The Beyond Power Whitening System features the Beyond Whitening Accelerator. The Beyond Whitening Accelerator uses the most advanced technology to produce a cold-light with a wavelength of 480-520 nanometers. The light is filtered through over 12,000 fibers, reaching a total length of one mile, and finally through an optical lens coated with more than 30 protective layers. The process removes harmful heat and ultraviolet light, making the Beyond Whitening Accelerator the most advanced cold-light whitening device on the market.
