It's hard to tell how good a bike light will be without seeing the brightness for yourself. That's why we braved the cold Autumn air to put together this helpful lights comparison guide for you. You can see how bright each light is and compare key information between products such as output, weight and run times. For complete visibility on the roads, check out our rear light comparison as well.
The bike lights were all tested at handlebar height (one metre) and using a manual setting on a DSLR camera that was selected for its consistency. The first cone was placed seven metres away from the light unit, with two metre gaps between successive cones. The final set of cones were placed 45 metres away from the light unit.
To see the comparison data, simply drag a light into each box below.
