That is the difference between a working light and a dead one on a winter ridge.READY AT 10,000MFearless in thin, low-pressure air. The HLB2500 delivers stable power at altitudes up to 10,000m, so it keeps working through the summit push where the air, and lesser batteries, run out.SEALED TO IPX8At home in snow, rain and immersion.
