Black Diamond Spot 400-R vs Fenix HM55R Renegade

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Fenix HM55R Renegade comes out ahead by a narrow margin (4.4 vs 4.7). The gap is mostly about users who want the brightest, most weatherproof rechargeable headlamp regardless of weight or battery format — read the strengths below before deciding.

Black Diamond Spot 400-R
Ranked #3 in Best Rechargeable Headlamps
Black Diamond Spot 400-R
$50as of May 19

The Spot 400-R is the value pick — IP67 waterproofing and a sealed-battery design at a lower price point than the premium picks. PowerTap (tap the side to flip between high and dimmed) is the small UX touch that makes it nicer to use day-to-day. The aging micro-USB port is the obvious downside in 2026, and the sealed battery means you can't swap it on a long trip. For casual campers and everyday users, the Black Diamond reputation alone makes this the safe pick at $60.

Strengths
  • IP67 waterproof rating — full submersion to 1 meter for up to 30 minutes
  • Integrated 1500 mAh battery with USB charging — no separate cells to manage
  • PowerTap dimming technology — tap the side to flip between max and dimmed instantly
Watch-outs
  • Older micro-USB charging port — slower than USB-C and uses an aging cable
  • Sealed battery — when it dies after years, the headlamp is done
  • Less bright than the Petzl Actik Core (400 lm vs 625 lm)

The HM55R Renegade is the brightest headlamp in this round-up — 1200 lumens combined output, an IP68 rating, and a serious 141-hour low runtime. GearJunkie named it the best headlamp of 2026, edging out the BioLite Range 500. The trade-offs are real but predictable: the brightest mode burns down the battery fast, and you're committed to Fenix's proprietary 18350 cell. For anyone who wants the headlamp equivalent of a high-output flashlight strapped to their head, this is it.

Strengths
  • 1200 lumens spotlight + 350 lumens floodlight in one unit — brightest pick in this round-up
  • IP68 waterproof and dustproof — fully submersible
  • Up to 141 hours of runtime on low — multi-day capable without recharging
Watch-outs
  • Bright modes drop battery fast — 1200 lumens is sub-hour runtime
  • Heavier than the Nitecore NU25 UL and Petzl Actik Core at 87 g (with battery)
  • Twist-on/off battery cap is fiddler than slide-out designs

How they stack up

Cheapest pick in this round-up — undercuts the Petzl Actik Core, BioLite HeadLamp 425, Fenix HM55R, and Nitecore NU25 UL on price. Highest waterproof rating tied with the Fenix HM55R (IP67 vs IP68). Loses to the BioLite HeadLamp 425 on comfort and the Petzl Actik Core on battery flexibility.

Fenix HM55R Renegade

Brightest pick here — 1200 lm vs the Petzl Actik Core's 625 lm and the Black Diamond Spot 400-R's 400 lm.

Loses to the Petzl Actik Core on battery flexibility and to the Nitecore NU25 UL on weight.
