Thanks for all the info and pics! Good chart Norm, very informative. The light I keep under the seat of the motorcycle is mostly for emergencies in case of a breakdown. So, maximum throw isn't really that important. The adjustable focus of the scorpion and the spare bulb made it a good choice for emergency repairs, and the little UK 2AAA was a good backup in case I ran down the Scorpion batteries. Plus, they were both inexpensive. Since things tend to get scratched up and bounced around under the seat, I didn't want to keep an expensive light like an A2 under there. So, the TT 2L could probably serve both functions, if I ran down the batteries I could still use the led's to get some light. It's inexpensive (relatively, to a flashaholic) and would save a little space. I'll probably give it a try.
The TL2 and NF2 look like really great lights, but not for this purpose. Are they the same light except for the ring. Botach has the NF2 for $35 on sale right now.
