The Serfas Thunderbolt (USL-6) gives you high performance and endless mounting options, and is a stellar bargain buy. The 15- micro (double strength) LED strip puts out 90 lumens, giving you plenty of light as you safely ride to your destination. The light can be seen up to 1 mile away, giving cars ample time to move out of your path. With 3 light settings, you’ll always be ready for what’s ahead. You won’t find yourself riding to your local 24 hour pharmacy for batteries any more, as the USL-6 Thunderbolt is USB rechargeable!
- Can be seen up to 1 mile away
- Light installs/ removes from bar in 3 seconds
- USB rechargeable
- Modes: Lo/Hi/Flash
- 9 hour burn time
--This light is incredibly bright. So much so that I ride it on its lower flash setting mostly. While on patrol, I find it quick and easy to turn on and off, it's weather resistant, and very rugged. It looks awesome on a black bar, and it truly is an incredible beacon for cars to see me at night. I haven't had any issued with charging time or battery life.
--It is not bright enough to be used as a headlight for illuminating your path. 90 lumens may sound like enough, but it's so dispersed that it's almost worthless for that. It's a "Here I am, don't run me over." light.
I will buy another for my motorcycle.
Cheers from Florida...
