Here's what a 900+ lumen setup look like.

The red bucket is at 20 metres (65 feet).
The yellow bucket is at 50 metres (164 feet).
The hi-vis jacket is at 100 metres (328 feet).
Even yours is a little weak

4500 lumens



I don't have the same distance checks but I can see reflective signs from up to 7 blocks (640 m) away. I can also see pebbles, glass, potholes, rocks, etc. under street lights with traffic next to me at a nice comfortable 40 or 50 feet. No washout from other sources.

And 40 to 45 mph is no problem
