The Lezyne Deca 1500 XXL claims to be the finest high-performance LED cycling light out there, designed for all forms of serious night riding. First things first, I need to explain that this isn’t a light to help you be see when you are cycling from work in the winter - this is a light that allows you to see the road and surrounding area whilst night riding. Anyone who lives in the countryside can appreciate how dangerous it can be riding in the dark; one pot hole or rock on the road can send you flying into the undergrowth when travelling at speed.
