The Ledlenser P4R is a rechargeable aluminium pen light for people who check documents, meters, wiring or other fine detail. It clips into a shirt pocket and uses Ledlenser's Advanced Focus System to move from a wide flood for close-up work to a focused spot for more range. Three brightness levels give up to 300 lumens and a beam distance of up to 100 m, controlled by an end cap switch. Dual Power Source means it runs on its 700 mAh lithium-ion battery, which charges directly via a USB-C port on the battery, or on standard AAA alkaline or NiMH cells as a backup. Runtime is up to 1.5 hours on power and 13 hours on low. It is 142 mm long, weighs about 57 g, is rated IP54 and drop tested to 2 m. The aluminium parts use 75 % recycled material. A charging cable is not included. Ledlenser offers a 7-year warranty when the product is registered.
