The Nebo Columbo 100 is an ultra-compact pen-style inspection light that fits in a shirt pocket and runs on a single AAA battery. It gives 100 lumens on high for about 1.5 hours with a beam of about 56 metres, 35 lumens on low for about 4.5 hours, and a strobe. A 4x zoom lets you switch between a wide flood for looking around and a tight spot for checking inside an engine bay, cupboard or electrical box. The anodised aircraft-grade aluminium body is IP67 waterproof and impact resistant to 1 metre, and a single rear button handles power and modes. It suits mechanics, electricians, inspectors and anyone who wants a small backup light in the car.
