LED Lamp, Explained
Quick definition
The low-heat cure device that hardens gel polish in 30–60 seconds per layer.
LED lamps emit narrow-spectrum light matched to modern gel photoinitiators — faster and cooler than old UV tubes. Wattage matters less than wavelength matching your specific gel brand.
Under-cured gel causes allergies and lifting; always follow the polish maker's time, not the lamp's preset.
