What are the runtimes for FOUR4TH lights using Lithium Polymer (Li-Po) Batteries?
My light sometimes has a slight flicker when not moving?
Because of the auto ramp up and down you do notice a flicker : it’s because the programme is constantly working and adjusting the power output to the LED’s this does change according to the ambient temperature. once sufficiently cooled the light will not flicker and will not be noticeable when riding.
Whats the difference between whit and green LED’s?
White LED’s are brighter than green, slightly harsher and more bleaching whereas green is slightly softer not as bright but you get better definition in single track
