I'm wondering whether to get the Light & Motion ARC Li-Ion Ultra HID
or the NiteRider Moab HID/LED. They're both the same price but the
NiteRider burns over 50% longer at the same highest level of
brightness (if I'm reading the specs right -- in which case I'm
surprised Light & Motion haven't lowered their price at all; also, I'm
not sure what it means for the NiteRider to be "HID/LED" [according to
performancebike.com, anyway])....


TIA, folks!
