Lumens are a measure of the total amount of visible light from a light source. The higher the lumen rating the “brighter” the light will appear.
Plus is a super-bright rear bike light that can be mounted on your bike or clipped onto your clothing, helmet, backpack etc. Equally impressive as a primary or secondary bike light, Plus is perfect for commuters and road cyclists alike.
