I don't know how much light the Alias puts out but I would figure 200-300 lumens (I could be wrong). You can get a fully self-contained LED light that puts out double that. That is due to the drastically greater energy efficiency (therefore less batteries needed, so can be self-contained). I went the flashlight plus two hose clamp route. Flashlights on average will be cheaper than anything targeted at cyclists. Personally, I like AA lights. I know NiMH have a lower energy density that Li Ion, but they are ubiquitous. (And I have enough rechargeable AAs to take off on a month long trek without ever needing access to a charger).
