From 10 ft they're just as blinding as the new LD1000 blinker. From 250 ft, the difference can be seen. From 1000 ft, a regular blinker, even the LD1000 is just a pinpoint of light while the niterider's a huge spot.
Anyway I took some pics at work today from about 250 feet. The thing dangling off the left side of my handle bars is the planet bike 3-LED helmet blinker on solid. The sun-like glow's the 19-LED niterider.
It runs off an 8-AA battery pack with a 9V connector but I can also run it off a 9V battery. 24-hour battery life vs. 2-hour.
