If you want a light curing system that can "do it all" look no further than the remarkable G-Light from GC. Not only does the GC G-Light employ the very latest LED technology, it has unique blue AND violet LEDs that give two different wavelength peaks capable of curing all visible light curable (VLC) materials. You also get the high performance, reliability and simplicity that comes with high quality Japanese electronic design and manufacture. Advantages One light-curing system, whatever the photo-initiator Unique combination of one violet LED and seven blue LEDs which operate at different wavelengths (violet: 400-420 nm, blue: 465-475 nm) These activate not only camphorquinone but also other photo-initiators, making GC G-Light one of the few truly versatile curing systems available High performance and reliability Faster, deeper cure, due to unique design of LED module and high intensity of 1200 mW/cm2 More than 400 irradiations of 10 seconds with one battery charge Lithium-ion rechargeable battery meaning no "memory effect" Long lasting LED module, designed to offer a stable and continuous output for several years Very simple to use Variable curing time: 5, 10, 20 seconds, and a continuous mode. The lamp indicates a particular mode is selected Stop / Start button and timer selection can be activated with one hand Ergonomic: simple design to ensure grip and well- balanced weight to ensure maximum comfort while working
