Also, I noticed it says 250 peak lumens....that would have to be a cumulative total of all the lights together. Looks as though there are 10 total.....that's 25 lumen per light. It would be interesting to see how that compares to one of the half-watt or 1 watt rear blinkies. Reason I mention is because it says visible up to 500 yards. That's 1500 feet. That's less than a third of a mile.
I agree. A 140-lumen DiNotte taillight should be "visible" from over 4 miles in darkness*, and can definitely command attention from more than 1 mile (according to a co-worker who overtook me on a long straight section of highway at night). If their light array is really producing 240 lumens, it should be visible from a heck of a lot farther than 500 yards. I have little bar-tip blinkies that are visible from well beyond 500 yards, to say nothing of mainstream ones like a SuperFlash, premium ones like a DiNotte, or homebrew alternatives like a
Nova.
A standard bike light can be seen for approximately 50 feet
good catch

*if anyone's wondering why I pick "4 miles," it's because I can see car taillights at that range on a very long straight section of Highway 195 in the dark countryside, and the DiNotte has at least as much power as a car's full brake light
