The SUNUV SUN7 is a 48W UV LED nail lamp designed for curing all types of gel nail polish. It features 30 UVLED combined light beads for efficient curing. This smart nail lamp has an auto-sensor for hands-free operation, a 99-second low heat mode for comfortable curing, and a Double Power button for significantly faster curing speeds (up to 2x faster). The large LCD screen displays curing time. Its compact and enclosed design prevents light leakage, protecting your eyes. The lamp is suitable for both salon and home use, with a larger body that can accommodate 5 fingernails or toenails at once. The 30 long-lasting LED beads (50,000 hours lifetime) are evenly distributed for uniform curing. It includes 4 timer settings (10s, 30s, 60s, and 99s low heat mode/double power) with a time memory function, allowing you to select the appropriate cure time based on salon needs and gel polish requirements.
