The higher power lights put out considerably less light except at higher speeds with either hub or bottle generators from what I have read.
If you look at the cite you linked, there are switching electronics schemes that fix the low light at low speed problem by switching out some of the leds. Peter White says that the Supernova E3-D triple puts out too much light for road use. Not sure if I believe that, but unless it has 3 SSC P7 or Cree MCE, it's only putting out around 300 lumen.
