USB Rechargeable at a great price!!!
I've tried 3 other lights prior to getting my hands on this one. The other lights had issues such as poor light quality (brightness), poor build quality (light would shut off from road bumps), etc. This light does not. It's sturdy, and the light is VERY bright. 350 lumens is more than adequate for my 4:30am rides. These self-contained units are great...no cables or battery packs to deal with. USB charging is great as well - super convenient. Very happy w/ the light.

These lights are INCREDIBLY bright. They have no issues staying put, even on bumpy terrain.
Admittedly this is the first light I've ever purchased for a bicycle (I also purchased the Thunderbolt Taillight which is equally as good), but I'm so happy that I'm fairly certain Serfas has a life long customer in me.

I genuinely can't find fault with this light. It has good battery life and is superb for lighting up the path in front.
I have been using it helmet mounted in conjunction with a thunderbolt, other lights too, I can't be missed. I've been able to identify hazards in the road before hitting them, potholes etc. Also, I can shine the light on corners like a car's headlights, so you can warn a car of your presence well before it's right on top of you. This really improves your own personal safety on the road. The brightness of the light will also make your presence abundantly clear on the road too obviously!
A definite must have and well worth the money. I wish serfas had a bigger presence here in the UK!
