Curt stated in his first post that the #8 would be a buck/boost supplying 1 amp to the LED, so we can assume that the other numbers are not buck/boost. The implication re #8 is that it will deliver that 1 amp to the LED with either a CR123 or RCR123. It is looking like the #8 has a voltage regulated circuit, and not CC buck/boost.
