Black Diamond or Petzl — which headlamp brand is better?
Both are premium headlamp brands with strong reputations. Black Diamond is known for rugged construction and battery flexibility. Petzl is known for beam quality and ergonomics. At the $50 price point, the specific models matter more than brand preference.
How many lumens do I need for hiking?
For trail hiking at night: 100-200 lumens is adequate for most terrain at moderate pace. 300-400 lumens is useful for technical terrain, camp setup, and signaling. Maximum output (400-450 lumens) drains batteries fast — most hikers use mid-range settings for 90% of use.
Can I use rechargeable batteries in the Black Diamond Spot 400?
Yes — the Spot 400 accepts standard AAA NiMH rechargeable batteries (Eneloop, Amazon Basics). Charge them with a standard AAA charger. Note that NiMH performance drops in cold temperatures; use lithium AAA (non-rechargeable) for winter camping.
