Lumens are a measure of the total amount of visible light from a light source. The higher the lumen rating the “brighter” the light will appear.
Using new Chip On Board (COB) technology, the Blinder rear bike light produces a punchy 100 lumens and is brilliant for attracting attention on the road or trail in all light conditions.

The Blinder Rear Bike Light
I am always looking for a decent rear light and after many months perusing your products I chose this rear light.
I couldn’t hide my disappointment when I first installed it and it has left me wondering about the amount of real world testing you do.
I shouldn’t have to point out that almost without exception the seat post, to which these lights are attached, is on an angle (commonly 73°) and when the Blinder Rear light is in place it points toward the ground and NOT in a horizontal direction.
You may consider this a moot point as there are many LEDS in this light, but compensating this directional mis-alignment by increasing the brightness is not a worthy solution.
How hard would it be to design the housing so that it accommodated this 73° slant of the seat tube and post?
And while you’re redesigning the housing how about moving the switch to what will now always be the bottom. This is a much better location, ergonomically, than scratching around on one side or the other.
My Moon rear lights have had issue this covered for many years.
Love it
Such a fantastic light. I'm sure that this light is the best bike light but forbidden to use in Germany. But who care's. I love the peace symbol.
Blinder Rear Bike Light
I need a slow blink at a lower intensity for our club rides. The Blinder doesn’t have it. I liked the idea of the mount closure but during the ride, mounted on the seat post, it kept touching the inside of my leg. The charge didn’t last on an under 3 hour ride.
