I think the DIY halogen gave out the most light, WAY better than the P7 setup, but I started to get sick of the battery pack and wires so I made the move to dynamo power. The supernova is bright and has lots of light, but since it's such a narrow blue beam (versus the warm yellow halogen light) it seems a little darker at first. I don't feel like i'll outrun the supernova, even though it seems a little darker than my old halogens.


Unless you're really opposed to doing a little soldering (or I guess you could crimp it) i'd go the DIY halogen method > P7 > MS with battery pack.
