Clinical Flashlight

A Pen Torch (penlight) is a compact, handheld, battery-powered diagnostic illumination device essential for directed clinical examination including pupillary reflex assessment, oropharyngeal and nasal inspection, wound visualization, foreign body detection, and transillumination. Available in reusable clinical-grade (aluminum/stainless steel, replaceable batteries, LED/incandescent) and disposable (economical plastic, single-patient-use) configurations. LED models provide 20-200 lumens with beam angles 5-60°, color temperature 4000-6500K, and CRI up to 90+ for accurate tissue assessment. Features include pocket clip, end-cap or slide switch, and lightweight construction (20-80 grams). Primary clinical applications include neurological examination (pupillary reflexes, cranial nerve assessment), emergency trauma evaluation, primary care physical examination, critical care monitoring, and pediatric assessment. Class I medical device. Critical safety considerations include ocular safety (avoid prolonged direct exposure), infection control (disinfect reusable devices between patients), battery safety, and contraindication in sterile fields unless sterile-wrapped.
