In short
Good for
- Life at camp: cooking, sorting kit and sitting round a stove or fire
- Summer and shoulder-season overnighters where the lamp is mostly used at camp
- Anyone who wants a wide, softer beam and warmer light modes in a head torch
Strengths
- 350 lumens (FL1) with a wide 30-degree beam and softer ambient and campfire lighting
- Built-in USB-C rechargeable battery (1200 mAh), 175 lumens for 7.5 hours
- 75 g, oversized two-button control, digital lock and battery meter
- Red light shortcut
- Recycled headband; 3-year Black Diamond warranty
Weaknesses
- No independent review yet, so comfort and beam are estimates, not reviewed scores
- The lamp doesn't tilt, which Ultralight Outdoor Gear's own write-up calls its main drawback, especially for close work
- Wide, soft beam with a 55 m reach: made for camp, not for picking out distant ground
- IPX4 only: splash-proof, not for heavy rain or immersion
- The battery is built in, so there is no AAA back-up and no swapping a spare
