hso, I guess it also depends on what you think of as "inexpensive". The last couple of (Nuwai) flashlights I linked are on sale for $8 and $15, IIRC. Battery Junction usually charges a little over $8 for shipping, but if you buy a few other lights...
I personally am happy with any light with decent spill and throw that has at least 30 lumens, as a primary EDC light. Anything much over 100 lumens is actually TOO bright for many close tasks, in my opinion.
Of course, one always has the option of carrying a very powerful primary, say a
SureFire G2, and a much smaller backup/task light, like the adjustable output
Photon X.
There's also no excuse for every one of us not having a
keychain light. Therey're just too small and inexpensive for there not to be one on every member's keys.
...444, I own...um...5 SureFires, I think. In general, I agree with your assessment, but I have an L4 that needs to go back to SureFire
again. In fairness, I am not the only person who's had an L4 failure, and I'm not aware of other SureFire models with similar problems.
