Yes I know you can get two hardrocks for the price of the light.

Does anyone here at this forum have one. feedback is appreciated.

Or any experience with any type of lupine lighting system?

Do a search over at MTBR.com, several guys over there have them.

yes I have a set.
It's absolutely awesome. a frightening tool to yield on the night ride set.
They call me the Lighthouse because of this light.

Anyways, I' have it for over two years now, It's been functionally perfect for all thattime and the battery capacity is still growing slightly sinceit's only been recharged about 20-30 times in the last two years and I ride every week.

It;s simply the best light money can buy.I fyo can afford it get it!
