Petzl DUO RL
Petzl's DUO RL is a flagship helmet-front combo that pairs a long-range spot with a wide flood beam, engineered for professionals who need both distance and area illumination on a helmet. It commands a premium price but justifies it with superior beam throw, rugged build quality, and rechargeability compared with more value-oriented options like the Princeton Tec Apex and compact contenders like the Fenix HP30R V2.0, making it a top choice when maximum performance and durability matter and the light is required to be available for purchase now.
