Optimized for 12 o’clock mounting on rifles with top rails, ROSCH Works SL1’s 250+ lumen lighthead was designed “in collaboration with LED lighting industry legend Gene Malkoff,” Wait. The LED lighting industry has a legendary designer? Yes, wherever LED industry folks gather—whether it’s a dingy hotel bar near a poorly lit conference center or a small cubicle with lumen-appropriate task lighting—the name Malkoff is uttered with quasi-religious reverence. At some point someone intones the sacred words: ”I Love God, My Family, and My Country. It is my Belief that Traditional Family Values and Honest Work are the Pathway to Happiness.” Where was I? “The combined light & sight saves rail space and weighs only 3.2 ounces with a CR123 battery and is less than 3.5” long, making it the lightest and smallest solution for providing both a light and front sight! The twisty style tailcap provides quick, momentary activation that is ideal for quick bursts of light on the target in between moving between shooting positions.” Nick’s all over it.
