I picked this up to use for daytime riding. I also have the Lezyne Strip Drive for the rear. The Zecto is easy to mount with no tissues fitting over bar tape. On it's daytime flash setting, it's plenty bright. I've noticed drivers stopping sooner when pulling out from driveways, etc. I haven't had a chance to push the light beyond a 5 hour ride, but the battery has easily lasted that long.
These lights are excellent. Only used them 3 times but we can tell we are more easily seen by motorists. Application and recharge are easy. Shopped around a lot and glad we spent the extra on an excellent piece of equipment. Thank you.
I upgraded my bontrager flare light to this. Hands down a much clearer and brighter front light, Easy install and compact, I especially like the rechargeable capability. Just have to make sure you don't forget to recharge.
