With 30 precision-placed LED bulbs, it guarantees flawless, even curing with zero dead-zones- even on the longest nails. The all-new intermittent Flash Cure Mode uses controlled light intervals to gently pre-cure gel in stages, allowing for gradual, even cure that minimizes heat spikes and discomfort, great for builder gel, rubber base, and gel polish. Meanwhile, 400 nm precision wavelength technology ensures consistent, effective curing for all gel formulas. Built for unmatched power and mobility, its cordless, rechargeable system gives you total freedom, while the sleek matte, acetone-resistant finish keeps your set up looking pristine, and the softer beeping creates a more pleasant salon environment. Completely redesigned. Fully re-enginereed. The future of LED is going Beyond Pro!
