Black Diamond Spot 400-R: The Rechargeable Headlamp That Doesn't Compromise
July 2, 2026
Quick Take
The Black Diamond Spot 400-R is the headlamp that most backpackers should buy. 400 lumens of max output, a rechargeable battery that also accepts AAA batteries as backup, waterproof construction, and a red night-vision mode make it the most practical headlamp in its price range. It's not the lightest or the brightest, but it's the most versatile.
What's New
The 400-R updates the previous Spot 350 with a higher maximum output (400 lumens), a USB-C charging port replacing the older micro-USB, and an improved battery indicator that shows remaining charge in four increments rather than a single low-battery warning. The PowerTap technology — a single tap on the top of the headlamp to switch between full and dimmed output — is retained from previous versions.
Key Features
- 400 lumen maximum output with dimming down to 10 lumens
- Rechargeable via USB-C; also accepts AAA batteries as backup
- PowerTap technology: single tap switches between full and dimmed output
