This is a dim light with a low beam quality score that was among the lowest performers of the 16 lights tested.
Knog Skink Review
Cons: Concentrated beam, low light output, no battery life indicator, silicone cover can gets dirty easily, AAA batteries are expensive over the long-term.
Our Analysis and Test Results
The light has a concentrated beam that is very poor at close proximity and peripheral lighting. This makes it harder to see the road and harder for cars to see you, compared to lights with wider beam patterns. Due to this significant drawback, the light doesn't score well in this metric. Compare that to the Metro 360 below.
We measured maximum distance at 24 meters. This is significantly below the Metro 360, which shined 135 meters. As you can see in the photo below, the light is barely effective at lighting up roads and paths. Our testers used it on blinky mode only, but even then, due to the narrow beam pattern, we found that the light was relatively poor at catching the attention of automobile drivers.
It's small and lightweight. The light's simple stretch and hook mount is very easy to use, but is not as secure as lights with adjustable mounts.
We measured the battery life at 8.3 hours. This is not bad, but since you can't charge this with a USB cable, the cost and pain of replacing batteries will add up if you ride a lot at night.
This was one of the lowest performing lights in its price range. The Knog Blinder 4 Standard is only a little more expensive and a much higher performing light if you are looking for something compact. The only lights that performed lower cost $12-25.
