With technology rapidly improving, more and more new bike-specific products are flooding the market. The days where local riders would smash the home trails at night using only their camping headlamps are long gone as new BRIGHT and CONVENIENT lights become available and more affordable.
Bike lights come in arrays of brands, LED types, power, mount types, sizes; you name it. Oftentimes you will step into a shop and notice the wall is covered with similar-looking products of different brands and different prices – How to choose the one that you need?
Now each rider is different and, as in everything about biking (is 26’ dead? Are you riding flats or clipless? Tall socks?), there are individual preferences for lights.
From retail and riding experience gained over the years, one can use this simple logic as a starter and come to very good conclusions about the type of light one would need.
TO SEE VS BEING SEEN
The first thing to sort out is the type of light needed, which can be answered with a simple question: As a rider, do I only need to be seen by incoming cars or other road users, or do I need to actually see where I am going? The former will require a less powerful light than the latter.
The human eye has evolved to quickly spot a moving target, and the speed at which an object is seen increases if the object is bright, hence the use of a flashing light when the sun goes down.
Thus, road users will quickly spot a flashing light from afar.
Additionally, lights used to be seen do not need to be the most powerful as their main purpose will be to attract another road user’s attention, not to see far ahead of the front wheel.
As such, if a rider only needs to be seen, then they can choose a light with less than 1000 lumens such as one from the Magicshine ALLTY series.
The ALLTY is a versatile light series that comes in a range from 400 to 2000 lumens.
The first of the series, the ALLTY 400, is bright enough so that when in use it will be seen early by road users, which will keep the rider safe even during daytime.
For more power and increased brightness, the ALLTY 600 and ALLTY 800 will be seen from even further away at maximum power, and will provide the rider with a larger range of brightness so the rider can tune the light according to the ride’s duration. For longer commutes, tune the light to a lower power and it will last longer.
Moreover, the ALLTY 1000, ALLTY 1500, and ALLTY 2000 are bright enough that if a rider gets caught in pitch black, the light will provide a powerful beam that shines far enough ahead of the front wheel so that the rider will be able to safely get back home without slowing down too much.
Now when a rider needs a light so that they can see, then a more powerful light is recommended.
The main reason is that the further up ahead of the front wheel you see, the faster you can ride. In other words, a light that isn’t powerful enough, such as below 1000 lumens, won’t light up the road far enough to allow you to see incoming obstacles (potholes, cracks, squirrels, …) when riding over 20 km/h. Obviously, one may be enjoying chill rides below 20 km/h, for which a 400 lumens light might very well provide sufficient power.
LIGHTS FOR DIFFERENT TYPES OF RIDES
The next question in the decision process is: For what type of rides will I need this light?
Evidently, someone riding brand new pavement is not subjected to the same challenges as someone that is mountain biking in wet technical trails. As such, the more challenging the terrain; the more powerful and wide the beam should be.
Road Biking
Generally speaking, as mentioned earlier, a road biker will need a light with at least 1000 lumens to light up the road far enough so that the rider can hold a comfortable speed without riding blind.
The more powerful RN models, RAY models, and ALLTY models, which provide 1500 and 2000 lumens will do a great job for the everyday commute or the casual road ride.
Now the faster one rides, the further ahead one will need to see.
Additionally, when speeding down a hill at 70+ km/h, not only it is important to see far ahead, but for safety one should be able to see far enough on the sides of the road to see potential escape lines and avoid sudden obstacles (like, you know, all the critters crossing the road at the last second right under your wheel).
