A penlight, often known as a pocket mild, is a small, transportable flashlight. Penlights are sometimes powered by one or two AA or AAA batteries and have a single LED or incandescent bulb.
Penlights are sometimes used for close-up illumination, corresponding to studying, writing, or engaged on small objects. They’re additionally standard for tenting, mountain climbing, and different out of doors actions. Penlights are comparatively cheap and could be simply carried in a pocket or purse.
