measured in Lm (lumens; lm). The higher the luminous flux of the lamp, the brighter it will be in the room during its operation. This value may decrease over time.

Almost all manufacturers of energy-saving and LED bulbs indicate on their packages that the main operating parameters of their lamps correspond to those of incandescent lamps.

Focusing on the average values ​​of such performance characteristics of most common lamp models and manufacturers, an analysis was made of the efficiency and economy of electricity consumption in relation to the value of the luminous flux. The results of such a comparison are shown in the table.

Based on the tabular data, you can easily determine that LED bulbs are much more economical and better in terms of quality of operation compared to similar energy-saving ones.
