Which lamps to choose: halogen or LED? Millions of people around the world are trying to get an answer to this question. Both types are very popular not only among ordinary consumers, but also among motorists. LED lamps are used in almost all light sources. The degree of demand for halogen analogues is also high. But the difference between halogen and LED lamps is obvious. Each type has its own characteristics, has its own principle of operation. What is the difference between LED lamps and halogen lamps and which products are better to use?
More about the operation of halogen light sources
Before you understand which is better, halogen or LED lamps, it is worth considering the features of both.
The design of halogen samples largely repeats the design of conventional incandescent lamps. The only significant difference is the presence of halogen in the cavity of the flask: iodine or bromine. It is necessary in order to increase the life of the lighting fixture.two or even four times.
When turned on, the filament heats up to the required temperature and begins to emit light. During this process, tungsten is released from the surface of the helix. Small particles of the released substance react with the halogen, which prevents the deposition of tungsten atoms on the inner surface of the flask.
As a result, a kind of positive feedback is created around the luminous thread, which contributes to an increase in the temperature of the spiral and an increase in the brightness of the illumination. The maximum temperature can be three thousand Kelvin. The shape of halogen lamps can be different. It all depends on the area of application. On the shelves of stores you can find halogen lamps for use in medicine, household appliances and cars.
Pros and cons
The demand for halogen lamps is due to the advantages of these light sources:
- replacement does not require much time and effort;
- they emit warm tones that are reminiscent of sunlight;
- low cost provides accessibility to the absolute majority of buyers.
Due to the low cost, production and consumption of halogen lamps remains at a high level. Due to their compactness and resistance to voltage drops, they are actively used in car headlights.
The disadvantages of halogen lamps include low efficiency, which does not exceed 15%. This is due to the fact that most of the energy consumed is spentto maintain heat. The duration of operation is relatively short, averaging about two thousand hours. This indicator directly depends on the frequency of switching on the lamp and jumps in the network. In order to extend the life of halogen lamps, some consumers are forced to install switches with dimmers that provide a soft start.
More about LED lamps
An LED lamp is a ready-made device, the components of which are a light source and a driver. Currently, a lot of white LEDs have appeared on store shelves, the cost of which is quite low. This led to a sharp reduction in the cost of the production process, made it possible for a wide range of people to purchase the device.
LED lamps are widely used not only in household appliances, but also serve as the basis for garlands and traffic lights. Experts advise putting them in children's toys and the dashboard in a car. Glowing strips based on LEDs emphasize the style of the interior in homes and offices. LED lamps are currently a serious competitor to xenon in car headlights. The popularity of devices is due to their reliability, which is confirmed by seven-segment indicators. The service life of the latter is 5 years or more.
The main advantages and disadvantages of LED lamps
The demand for LED lamps is due to their excellent functionality and a number of othersmerits. Lamp life with built-in primitive driver is about 36 hours. The service life of higher quality models with expensive components can reach 72 hours. The efficiency of LED lamps is much higher than that of halogen counterparts, and is 30%. That is why experts advise buying them.
A huge advantage is also the instant on and off LED lamps. This is especially important in dynamic installations. The small size of the constituent elements allows you to create lamps of any shape. In addition, they can be handed over for repair in case of problems. This greatly increases the service life.
Another advantage is the relatively low temperature and the absence of harmful components and radiation. According to professionals, the last two factors ensure safety and do not have a detrimental effect on the human body. In addition, LED-based lamps can be produced with both glass and plastic bulbs.
LED lamps also have disadvantages. One of the main disadvantages is the high cost of products whose power exceeds 5 watts. Here it is worth noting several main points that prevent widespread distribution: the high price of products based on LEDs with a power of more than 5 watts. This does not allow such devices to be widely used in car headlights, searchlights and street lamps. In addition, LED lamps can only be used withspecial driver.
Cost
The determining factor for many people is the price of appliances. That is why, before answering the question of which is better, halogen or LED lamps, you need to consider the price categories to which the products belong.
The cost of LED lamps is much higher than that of halogen lamps. You can buy a device of the first category with a standard E27 base for an average of 150–350 rubles. The price of halogen lamps does not exceed 50-60 rubles. Please note that the shelf life is different for halogen and LED lamps.
Which is better?
Both types of lighting fixtures are popular. But many people are still interested in which is better: halogen or LED lamps? Having analyzed the features of the work of both of them, having studied other nuances, you can give an unambiguous answer.
LED lamps have only one drawback compared to halogen counterparts - high cost. But can the price be considered a minus? After all, the working life of LED-lamps is about 30 hours. While the same indicator for products with halogens is much less. And this means that during the operation the cost of LEDs fully pays off. Experts recommend not discounting this version of lighting fixtures also because the manufacturer gives a guarantee on the lamps. If the product stops working before the expiration of the warranty period, the lamp can be returned to the store or exchanged for a similarcommodity.
Furthermore, LED lamps are much cooler and can have a plastic housing that has shock-resistant properties. No halogen device can give such results.
Conclusion
The question of which is better, halogen or LED lamps to use in lighting devices, worries millions of people around the world. Both light sources are in demand. However, a comparison of halogen and LED lamps demonstrates a clear superiority of the second option over its counterparts. It is LEDs that are recommended to be purchased by specialists who know firsthand about the characteristics of lighting devices.
