Compact, powerful, and USB-rechargeable. Serfas’ true series pack a punch in the commuter and trail light category, and have impressed editors over at MTBR.com.
The TSL-550 was praised by MTBR’s founder, Francis Cebedo, for its durability, robust cooling fans, and interchangeable optics. Factor in the included bar and helmet mounts and USB wall charger in the box, plus its excellent lumen-to-dollar ratio, the TSL light series offer great performance and excellent value.
