The principle of a nail lamp (also known as a Gel lamp) is to emit ultraviolet light (UVA, UVB) to cure liquid Gel into a solid. Higher wattage appears to cure faster, but in reality, it can easily cause the Gel to overheat and burn fingers. Nail lamps do not require excessively high power; the models we provide set the illumination time to 30-60 seconds to reduce the risk of Gel overheating due to high power. Additionally, slower curing allows the Gel to become harder and denser. There is no longer a need to distinguish that LED lamps are only suitable for hard Gel or soft Gel; every lamp from our company can fully cure all nail Gels.
