Lamps that emit UV rays are used to dry nails. Only with their help can you dry gel polish. The remaining liquids dry in the air due to the evaporation of moisture. Shellac does not have this property, so it dries only under the influence of UV rays.
Craftsmen cannot always figure out which lamp is better: Ice or UV, since they have few differences. The main difference between them is the principle of operation of the devices. Led devices also operate in the UV spectrum, but powerful SMD LEDs are installed here.
What is an LED lamp
At first glance, it is difficult to understand how an LED lamp differs from a standard UV lamp for nails, since they are assembled from almost the same components. The main difference is the elements that are used as a radiation source. There are 2 types of LED devices:
- indirect lighting. In this case, the light from the chips is reflected an infinite number of times from the vertical walls, which creates an intense glow. This type of design is used to create powerful devices;
- localized lighting. Here the stream of light is directed to one place where the hand is placed to dry the nails.

Based on power, LED lamps are divided into 3 types:
- 45 W – high class. They are bought by professionals to work in salons;
- 18 W – middle class. Purchased for drying nails at home;
- 9 W. For personal use only.

Studying the reviews, you can see that LED lamps for drying gel polish have practically no disadvantages. One of the disadvantages is UV radiation in a narrow wavelength range. Also, some complain about the high price compared to competitors, but this lamp will last much longer.
Among the advantages are the following:
- SMD diodes provide fast drying. For example, a mid-range device will dry the varnish in about half a minute, while a fluorescent lamp will take about 2 minutes;
- The light emitted by LEDs is harmless to humans. The lamp may be disposed of together with household waste;
- service life - 50,000 hours, that is, 5-6 years.
- LED products consume much less energy compared to their fluorescent counterparts;
- During operation, the diodes do not heat up, so the nail plate will also not suffer from overheating.
Polymer and photoinitiator
The main subject to consider is the polymer or photoinitiator. Its basis consists of active chemical elements that are activated under the influence of light rays and react. It breaks down the polymer, converting it into new solid molecular compounds.
In order to decide on the choice of lamp, you need to know a few simple things:
- Properties and composition of varnishes.
- Technical characteristics and interaction with nail polish of lamps for drying nails.
What is a UV lamp
The UV lamp is equipped with fluorescent tubes that emit ultraviolet light, which affects the nail polish. This type of dryer appeared before LED devices, but still sells well to this day. The device consists of a control panel, timer and fan. The power of these lamps is as follows:
- 9 W. Suitable for home use;
- 36 W. Provides fast drying of varnish, therefore it is often used by professionals;
- 54 W. Maximum power. Models have a built-in fan to protect against overheating.

Fluorescent light bulbs have a wide spectrum of radiation. Thanks to this, they can be used to dry not only gel polish, but also hard gel, bio and regular polish. Also, UV devices are not as expensive as their LED counterparts. One of the significant disadvantages is the possible damage to the nail plate when using a high-power device due to overheating.
Fig.5 – relative spectral power distribution.
If you work with a low-power device, you should be prepared for the drying time to increase. Also, fluorescent light sources gradually lose their emission power, so manufacturers recommend changing the device every 3-6 months. Moreover, these devices are unsafe: if the lamp ruptures, toxic mercury vapor will be released. Shelf life – up to 3000 hours.
What is the difference between an LED lamp and a UV lamp for nails?
Before purchasing a high-quality device for drying gel polish, you need to understand the difference between an Ice lamp and a UV lamp. The main difference is the light source. In a UV device, a fluorescent light bulb is used for this, and in an LED device, an LED is used. The latter has a high service resource. But occasionally the chips can burn out, which is why the lamp has to be sent in for repair.

Ice devices dry varnish much faster. This will take no more than 40 seconds. But not all types of varnish harden under their influence, since shellac begins to harden only under ultraviolet rays. The wavelength range of LED products is smaller, so the varnish may harden unevenly or not at all if a cheap model is used.
Speaking about low power UV lamps (up to 18 W), it is worth noting that they dry the varnish slowly. In some cases, the lower layers may not dry completely. This destroys the nail coating within a few days. The best options are professional models with a power of 36 W or more.
Also, during the selection process, it is worth considering that the UV lamp is harmful to the body, and the LED device does not cope with all types of varnish. Therefore, experts advise buying combined models, for example, LED-gas light. Using these devices you can work with any type of polymer, and drying will last a maximum of 2 minutes. The disadvantage of such models is their high price.
The essence of the procedure
When the device is turned on, ultraviolet rays begin to be produced. Their impact kills fungus, viruses, bacteria and other harmful microorganisms living in the room. The surrounding space becomes almost sterile. In apartments, “domesticated” types of such devices are used, the degree of radiation in which is minimized. Children's rooms are often treated.
The quartz installed in the device produces a large amount of ozone into the environment - enriching the air with such an element becomes especially relevant during the cold season. Of course, such artificial ultraviolet light cannot completely replace sunlight, but periodic use of the device strengthens the body, improves immunity, and ensures the production of vitamin D and other biologically active substances. We can say that the lack of sunlight is compensated. But the bonuses from using the device are not only this.
Which lamp is better and dries gel polish and shellac on nails faster?
When using an LED lamp, the average drying time for nail polish is from 20 seconds to 2 minutes. To ensure that the polymer dries completely and evenly, it is recommended to purchase models in which diodes are located over the entire surface inside the device, and not just on top. Speaking of luminescent analogues, the drying time of shellac completely depends on the power of a particular model.

If you use a lamp with a power of up to 18 W, drying will take 3 minutes. The best option is considered to be hybrid models with a combination of LED and gas lighting technologies. The main advantage is that these devices allow you to work with different types of gels. It takes 20-30 seconds to fix the varnish.
Which light bulbs are not harmful to the eyes?
The most acceptable light for the eye

The best lamp manufacturers
When choosing a UV lamp or an Ice lamp, you should understand the difference between them, and also understand the quality of the devices. It is not recommended to buy cheap Chinese products, as their work can negatively affect not only the quality of drying, but also the health of your hands. After some time, your nails may crack, as will the polish itself immediately after drying.

Regardless of the type of lamp, when choosing a model, you need to take into account the power, the presence of a timer, the type of beams, the design, the presence of a removable bottom and a fan if the device has fluorescent light bulbs.
Additional functions
Depending on the manufacturer and model, the LED manicure device includes additional functions:
Timer
LED drying devices with a timer allow the master not to focus on time - the lamp itself will inform you when drying is finished by sounding a beep or turning off the light inside. Usually the timer is programmed for 15,30 and 60 seconds, but there are manufacturers whose devices have a different step
For example, Kodi programmed their dryer for 30, 60 and 90 seconds.
Display. The drying time is displayed on a small screen, which serves as an additional reference point for control.
Bottom. Externally, nail dryers differ in design and the presence of a bottom. There are devices with a familiar design - cases with a bottom, inside of which diodes and lamps without a bottom are installed - in this case, the hands are placed on the manicure table.
Sensor. Sensor devices do not allow you to start the lamp manually - they do it automatically when you place your hand in the glow area. Several devices with touch control are presented by the SUN brand, for example the LED lamp 54 w SUN5 plus.
