How do we test bike lights?
I've taken a very real world approach to testing these lights. Instead of trying to test specific lumens or check the specs, I just put them to use. The lights I'm recommending are lights I have ridden with and found to be a good option based on features like price and mounting style. Not every light will work for every situation but if it's here in this list I think it's a good option for using the way as designed.
