Wearing armor usually requires the use of UV or LED lights for curing. Both UV lamp and LED lamp can emit ultraviolet light of specific wavelength, so that the UV glue or UV nail polish on the wearing nail can dry and harden rapidly. Which lamp to use depends on the type of glue or nail polish used. Generally, UV glue and UV nail polish need to be cured with UV light, while LED glue and LED nail polish need to be cured with LED light.

The wavelength of UV lamp is usually around 365nm, which is suitable for curing UV glue and UV nail polish containing photoinitiator. The wavelength of LED light is usually about 405nm, which is suitable for curing LED glue and LED nail polish containing corresponding photoinitiator. When using UV or LED lamps, attention should be paid to the distance and irradiation time of the lamps to ensure the curing effect. Normally, the irradiation time ranges from a few minutes to over ten minutes, depending on the product description and actual situation.
