Unlike a standard flashlight which is designed to flood an area with light and may not provide the correct lighting to see all defects, the LL150 utilizes a very specific light spectrum, lumen, and adjustable beam pattern that are ideal for seeing the fine lines and imperfections on automotive paint surfaces. With a push-button, tail-cap switch for single-handed operation and a sturdy clip to secure the light to a pocket or belt when not in use the RUPES Swirl Finder Pen Light has all the essentials needed to be a great addition to any professional shop or serious enthusiasts garage.
