The Daylight Halo Go Rechargeable is designed with portability in mind. It features a USB rechargeable battery that provides a full 8 hours of consistent brightness. The LEDs circle the Halo Go’s magnification lens; giving a uniform lighting experience. The magnifier offers 5 dioptres (2.25X) magnification with a 12 dioptre (4.0X) inset lens for fine detailed work. The Halo Go folds flat for easy transport and storage.
