How many lumens should my bike lights be?

You've seen the term lumen and you know its something to do with lights but what exactly does it mean. In this article we'll look at what lumens are, why they matter when buying bike lights and just ho many of them do you need.

What is a lumen?

The lumens is a word borrowed from physics. Lumens are a measure of how much light a light source emits. In the case of bike lights the light source is usually an LED or set of LED's.

The more lumens you have the brighter the light; fewer lumens means it's a dimmer light. So surely we just need tons of lumens and everything will be great. Not quite. There is a bit more to it than that.

Why do lumens matter?

Yes they do however it also depends on the ambient light conditions and which mode you are using. A 10 lumen rear light with a flashing pattern can be more effective than a 80 lumen solid beam at getting you noticed.

How many lumens should my front bike light be?

For general road use between 400 and 1000 lumens is recommended. For off-road use or unlit roads 1000+ lumens is advisable. Just make sure you're not dazzling other road users.

How many lumens should my rear bike light be?

A rear bike light can range from 5 lumens up to 300 lumens. Remember your rear light is about being seen rather than lighting your way. Look out for flashing patterns and breaking modes rather than a super high lumen rating.
