Yeah, I may just end up making my own. Are there true 5W Luxeon stars available yet(with focused beams)? I think that would be a rocking system, especially with rechargeable Li-Ion batteries. Provided one could weather proof-it, and use off the shelf alkalines as a back up to a discharged battery pack. I would want stable light output for 8 hours, as opposed to high light output for 2 hours (then waining light through discharge).
