I have a number of Dorcy's, but no Luxeon versions. I do have a SL Jr. Lux. Knowing what I know, I'd get the Jr. It's inexpensive, well built, rugged, regulated and uses either alkaline or NiMH cells. Nice broad hot spot with lots of spill and not too bad throw either, up to 100 ft. or so. Nice clicky tail cap too. Just a bit firm to click for some.
