Lower light intensity may cause insufficient adhesion of bonding material, poor polymerization of resin-based composite which may result in fracture, micro-leakage, sensitivity, and recurrent caries, unable to resist wear in function, unable to be polished, unable to maintain their luster and color. Choose a high-energy output curing light to improve Clinical Results through Light-Curing! A high light-energy device in hand is the key to ensure the quality and durability of the restorations when light-curing resin adhesives, resin-based composites, resin cements, and other light-activated restorative materials. Advantage of Rolence curing light - Ultralite 1000E: - High light intensity output up to 2,100 mW/cm2; light energy rarely declines (<50 mW/cm2 per year). - 3 seconds to cure 3-mm-thick resin composite specimen. - Autoclavable curing tip rotates 360°for curing at any position of mouth, - Versatile fiber optic curing tip optional, - 4 (four) modes preset, including cycle light for orhthodontics. - Raised and large rubber power switch for easy activating operation even wearing glove. - A working fan inside for more efficient cooling performance. - Powered by a lithium battery. Supports 400 cycles of 5 second exposure when being fully charged. - Palm-size, light-weight handpiece for comfortable hand-holding. - A perfect product for dentists with smaller hand. - A built-in light checker in the charging base
