Default Decent bicycle light cost

The Oculus runs great in hybrid mode. With both the battery installed, and a generator to 5VDC adapter plugged into the charging adapter, the light stays lit almost endless at the medium setting, which is already brighter to the eye than most of the pothole spotter single LED lights out there.
Candlepower doesn't have a direct translation to Lumens.
"Lumens" is a measure of how much light a lamp produces in all directions.. "Candlepower" is the intensity of light at the center of a spotlight beam when measured in one direction. Thus, strictly speaking, you cannot directly convert lumens to candlepower.
Candlepower more directly translates to Lux at a 90 degree angle of incidence, meaning straight on. So it can't say what a light's overall brightness is, only the maximum. Thus Candlepower is a useless measurement to determine a light's usable visibility, only how much of your peripheral vision it will take away.


I'll aske again. Will you refund a customer's money if the Oculus does NOT meet their needs? Yes or no.

Cheers
