Question: Why not list compatible generators?
Document: It's very important to note that this light is designed to be used with a hub or bottle generator. Most cyclists that have hub generators have already bought their lights from the same company that made the generator. I don't know many cyclists that use bottle generators. They're less efficient, more noisy, and wear out the tires.However, if you do use a bottle generator or a hub and don't already have lights for some reason this is a good solution.
poorly constructed and fell apart witin second week of usage. Though I guess you get what you pay for. Have bought the more expensive Supernova
What's not to like?
What other parts are required to operate this light? I recently received as a gift but feel i am missing a Battery pack...  What other parts do I need to purchase....
Unlike some of the other reviewers, I found this item top-notch all around. I do agree that more mounting options would be nice, but I just mounted a short amount of old seatpost tubing on my fork crown and it works great.
This light works good, the spot is kind of small but it does work well. Doesn't have a capasiter to store power for when you stop like more expensive ones which is a bummer but for the price it is a good light. I recommend it if your on a budget but if not, get a more expensive German approved light like the ones from B&M. Google B&M dyno light or go to Peter White Cycles and learn all you need to know about Dyno hubs and lights.
This is a very nice "to be seen" or "to see" light. Highly recommended for those on a budget and commuting or non-commuting bike riders.This Headlight is barely visible in the rain. If you commute in the rain or ride fast, invest in something more powerful.The flashing diodes are bright enough to catch the attention of other drivers.The savings on not having to buy/recharge batteries will hopefully make up for the higher price in the long run.

This is a great light. I was initially hesitant about it because of the mounting location on the handlebar but I find that I prefer it this way. My only complaint is that the switch is rather awkward to use in winter when I ride with mittens. It's possible to get brighter lights but this one is very bright. I have to admit that it just seems cool generating your own light. Never a worry about batteries.
The side of the Headlight has two clear lens/indents that aren't very visible from the side.If you are in city lights, the beam is barely visible on the ground, it's best to use the flash mode but level it up towards traffic or it won't be visible. The flashing lights in flash mode in darkness are visible on stop signs for at least 8 or more long city blocks, it's very good.
