I have a 0.5-watt PB Superflash that I have been using at night (which works well) and also on darker overcast days. The light is visible on overcast days, and it probably helps a little bit, but I'm wishing for more. Will the 1-watt Superflash Turbo or Radbot 1,000 be eyecatching in daylight, or should I go for something better? I'm trying not to be unrealistic - I doubt that they will show up at high noon on a sunny day. I always use my current light in flashing mode, and expect the same for the new one.

The reason I'm focused on these lights is that I already have PB seatpost mounts on 3 bikes, and I love that I can just have one light in my pannier and stick it on any of the bikes. (I heard that Portland Design Works lights work with the PB mounts, but correct me if I'm wrong about that). It would be nice to have a better light that would work with these mounts, and also keep my current light as a backup.
