I've a few Gaciron lights, cheap, well made and working well, but that's only based on a couple months usage. Mine are lower powered than you're after, but this looks pretty good (untested)
I got the 400 lumen Gaciron light about a month ago and I'm really happy with it. Bright enough for my needs and it's survived several downpours so far.
