That's what the Cygolite Hotshots do as well as the Dinotte 300R that make them so intense.
That doesn't make any sense. Lumens can't be measured by lumens per square area.
Lumens is the total amount of light put out by the light. To measure it they use a special integrating sphere to collect all the light.
Lux is lumens per a certain area, to measure it they point a lux meter at the middle and record the intensity.
Typo?
