I had almost the same doubts and restrictions some weeks ago, and I bought some of these flashlights to test them all. Up to now only 2 flashlights arrived, but it’s a starting point. Although my triple XP-L X6 is a light beast, I consider the MH20GT portability and weight nicer.
Even if BLF A6 is not a thrower, maybe it can meets the portability x light output ratio in a very nice way, with its smaller head. I am waiting S2 and A6 to arrive to compare the light outputs of them all.
And I’ll also definetely consider this one when it comes out (I am following it already):
A JAX M8 or C8 mini can do 60kcd when modded with a FET driver, in stock form with the 2.2A driver it does 31kcd. Outperforms the X6 while being more compact and better built, and the SMO reflector produces one of the smoothest beam from the HI emitter.
Parasitic battery drain in a day would be a complete killer / knockout ……… sure it’s not a bad battery I recently bought a Coast rechargeable that came with 2 batteries and one just wouldn’t hold it’s charge whilst the other is fine???
Tailcap lockout is just unscrewing the tailcap 1/4 turn to disconnect the contact of the circuit.
I tried several new Panasonic batteries, and still had the same problem of the battery draining. I may have a defect, but it is still an issue that I don’t like.
