The Light 405 operates from 405 nm ? 490 nm (peaking at 460 nm) to meet all standard light curing needs. The light intensity per mode is: High mode: up to 1500 mW/cm2; Low mode: up to 650 mW/cm2; SoftStart: up to 1500 mW/cm2; Pulse: up to 1500 mW/cm2. It is processor controlled for constant light power regardless of the charge level. The long-lasting lithium-ion battery has no memory effect, can be fully charged in 180 minutes, and will last for 500 10-second cycles on high mode, or 1,000 10-second cycles on low mode. The Light 405 includes a dual wavelength processor designed to meet all standard operatory light curing needs, including that of our new product, OPTIGLAZE Color. Contains: 1 handpiece (approx 130 g), 1 charger (approx 100 g), 1 user manual, and 1 box of 100 disposable covers
