Other than that, in full darkness on dry pavement with no competing lights, and all my lights turned on including the DBS V2... probably 40mph or thereabouts. Let's call it 35mph to be safe
I have over 2000 lumens available when I don't have lights out on loan, but routinely use only about 1200.
First of all, thank all of you that responded. I was afraid that too many would take this as a bragging right, rather than a safety concern.
Secondly, mechBgon, what light setup do you have that provides over 2000 lumens.
Thirdly, from your image, my view at night is about the same, but reach is further down the road.
Fourthly, the confirmable speed does vary according to conditions. A roadway downhill during light conditions wil be 28 to 30 mph. But at night, max that feels comfortable is 26. And yet, on a MUP, I was riding slow at 16 and that was too fast. Hit something that sounded like a metal fork pinging. No flat, too dark and isolated, I kept on riding.
I can adjust for MUPS and mixed lighting. My original concern was just a general question of what is considered a good safe and yet fast speed at night with good lights.
Again, thanks for the comments.
