I have a KT-1, and have never educated myself that much on all of the SF incan options, but would like to change that. I've been reading some old threads, and am wondering if I have a fairly complete list of the lamp assemblies that will work with this turbohead:

N1 (6 volts nominal) - 65 lumens for 60 minutes on 2xCR123a
N2 (9 volts nominal) - 105 lumens for 60 minutes on 3xCR123a
MN15 (9 volts nominal) - 125 lumens for 60 minutes on 3xCR123a
MN16 (9 volts nominal) - 225 lumens for 20 minutes on 3xCR123a
MN20 (9 volts nominal) - 250 lumens for 60 minutes on 6xCR123a
MN21 (9 volts nominal) - 500 lumens for 20 minutes on 6xCR123a
MN60 (12 volts nominal) - 225 lumens for 60 minutes on 4xCR123a
MN61 (12 volts nominal) - 350 lumens for 20 minutes on 4xCR123a


I'm guessing that the shorter "towers" of the MN10 & MN11 were intended only for the SRTH.

I'm thinking that 2xAW18650 protected cells will work for the 9 volt lamps above, and 3xAW18650 protected cells will work for the 12 volt lamps? I know that Lumens Factory makes some bulbs that are perhaps even better choices, but thought that I might pick up a few SF lamp assemblies if I find any at a good price.

2xAW18650 protected cells will work for the (LO 60 minutes) 9 volt lamps above.
2xAW18650 protected cells will overdrive the (HO 20 minutes) 9 volt lamps above.
3xAW18650 protected cells will overdrive the (LO 60 minutes) 12 volt lamps above.
3xAW18650 protected cells will severely overdrive the (HO 20 minutes) 12 volt lamps above.
AW 18650 batteries can power up bulbs with current draw of up to 3.4 Amp but other brands may or may not be able to handle the spike.
