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. Lux is a similar method to measure light across a surface area that is often used in European markets.

Bought this to replace my cateye tail light after 10 years of service. I went for a set as the red cobbler was sold out. I really wanted to like these lights, it's a shame that I'm here writing this review.

Lights themselves are nice, but they are not made to last. The integrated USB connector looks very fragile, if you break it the light is done and you throw away everything (with battery and so on). Why not using a cable? If you break a cable, you pick up an other that you probably have around and keep using the light. In addition to that, the connector is exposed to the elements and I can't imagine using the tail light in wet conditions, getting sprays and grit from the back tyre (not to talk about sliding the partial cover on it with all the grit on the way, or plugging in this dirty thing in your laptop).
The integrated connector makes it also very inconvenient when charging (do you really want to have that big thing sticking out of your laptop or power bank with the risk of breaking it?). In principle, you can use an extension cable, but you will have to bring its own cable around (you can't use the one you have for your phone) so this defeats the purpose of "cable free" charging.

I went for Kong as I like a lot my Scout, but I will not be buying bike lights from Knog anymore.

These babies are bright

They look super cool, shine very bright, innovative charging port, all around great investment. I am hoping they last!

Big Lights, much likes

Super easy to pop on and pop off, I have to make sure to angle the front light extra down so it doesn’t blind me. Most excellent lights.

Incredibly bright, love the patterns.

These lights are unlike anything I've used before. They are incredibly bright and the angular range and patterns make me feel better about being seen in the coming darker months.

Took off a star because I don't trust the mounting. O-Rings have failed on me before, and it feels like it wouldn't take much for the light to bounce out of the mount. Time will tell I suppose.

The charging solution is interesting but I worry about how waterproof it might be.

light great - fitment not so much

Love the brightness and the choice of light patterns / strobes but the front light is very hard to find a good fit to my bike as it is too narrow for the handle bar stem - which there were parts to adapt to different diameter tubing

'this is simply the best bike light set for attracting the attention of other road users.'

‘Knog’s Cobber is an impressive light with a simple and elegant design.’

Why you'll love riding with Big Cobber.

The world's only 330 degree bike light.

Simple Button

Big Cobber bike lights are simple to operate. A long press of the single button will turn the lights on / off, and a short press will cycle through their modes.

Packed With Innovation

Efficient Chip on Board (COB) LEDs provide maximum brightness level for up to 90% of the battery burn time. As well as 8 pre-programmed modes, both are compatible with Knog's ModeMaker app so you can customize light modes.

Mount With Ease

Cobber comes with removable silicone straps for handlebars / seat posts 22 – 32mm+ and head tubes up to 200 mm in diameter. Aero & standard mounts included.

Integrated USB Connector

Big Cobber plugs directly into USB-A ports. When your Cobber is running low on battery, a red ring will light up around the button. This ring will turn green, then off once fully charged.
