The Phillips light Rekmeyata mentions is exactly the primary light I have. For all that it is nominally about half the lumen count of my old 12 degree beam 10W HID light, it produces equal or better road illumination. It seems a little over bright in the foreground, but from my reading it's better than anything else out there. After installing a 5V regulator from a car USB adaptor the runtime issues are solved, making it a fine primary light. While I wouldn't object to it being brighter, more useful would be to just add some more light to the higher portion of the beam on the road. Of course, after addressing this, adding more overall light would be just fine with me.
