I think the person that wants to use a good light like that on a 12v or other higher voltage DC source that is not an e-bike is quite rare. Most people that are going to want a high output DC light will be using a Li Ion battery pack with it. Or, maybe like the light I posted a photo of above. power a USB light with a power bank.
