Got any prices on those things?
The one thing all driving lights ads fail to address is that driving in the bush and driving on country roads is not about how far you can shoot light, it's about how they are set up to show you what you are at most risk of hitting. Frying a big red into submission at 1000m is hardly useful if they don't give you the right light to see the big red that is on the side of the road at 30 meters because the one at 30m is the one you are going to hit, the one up further is likely to have moved before you reach it unless you are driving like a moron.
Using spread beams does go a ways to improving the usefulness of a light but from the point of view of someone who's done more than a million kilometers on country roads at night it's not about the brand of lights it's about how they are used which protects you the most.
Can't help but wonder if the "buy in singles" makes the price a bit unrealistic given they way they are talking them up and anyone can sprout lumens to make a light sound good (back in the 90's it was candlepower) but they do look interesting if the price is reasonable.
