First things first, if you want a cheap generic light like the MagicShine then don't pay Magicshine prices and instead get a generic light that is priced like Magicshine should be; see: Amazon.com : Bright Eyes Rechargeable 1200 Lumen Bike Headlight : Bike Headlights : Sports & Outdoors Keep in mind that these generics or Magicshine way over estimate their lumens, they're closer to about 1/2 the rated lumens.

700 lumens is more than enough to see the road with, I run my lights most of the time at 1/2 that power and can see the road just fine at 20 mph and I'm old so my vision isn't as bright as it was when I was younger. Here is a decent comparison of different lights, only wish they kept the test area the same instead of two different ones, anyways see: 2014 Mtbr Bike Lights Shootout: Tunnel Beam Patterns - Mtbr.com

However in my opinion this light, even more especially since it's on sale, is the best light for the money: http://www.amazon.com/Philips-SafeRi...llips+saferide I own this light, the only flaw is that it has no flash provision because it was made for Europe where flash is not legal. This light is way over built compared to other lights, the body is thick aluminium, the clam shell design is very solid so much so it's difficult to get it open or closed, the power switch feels solid and not plastically; it features a ring around the perimeter of the lens that glows so it can be seen from 90 degrees, it uses 4 AA rechargeable batteries so in the event the batteries fail to hold a charge you simply buy new ones rated for at least the same amp hr as the originals, completely waterproof thanks to pain to open clam shell design. Phillips rated the light to be able to run on high for 2 hours which while only 220(?) lumens it uses aimed optics so that the light on the road is over 1000 lumens equivalent and no light wasted lighting up tree tops, and up to 8 hours on low which is where I use it most of the time because the light is bright enough on low; after 2 hours running on high it auto switches to low and will run for 2 more hours after that; Philips battery life estimates are right on, it's exactly what I get out of mine.
