Which one to pick
Take the Black Diamond Spot 400

Take the Petzl Actik Core

- You want a red mode that comes on without cycling through white first
What each one gets wrong
Black Diamond Spot 400
- You want rechargeable out of the box — the BD pack is a separate purchase
- You need output that holds steady, since alkalines fade as they drain
- Thick gloves are the norm; the single button asks for taps and holds
Petzl Actik Core
- The lamp will be out in sustained rain; IPX4 is splash, not weather-proof
- You need a beam that reaches, rather than one that floods close ground
- You object to a proprietary pack you will eventually have to replace
