How we calculate scores →About this gear
The NR-4000 separates its battery canister from the light head and includes a Goodman handle. Kraken lists 4000 lumens, an 8° beam and three hours at full power. Straight and Sidemount versions offer different configurations, so the exact arrangement matters more than a generic canister-light label.
Consider before buying
The complete system weighs 1740 g on land, substantially more than a handheld torch. Check canister mounting and cable routing with your actual harness before ordering. The manufacturer’s endurance figure is not an independent burn test, and handheld NR-series battery or charging details should not be carried over to this model.
Our take
Consider NR-4000 when its separate battery and longer listed endurance solve a real need. NR-2500 is simpler to carry when a self-contained handheld meets the plan. We found no eligible independent overall rating for the canister model; its use in demanding environments requires an appropriate lighting and redundancy plan.
