Black Diamond Spot 400

R Runner's World Cat Bowen · reviewer · Sept 2018

This headlamp hit the sweet spot on long runs. Its balanced front and rear design meant zero bounce, even during faster intervals. The sweat-wicking strap kept things comfy in muggy conditions. The beam spread was both wide and focused, letting me scan the road ahead and side trails with ease.

First impressions, super solid, lightweight, and this color is just chef's kiss. Now, what makes this headlamp stand out? For me, it's the power tap technology. Seriously, it's so intuitive. Just a quick tap on the side and boom, you switch between full power and a dim setting.

The Black Diamond Spot 400 is my reliable backpacking headlamp pick because it delivers the durability, brightness, simplicity, and value I need after dark. I’ve carried a headlamp on every wilderness trip since 1986.

The main difference is that the Spot 400 has some weight savings and is 50 lumens brighter—without sacrificing battery life. The Spot 400 max beam is also 20 meters farther than the Spot 350.

With excellent features and performance, the Spot 400 is the clear winner for Best Battery-Operated headlamp.

For night hikes or climbs, 400 lumens provide a reasonably strong beam for navigation, though I would generally prefer a more powerful head torch.

The “boost” brightness goes beyond 400 lumens but burns through battery in under 30 minutes. Treat it as emergency-only.
