Re: Fivemega 3xAW C cell body S.F C head
Thanx for the interesting read. I was planning on using 3 C Alkaline/NiMh to drive a Malkoff M30F. The current set w/ a 18650 doesn't seem to provide enough runtime for me. I forgot about the battery size difference. Will have to find something to fill the void.
Unfortunately, the M30 is pretty outdated by now - IMO the top candidate for the three-cell body is the new Malkoff M61. Compared to the M30, it has a more efficient emitter (XP-G, more lumens per watt
and a lower V
f) and a more efficient driver (buck rather than boost for starters). More output than either the M60 or M30, and a longer runtime than the M60 (& a much longer runtime than the M30). The M61 is replacing the M60, M60F, M30, & M30F in the Malkoff lineup, for good reason: it stays regulated down to a lower voltage than the M60, and the regulation of the M30 was always kind of 'odd' - not really regulated at all in the normal sense (the M30 driver has been documented to draw
more current as the voltage increases, rather unusual).
I've used both the M60 and M30 for relatively low-voltage (1x18650) configurations and sold off the M30 as it didn't really perform as well overall. The M61 should be
magnificent on 3xC (both in output
and runtime), much better than the M60 or M30.
Glad you liked my thread, I've had a lot of fun with those FM 'C' bodies.
Good luck,
