I have to admit that I really like the Cygo

But I'm not so sure that sure that simply becoming as "bad as cars" is really such a great thing. My experience suggests that small reflector and small beam patterns can produce the "blinding" without nearing 2000 lumen.

The facts are such that for a given 500 lumen flashlight with a "hot spot" you can and will effectively "blind" someone at 200 yards. But don't be confused.

My point is that "smartly designed" lights and reflectors do not need to be powered up to automotive standards to be safe. And again if you read the original post - the real "need" is in the the ability to swtich from some "blinding throw power" to a civilized, just 30 feet out parking light as needed.

I'm already doing all these things, but I have to have a flashlight and a bike light to do it. And two different battery systems as well -hence the need for this thread.

It's all about control folks - but I agree - more power in urban situations is a necessity......
