bullcat, your choice is either a powabeam, or lightforce then
they both have their pros and cons
i have a 11in powabeam here, it is the brightest light ive seen to date, pisses on my lightforce lights, and i have 4 of them. the reason i have 4 is because your better off buying a new unit then replacing the clear lense when they get too scratched, as they nearly cost the same
lightforce lenses scratch, and with the scratches yoru light quality drops, and after a year of use you will notice
i havent used the powabeam heaps, so havent found any niggling bits about it yet, other then its big, and driving a long distance with it woudl be painful due to wind resistance.
