4. The different fixings of the lights

There are two units of measure for the intensity of a bicycle light: Lumen and Lux. The lumen (lm) is the unit of measure of the efficiency of light; or the quantity of energy emitted by a source in the form of light radiation. It therefore measures the power of a light source. As for the L ux , it also measures the efficiency of the light but per unit area, that is to say the illuminance. 1 Lux = 1 Lumens per m². Everything is explained in our guide on Lux and Lumens .

difference between lumen and lux

If a cyclist rides on a well-lit road such as in the city center occasionally, a 10 lux bike headlight is the recommended minimum. Note that in town on a well-lit road, the 10 lux allow you to be seen but do not really provide better visibility for the cyclist. For poorly lit roads , it is best to equip your bike with headlights of at least 20 lux .

Here are some benchmarks to give you an idea of ​​the light intensity:Here is a pictorial example of the different light intensities (Busch Müller images):

Warning: you should know that Lux and Lumen alone do not define the performance of a fire. Indeed, it is necessary to take into account its whole, such as the width, the depth, the anti-glare or the precision of the chiaroscuro limit.

Also important to know; although bicycle lights are part of the obligatory signaling accessories in town by bicycle, no details are given on the power of said lights. The only restriction is that the fire must not be dazzling.

Choose a Led / diode or bulb light?

The advantage of a light with a conventional bulb is that it offers significant lateral visibility. And if you are driving on poorly lit roads, halogen bulbs are more efficient than simple bulbs. Watch out for these types of fires that consume a lot of energy. The duration of autonomy decreases sharply if they are powered other than by dynamo. To replace your conventional or halogen bulbs:

There are also lights with LED / diode (Light Emitting Diode, or LED) more efficient than the old bulb lamps. The advantages of LED bicycle lights are as follows:

A powerful light
Energy saving
A long lifespan.

These lights are sometimes equipped with reflectors and allow both seeing and being seen. LEDs also offer ideal power for more common use, and do not require changing the bulb.

A diode / LED light allows you to be seen. It is interesting, for example, to install a yellow-orange LED light on the back of your bike. Indeed, it allows the cyclist to be visible to other road users, in addition to being economical in terms of cost and energy. For a front light, it is advisable to use a yellow-green diode light .
