The LED Lenser P4 is great for engineers, technicians or anyone else who wishes to keep their flashlight clipped to a shirt or work wear. It also weighs so little that you'll hardly notice it. It features an easy to use tail cap switch. The P4 is powered by two standard AAA batteries (included). The P4 includes a holster/sheath, lanyard, split ring and pocket clip.
LED Lenser was founded in 1994 by twin brothers Rainer and Harald Opolka in their garage in Germany. Now LED Lenser has over 1000 employees, hundreds of patents and numerous design awards. There are a number of reasons to buy an LED Lenser flashlight, but one very good reason is that they stand behind their product with a five-year-warranty, wherein they will repair or replace the product and ship it back to you at their expense.
