I got 2 of these lights: http://www.amazon.com/Best-Rechargeable-Lumen-Bicycle-Light/dp/B00GJZ015Y/
Slightly more expensive at $40 each, but is one of the best reviewed "Magicshine 808 clones" on Amazon and the seller apparently has some of the best customer service (I haven't had to deal with issues yet, but they did send me 2 wide angle lens for FREE after I emailed them).
Real world test is probably nowhere up to claimed 1.2k lumens, closer to 800-900, which is enough for me now. I might grab another one so I can mount 2 on the handlebars side by side.
Note that many of the higher 1.6-3k lumen lights, even the $100-200 MagicShines, have heat issues when running on high for long periods of time, which could affect component lifespan.
