The Nebo Mycro is a tiny rechargeable headlamp that converts into a cap light. The small light unit fits into an adjustable head strap for hands-free use, or clips onto the brim of a cap with the included clip, which makes it popular for walking, running, fishing, camping and close-up work under a car bonnet or a sink. It tilts so you can aim the beam where you need it and charges by USB, so there are no disposable batteries to buy. This is the original Mycro headlamp and cap light; Nebo has since replaced it with the Mycro 250, 450 and 550 models, and we could not find the original specification sheet, so check the packaging for the exact light output, modes and runtime.
