Highlighted cells mark the better spec: Range 400 in blue, Dash 450 in amber. A blank spec is never counted as a win. Runtime is shown for context and is not scored, since makers publish it at different brightness levels. GearScore is the overall rating (0 to 100); re-weight it on the full headlamp comparison. Prices are current MSRP.
The BioLite Range 400 and BioLite Dash 450 take different routes to the same job. They are close enough that this really is about which handful of specs you weight most.
The Range 400 is 4 g lighter and $10 cheaper. The Dash 450 is brighter (450 vs 400 lm). Their GearScores land within a couple of points (74 vs 73), so neither runs away with it.
