I don't know about the Malkoff but I last heard that Malkoff drop-in does not have two stage or multiple stage power settings. That alone is a big turn off for me. My passing criteria for any LED setup now is at least a duo output configuration. Maybe there is one from Malkoff which I have not heard of but please point me there.
I don't know where this discussion is heading to but the E2e tail caps are indeed lock-out tail cap. I am talking about running the IMR setup in MY E2e. Maybe you are referring to E2 but I have not owned them before and can't comment on the E2. As for the G2, I know that the early series are not LOTC. I have them and owned them. So I am not too sure who is confused here but just for your info, I have 21 pieces of Surefire incandescent lights from the E1e to the M6. Other than the older G2 and the newer clickie switch on my black E2e, all my Surefire incandescent lights comes with lock-out tail caps. Twist to lock-out. We on the same wavelength here?
Anyway, our discussion here has got to do with the E2e running IMR bulbs and IMR batteries configuration using the lock-out tail cap as advised by Lumens Factory. I am not talking about any other lights other than the E2e so please, with all due respect, stop confusing everyone here by placing G2 into the picture.
This would be the end of this topic with respect to the thread starter. We are going into the off-topic zone. My apologies to everyone.
