15-80 Wide Angle Focusing, Multi-purpose Technology Realization: Adopting high-precision optical lens group, it supports 15 narrow beam focusing to 80 wide-angle scattering infinitely adjustable, covering the needs of the whole scene such as reading, office, handwork, and so on. User Scenarios: Students/Office workers: Narrow beam focus on textbooks/documents, reduce screen reflection; Bedtime reading: Wide-angle soft light covers the whole page, avoiding localized strong light stimulation; Outdoor use: with charging treasure, wide-angle mode illuminates the reading area in the tent. Infinitely adjustable color temperature (2700K-6500K), matching the circadian rhythm Technical parameters: Warm light mode (2700K-3500K): suitable for nighttime reading, reduce blue light to inhibit melatonin secretion; Natural light mode (4000K-5000K): simulate daylight, suitable for long hours of office work; Cold light mode (5500K-6500K): to enhance concentration, suitable for drawing / fine work. Cold Light Mode (5500K-6500K) Three aperture modes, intelligently adapted to the environment Functional design: High light mode: 1000lm lumens, suitable for dark light environment (such as dormitory lights out); Soft mode: 500lm lumens, with wide-angle diffusion, to avoid paper reflection; Night light mode: 100lm light, do not disturb the sleep at night.
