Since you like to use peterwhitecycle's exaggerated marketing speak and overexposed photos (one of your photo came from peterwhite):
headlight beams from Peter White Cycles. The beam photos shown says Eyc is not that much different despite the "rated" lux.
In real life, those B&M lights are washed out when the road is wet and light intensity isn't high enough when going downhill at 60kph. Supernova E3 Triple or Exposure Revo D would be the light for that job.
For "bright lights" as per the OP, dynamo lights (other than Supernova E3 Triple, Exposure Revo D, maybe the Cyo Premium) ain't gonna cut it.

Shaped beams are overrated. A very powerful light (regardless of it being a flashlight or a dedicated bike light) makes a good vehicle light.
