Dishan LED Medical Penlight for Nursing Students Doctors Use Torch Smart Pen

A penlight is a small, portable flashlight that resembles a ballpoint pen or a fountain pen in size and shape. Penlights are commonly used to shine light in tight, enclosed areas, for example, inside the cavity of the ear where a doctor may look for earwax blockage, to inspect equipment such as car engines or plumbing fixtures, and to read books or maps in low-light conditions. They are compact and portable, easily fitting in a pocket or purse, and are generally powered by small, single-use batteries.
