This little light packs a most powerful punch! I took this little headlamp with me to summit Mount Elbert in Colorado, which is the second highest peak in the US! The nature of this mountain is that it creates its own weather, so starting early is a must and you often start your summit in the dark. The HM50R was light enough to make the journey easy before the sun came up, and was easily packable. The spread of light is great for reading and hiking in the dark.
