The Spot 400-R is the value pick — IP67 waterproofing and a sealed-battery design at a lower price point than the premium picks. PowerTap (tap the side to flip between high and dimmed) is the small UX touch that makes it nicer to use day-to-day. The aging micro-USB port is the obvious downside in 2026, and the sealed battery means you can't swap it on a long trip. For casual campers and everyday users, the Black Diamond reputation alone makes this the safe pick at $60.
Strengths
- +IP67 waterproof rating — full submersion to 1 meter for up to 30 minutes
