UV is generally emitted between 100 and 400nm, but not all gels catalyze at the same wavelength. Some gels polymerize around 350nm, while others, like Green Flash LED polish for example, will need a higher wavelength for optimal polymerization. Manucurist lamps therefore between 370 and 400nm.
Gel polishes—which require exposure to a UV or LED light to harden and dry—have been around since at least the 1980s and offer a longer-lasting, glossy finish without the regular 30-minute dry
Gel nail polish needs to be dried using either an LED or a UV lamp, whereas regular polish can air dry. Using an LED/UV lamp on regular polish will not help speed up the drying time.
