Inside you'll find the brain of the flashlight – a custom CWF Quantum Chimera driver with low voltage protection, reverse polarity protection, and thermal protection of the emitter designed to be simple to use. This non-programmable driver powers the LED and allows switching between the three modes (Low, Medium, and High) by clicking the rubberized and textured tail switch. The 4000k Nichia 219C is a powerful and color-accurate LED that leans on the warmer side. A smooth conical reflector makes a brighter center beam with a bit of flood around it, perfect for nearly any task.
