Hey Mr. Underbridge
I use a CatEye Single Shot + that is a rechargeable ... puts out plenty of light for me...I travel a bit on my commute through some dark bike path and find the overall light to be really good. I think I am getting at least 3 hours between charges...I charge it up about once every two weeks.

There is smaller version of this light but I have not used it.
