Product Name: Loupe System - A MACRO LENS FOR THE EYE Product Details: The Loupe System v3 Light Ring accessory can be installed on all Loupes (6x model 01, 3x model 02, or 10x model 03) simply by replacing the current center ring and lower rubber element of the Loupe. The V3 Light Ring, covered in 3K woven matte carbon fiber, provides the Loupe with three different user-selectable lighting settings. Light Mode 1: 4,000K neutral white light only (adjustable from 5% to 100% intensity). Light Mode 2: 4,000K neutral white light (adjustable from 5% to 100% intensity) and 365-370um UV light (always at 100% intensity). Light Mode 3: 365-370um UV light only (adjustable from 5% to 100% intensity). The UV light intensity of the v2 and v3 light rings has increased to 220% compared to the V1 light ring, due to the doubling of the number of UV LEDs present in the ring and a slight increase in drive current. The V3 Light Ring includes two custom-molded single-cell lithium polymer (LiPo) rechargeable batteries, each connected to its own dedicated charge/discharge circuit. These batteries are charged using either of the two included USB cables. This cable must be connected to a USB wall charger, computer port, or power bank. The V3 Light Ring accessory is packaged in a waterproof and airtight transport case designed to protect it during storage and transportation. The transport case is designed to have the inner foam elements removed so that it can be used as safe, waterproof storage for electronics and other delicate items when going to the boat or beach.
