After a huge amount of discussion with several others and a great deal of research, Ive decided to go with 40 x high quality C8 XM-L reflectors that have already proven to focus well. TIR optics simply dont provide the range necessary for my application and a tight spot would be all but useless on the trails. My only concern now is the very likely need to replace my alternator with something that will put out several more amps to power the LED array and HID’s.
