Socalrider posted a link about the C8 from Shiningbeam in another thread. I mention it because:
-It's waay smaller than your Maglight, but roughly double its output.
-It's an adjustable beam. You can experiment with beam pattern to dial in whatever works for you.
-It has a usable flash mode, so can act as a "to be seen" light.
-It is relatively inexpensive ~$25, so if you think you could use more light, get another. Get a charger and some 18650 cells, the lockblocks, and you still won't have spent $100.
