The Knog Blinder 4V has four super bright LEDs that pump out 44 lumens of light. It’s optimized optics focus and directs a smooth beam pattern that makes the Blinder visible over 800 meters. With five different modes (steady, fast flash, organic flash 1, organic flash 2, and eco flash) and a burn time of up to 5 hours in constant beam and up to 50 hours in eco- flash mode, they will ensure that you are well seen.

Comments about Knog Blinder 4 V Usb-Rechargeable Light:
I've had several knog rear lights and this is best one yet. It has many different light modes that provide maximum visibility vs maximum battery savings. The strap closure seems to work well and will hopefully hold up over time.
