The VBRG is both a UV Curing Lamp and the tool that attaches the Vanish™ Injector Assembly to the windshield. The sub-15 Second DarkCure™ Extreme UV LED Curing System is a radical breakthrough in the windshield repair industry. Ultra-High Intensity, Short Duration UV LED curing penetrates deeply into any repair from all sides, cutting cure times by 90% and improving cure strength even after the system is turned off! The DarkCure™ integrated Lithium Ion Battery will last approximately 150-200 repairs before needing to be recharged. 1 hr charging is as easy as plugging the DarkCure™ system into an outlet with the included charger.
