This LED Light Just Plain Works Well

By Jim

About Me Avid Cyclist

Pros

  • Great visibility
  • Long battery life
  • Low battery indicator
  • Rechargable

Cons

  • Weak beam

Best Uses

  • Front headlight
  • Night commute

Comments about Serfas Thunderbolt Head Light:

--I use this light on the handlebar of my Cannondale Badboy 1, which I use as a police patrol bike.
--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...

Very bright, low battery life

By Ex. Jim the Runner

Verified Reviewer

Pros

  • Great visibility

Cons

  • Short battery life

Best Uses

  • Front headlight
  • Night commute
  • Rear safety light

Comments about Serfas Thunderbolt Head Light:

I've never seen bike lights with better car visibility, and the front one can be slightly helpful as a headlight for potholes on dark streets. It's true, you may need to charge them about once a week. It's extremely frustrating when they run out of batteries. I don't really understand the low battery indicator. Overall I'm quite happy with mine, as long as I keep them charged. They make me feel safer in traffic at night.

Use this light for commuting from work to home at night. About a 45-minute ride. Cannot get through a work week on one charge. I use the blink mode, and I have to cycle though several other mode everytime I turn it on.
