Similar to the MasterLazer LED™ Universal Light Source System (871-0919) but is designed for no-tools external installation using tubing-activated parts. This model does NOT support LED curing, but it is an economical way to light ANY brand of fiber-optic handpieces—even different brands at the same time. Complete system consists of small power pack that can operate 2 separate handpiece lines and a wall transformer. Mounts externally using Masterlight™ external tubing.
