The Nebo Davinci 800 is a compact rechargeable zoom flashlight giving up to 800 lumens and a beam of about 128 metres. It has four modes, high, medium (400 lumens, 5 hours), low (100 lumens, 20 hours) and strobe, selected with a tail push button, and starts on low. A 3x zoom takes the beam from a wide flood to a sharp spot. The aircraft-grade aluminium housing is IP67 dustproof and waterproof to 1 metre for 30 minutes. Its 18650 2200mAh lithium-ion battery charges by USB-C in about 3 hours, and a USB-A port lets you use the light as a power bank to top up a phone. In the box: flashlight, battery, USB-A to USB-C cable and lanyard. Nebo gives a 1-year warranty.
