starlight sler® - cordless LED curing lamp for a better curing result sler® stands for „soft light energy release”, a slow decrease of light intensity at the end of the cycle. This patented mectron technology modulates and controls the temperature and shrinkage of the composite, improving its mechanical properties. for flexible use Polymerization with more than 1.400 mW/cm2. The powerful and long lasting lithium-ion battery allows up to 320 cycles without charging. Recharching takes only 90 min. The battery can be simply unscrewed.
