Bottom line: The Spot 400-R is the better value and covers what most hikers need. The Storm adds IP67 sealing, 100 more lumens, and a more robust housing for $20. If you hike in sustained rain or cross streams regularly, the Storm's sealing is worth it; otherwise the Spot is the smarter buy.

What does IP67 mean versus IPX8?
The first digit is dust protection — IP67 is fully dust-tight, IPX8 has no dust rating. The second is water: 7 means 30 minutes at 1m, 8 means continuous submersion. For hiking, the dust rating is often more relevant.
How many lumens do I actually need?
100-200 lumens handles most trail walking. 300-500 is useful for technical terrain and camp setup. Maximum output drains batteries fast and most hikers run mid-range settings.
Are these rechargeable only?
Both accept the rechargeable core and AAA batteries as backup, which is Black Diamond's best design decision — you are never stranded with a dead lamp.
