ABOUT THIS CATEGORY
Penlights and inspection lights are small devices that project a strong beam of light. They generally resemble the shape and size of a pen with a light-emitting diode (LED) light source powered by batteries. Penlights are highly portable and are commonly used in the medical field by doctors in examining patients. They are also used in industrial, commercial, and household applications in inspecting dimly lit areas, crevices, or components.
