Serfas True S250 USB Front Light

Pushing out over 250 lumens in overdrive mode, the TSL-S250 commands your attention on the road or on the darkest mountain trail. The TSL-S250 features a unique user replaceable battery. With additional batteries avaliable for purchase, you can charge up an extra, slide it into your jersey pocket, and ride all night long! This lightweight, compact light includes a handlebar mount, USB Charger, and Wall Charger adapter. You’ll never have to worry about overcharging either, the built in smart charger protects your battery and eliminates any chance of this happening.

Serfas has changed the game on high powered lighting by testing its lights in house with a 20” N.I.S.T traceable standard intergrating sphere. As the name infers, The Serfas “True” lights promise that you will always get what you pay for.
