Power, measured in Watt (W), is the most important feature in a nail lamp. It determines the intensity of the radiation and, consequently, the speed and effectiveness of the polymerization (drying) of materials (semi-permanent polish, gel, acrygel).

The type of lamp determines the lighting technology used for curing.

UV Lamp: Uses fluorescent bulbs that need to be replaced after a certain number of hours of use. 

LED Lamp: Uses LED bulbs (light-emitting diodes) that have a long lifespan (up to 50,000 hours).

UV/LED Lamp: Combines both technologies, emitting light at dual wavelengths (365nm & 405nm). This allows it to cure all semi-permanent polishes, UV gels, builder gels, polygel, and acrygel.

Offers flexibility and ergonomics, making it easier to work in different positions or angles and easier cleaning since each part can be cleaned separately. Facilitates use for pedicure as it allows the lamp to be placed over the foot without obstruction from the bottom part.
