Review summary
Petzl Actik Core is a run light / headlamp (625 lumens class). 625-lumen hybrid rechargeable (CORE or 3×AAA) all-rounder — enough mixed beam for dark roads and moderate trails when you want Petzl ergonomics without Swift/NAO reactive pricing. I'd shortlist it for hybrid CORE/AAA means you can finish a long night if the rechargeable dies.
The trade-off is no REACTIVE LIGHTING — you manage output yourself vs Swift/NAO RL — Black Diamond Spot 400-R is the cleaner compare when that is most of your week. It fits buyers who actually need a run light / headlamp (625 lumens class), not a one-product rotation.
