Knog Blinder MOB Mr Chips front light



Small light that packs a punch without killing the battery

At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

The Knog Blinder MOB Mr Chips is a very good small and powerful front light that makes you very visible on the road, and makes the road visible in the dark. It has a useful five modes and pumps out 80 lumens, which makes sure it lives up to the Blinder part of its name. The only thing I would consider changing is the USB charging, but that is just a small aspect of the overall quality.

I've been testing and using several lights of late, from the handlebar-bendingly huge to the invisibly small. This Knog Blinder sits towards the smaller end, but unlike many others in this category, it really packs a punch.

Pumping out 80 lumens of light means that you have to be careful to position it facing slightly downwards, as taking a full blast of this in a rear view mirror wouldn't be a pleasant experience. It means you are very visible to everybody around you, and you can see signposts reflecting the light back at you from considerable distances.

The light comes with five modes: the full 80 lumens on a steady beam ('steady high'), a slightly lower output beam ('steady low'), 'strobe' flash, pulsing flash ('fancy flash'), and 'eco flash' – flashing on left/right sequences. These will fit the needs of most, and with the 80-lumens full beam I could navigate in the dark on the road (it probably wouldn't be good enough for night trail riding).

Battery life is very good, although this is dependent on how you use it. It can run for around four hours on the full strength beam, but using it on the eco flash (the mode I most commonly used) it lasts around 60 hours (I didn't ever run out of power in this mode despite long uses). And when the battery is running low, a red light indicates that the unit needs to be charged.

Knog achieves this impressive battery life by using low-power LEDs, which can pump out a bright light without rinsing the battery, meaning small size and bright light.

Charging is done through a USB attached to the light itself, so the light attaches direct to the computer/plug, cutting out the need for additional cables. It is useful, but does cause the only slight concern I have: that after a long wet ride, you don't really want to plug a wet light into an electric socket. That said, you can just wait for it to dry or dry it yourself, then it's safe. Knog does say that it's "designed to be exposed to the elements, is waterproof and will not be damaged by exposure".

Fitting the light to the bar is simple, and it has the added bonus of being able to attach to aero bars because of the shape of the back. This is done through a secure strap with a sturdy metal buckle. Throughout the testing period the light felt sturdy even on cobbles and rough surfaces.

The Blinder comes in at £35, which is reasonable for a light of this quality. I used it in torrential rain with no adverse effects and it pumped light into the road ahead of me, so for safety and reliability it's a price worth paying.  

Overall, I am very impressed with this little light. It manages to pack a real punch despite its small size, and the battery life is impressive: you can just leave it on your bar for days and not worry about it (somewhere safe, of course). It is also nice to see that Knog has considered performance riders who want to ride their aero bikes during the winter, something that's often ignored by light manufacturers.
