Black Diamond headlamps cover every need, from a simple, lightweight model to an ultra-high-performance headlamp built for night trail running. At 4c+, we've selected four models that cover the essentials of our activities: climbing, mountaineering, trail running and bivouacking. Here's our selection, featuring the official Black Diamond technical specifications and, more importantly, what each model is really designed for.
How to choose your headlamp: the numbers that matter
Before comparing models, four specifications make all the difference:
- Lumens measure maximum light output. The higher the number, the brighter the beam — but also the higher the battery consumption. There's no need for 1,000 lumens just to read inside your tent.
- Beam distance (m) tells you how far the light reaches. Keep in mind that, with the same lumen output, a focused spot beam reaches much farther than a wide flood beam, which is designed for running. That's why two 500-lumen headlamps can illuminate either 120 m or only 50 m depending on their intended use.
- Runtime (h) is the maximum operating time, generally measured in the lowest power mode. It's a critical factor for bivouacs and long mountain days.
- Water resistance (IP rating): IPX4 withstands rain and splashes, while IP67 is dustproof and can survive temporary immersion — an essential feature for mountaineering and heavy rain.
Add the weight (for comfort on your head and in your backpack) and the charging system (USB-C, micro-USB or backup AAA batteries), and you'll have everything you need to choose the right headlamp.

Our Black Diamond selection in detail
Astro 300-R — the headlamp everyone should own
Who is it for? Rock climbing, camping, hiking or simply keeping in the bottom of your pack for emergencies. The simple, affordable headlamp.
Compact (100 g) and rechargeable, the Astro 300-R delivers 300 lumens, a 55 m beam distance and up to 140 hours of runtime. It features a recycled elastic headband, brightness adjustment and strobe mode: everything you need, without unnecessary extras, at the most affordable price in the range.
Specifications: 300 lm · 55 m beam distance · up to 140 h runtime · 100 g · IPX4 · rechargeable 1500 mAh Li-ion battery (micro-USB).

Storm 500-R — reliable in every weather
Who is it for? Climbing, mountaineering, rain and demanding mountain conditions. The versatile headlamp you can rely on.
With its IP67 waterproof rating and an impressive 350-hour maximum runtime, the Storm 500-R is built for the mountains. Although it shares the same brightness as the Sprinter, its focused beam reaches much farther (120 m). It also features PowerTap technology for instant full power, multiple lighting modes and RGB lighting (red, green and blue) to preserve night vision.
Worth noting: at 150 g, it's the heaviest model in the range, reflecting its rugged construction and larger battery.
Specifications: 500 lm · 120 m beam distance · up to 350 h runtime · 150 g · IP67 · rechargeable 2400 mAh Li-ion battery · PowerTap · RGB lighting.

Sprinter 500 — built for movement
Who is it for? Trail running, road running and fast approaches. The headlamp that stays stable while you run.
The Sprinter 500 prioritises a wide flood beam that illuminates the ground immediately ahead, making it perfect for running. It features a breathable perforated headband with an overhead strap, plus a flashing red rear light for increased visibility on roads. Its deliberately shorter beam distance (50 m) is the trade-off for broad, comfortable illumination while moving. A practical bonus: it can also run on AAA batteries in an emergency.
Specifications: 500 lm · 50 m beam distance · up to 100 h runtime · 130 g · IPX4 · rechargeable BD1800 battery or AAA batteries · flashing rear red light.

Distance LT 1100 — maximum power
Who is it for? Mountaineering, night trail running, long alpine missions and rescue operations — any situation where seeing farther is essential.
The most powerful model in our selection, delivering 1100 lumens with a 110 m beam distance (up to 125 m using PowerTap), all packed into a remarkably lightweight body weighing just 108 g. Fast USB-C charging, IP67 protection, an adjustable beam and a washable headband make it a true endurance headlamp for serious objectives.
Specifications: 1100 lm · 110 m beam distance (125 m with PowerTap) · up to 120 h runtime · 108 g · IP67 · Distance LT 2200 mAh rechargeable battery (USB-C) · adjustable beam.

- Trail & running → Sprinter 500
- Maximum power and beam distance → Distance LT 1100
Tips for choosing the right headlamp
Don't chase lumens alone. A powerful headlamp used continuously at maximum output can drain its battery within a few hours. For bivouacking or reading, a low mode between 6 and 300 lumens is more than sufficient and can last for dozens of hours.
For mountaineering and wet weather, prioritise an IP67 waterproof rating over raw brightness. If you're running, beam width and stability matter much more than maximum beam distance. Finally, recharge your headlamp before every outing and protect it from extreme cold, as low temperatures reduce the runtime of lithium-ion batteries.
Frequently asked questions
How many lumens do you really need?
For hiking and camping, 200 to 300 lumens are more than enough. For climbing and mountaineering, 500 lumens provide an excellent safety margin. Above 1000 lumens is primarily intended for fast night trail running or terrain where long-distance visibility is essential.
What do IPX4 and IP67 mean?
IPX4 protects against rain and splashes. IP67 goes much further: it's dustproof and withstands temporary immersion up to 1 metre for 30 minutes. For mountaineering and wet environments, IP67 (Storm 500-R and Distance LT 1100) offers a real advantage.
Why don't two 500-lumen headlamps illuminate the same distance?
Because beam shape changes everything. The Storm 500-R uses a focused spot beam that reaches 120 m, while the Sprinter 500 uses a wide flood beam that reaches only 50 m but provides much more comfortable illumination while running.
What is the red light mode for?
Red light preserves your night vision and prevents dazzling your climbing partners or tent companions. It's especially useful in mountain huts, during bivouacs or when reading a map without ruining your night-adapted vision.
