With the arrival of good weather, more and more people are choosing cycling as a mode of transportation. However, it's important that along with this, safe cycling also plays an important role. One of the most crucial elements for this is the appropriate bicycle light, which helps us to be more visible on the roads, thereby contributing to our own safety and that of our fellow travelers. In this blog post, we will examine why it's important to use high-quality bicycle lights.
There are a few things to consider when choosing a battery, so I've summarised the main points in a few words:
One of the most important aspects is the size, so choose the size of battery that the manufacturer recommends for the device, because if you buy a smaller or bigger one, it won't fit, it won't reach the terminals or it will rattle, so if it says 18650 size, for example, then buy that. What else do you need to look for to choose the right battery??
Perhaps the best known measurement is luminous flux, which is measured in lumens. This value shows the total power emitted by a light source weighted by the Λ curve. The Λ curve gives the sensitivity of the eye as a function of wavelength, as the human eye is not equally sensitive to all wavelengths. This may sound complicated at first, but it is easy to understand with a concrete example: for two identical 1 W light sources, if one is green and the other red, then even though they have the same wattage, the green one will have a higher lumen output because the human eye perceives green "better".
