ric4106664wrote a review of Lezyne Mega Drive Front Light on August 15, 2013
I use this for road biking, mostly just in case I get caught out late on a long ride. I was concerned it would be too heavy (can't really use as a helmet light), but it really hasn't ever concerned me and now I leave it on the bike most of the time just in case. Battery life has been great (at least as good as represented) and it is super bright. Only on rare occasions have I run it on full power because it can annoy oncoming people, cars and bikes. But 1000 lumens is nice to have when I am hurrying home down a back road in the otherwise pitch black. I got the "loaded" pack with an extra battery, but have never needed it and rarely carry it. But, again, I still like the option of up to 10 hours of light- maybe I'll go in search of a moonlight double century to ride. (Won't happen.) Mount on my round road bike bars is solid. Only thing I think could be improved is the beam pattern- it is pretty much round but with this much light capacity, I would prefer a triangle shaped beam. Oh, and it is a little slow to charge- definitely have to plan ahead. Nonetheless, I have a lot of hours on it and am really pleased.
