Check out my thread about the NR Solas. You'll find a link in post #3 that compares that light to a PBSF Turbo. Daytime and night time vids and images.

I've read that the PDW lights are compatible with the PBSF mounts (I think they were designed to way to make it easier to attract customers away from PB), and I believe that the Radbot 1k owners will say that their lights are noticeable in daylight. Then again, since they are looking at them, they are going to be noticed...
