It is often used to charge various gadgets as a replacement for power supply through a standard outlet.

Convenience. Using such a device is simple and straightforward. To make it easier to direct the artificial light source, you can choose a model with a flexible stem. This will direct the light beam in any direction. With such a device, you can work fruitfully at any time of the day without causing discomfort to others

Price. The cost of a USB lamp is affordable. This also played an important role in the popularity of this product. The lamp will cost much less than a regular table lamp, and the quality of its lighting is just as good. But do not forget that there are less and more powerful devices on the market

Varieties

Various types of lamps are used in the production of compact luminaires. Most often, manufacturers use light-emitting diodes (LED). This is the most profitable and practical option. Also on sale are models with halogen or fluorescent bulbs.

Halogen. It should be noted that finger lamps are rarely used. Due to the high energy consumption, manufacturing firms refuse to use them, opting for more advanced technologies. These products have never been in great demand in the domestic market, especially now, when more practical options have appeared

Luminescent. Luminescent versions also heat up in a similar way to halogen ones, but they consume much less electricity, which is very important for compact gadgets. Their main disadvantage is that it is highly sensitive to fluctuations in the power grid. Some lamps may burn out a couple of days after purchase if the equipment is not able to provide an even flow of electricity without surges

LED. The model of a lamp based on LED technology has a longer service life compared to analogues. They have a number of advantages: low power consumption, light weight, favorable price. It is these models that are more often found in theme stores. LEDs shine brightly and even a small light bulb may well be enough to illuminate the work surface

This technology is actively used due to the fact that even with a low power of 5 W, the diode can shine quite brightly. In addition, power drops are not terrible for them.

Constructions

Manufacturing companies claim that all USB lamps available on the market can be divided into 2 groups - with and without a stand.

Stand models are larger. In addition to the cord that connects to the PC, the luminaire is equipped with a special platform. As a rule, there are two buttons on the device. One to turn on the main light and the other to activate the stand backlight. The developers report that using this gadget, you can comfortably work in a dark room without using additional lighting sources.

Options without stand are more compact, due to which they weigh less. The light source is mounted on a flexible tube that allows you to direct the light wherever you want.Luminaires with a long transparent tube are also on sale. Lamps without a stand are most often bought by users who choose a gadget for use on the road.

Choosing the right

When buying a luminaire powered by a USB connector, you need to pay attention to certain aspects. The first thing to note is the size and weight of the stand if the appliance is equipped with one. There are improperly designed models on store shelves when the weight of the lamp outweighs the stand. This is most often found in luminescent models. Overweight will negatively affect the stability of the lamp.

Also consider the length of the wire. They should not be less than half a meter. This is the optimal length for comfortable work.

Despite the fact that these are inexpensive products, they must also meet quality standards. The store is obliged to provide a guarantee for the product.

Leaders of sells

Given the popularity of these products, many firms that work in the field of manufacturing useful and decorative gadgets offer customers USB lamps for every taste and wallet. Among the large selection of brands, there are those that stand out in the lead. These are Xiaomi and Orient brands.

The private company Xiaomi was founded in China 7 years ago. She is engaged in the production of smartphones, laptops and various electronic gadgets. Orient is also a Chinese souvenir and USB powered firm.

Remember that the price depends on the manufacturer, the size of the device, the power, and other aspects. The minimum price is about 200-300 rubles per unit.
