How many Lux should a bike light have?
60 Watt Bulb = 800 Lumens There is no fixed agreement on how many Lumens you need for a bike light as it depends on the type of cycling you are doing. As a rough guide we say that: Daytime running lights to be seen in daylight = 100+ Lumens. Urban commuting lights to be seen in town = 50 to 200 Lumens.
