Penlights and inspection lights shine a small, focused light beam onto specific areas or into tight spaces where flashlights would be too large or overpowering. Also known as flashlight pens, these slim lights slip into a pocket to stay within reach as needed. General purpose penlights provide a light source for offices, medical exams, and light-duty applications that don't require industrial or safety-rated penlights. Industrial penlights and inspection lights withstand heavy use for inspection, facility maintenance, automotive and machinery repair, and other applications where they may be subject to dirt, grime, impacts, and drops. Safety-rated penlights illuminate areas where flammable, combustible, or ignitable materials are present.
