I'm not sure it will come on with a single AA... or does it..?Is there a difference when running a M31 or M31L on a single A battery setup?

Sure will.I'm not sure it will come on with a single AA... or does it..?
Yes. Thank you. That is what I figured, but wasn't sure, since it really wasn't designed for a single AA.The L will have less output and longer runtime.Is that what you are asking?

I just said that 😂😂😂😂😂
JK.
Hm, my measurements on an M31LL indicate that the driver appears to be constant current from the LED forward voltage down to whatever voltage results in a 1A input to the driver (about 1.2V in this case). So an M31L is probably a bit much for a single alkaline or NiMH AA to drive it into regulation, but you might get lucky with an L91.How it works is that you need a certain voltage to turn on the LED...and in a way turn on the driver.
The driver is going to boost the voltage up.
the lower your voltage the higher your mah is required.
the higher your mah the less time your light shines.
the higher your voltage the more bright your led will be because the energy is more intense.
So a AA will work, just won't last as long and won't be as bright since Malkoff doesn't use constant current drivers.

Constant current is a type of regulation. With LEDs, it results in essentially constant output. The Malkoff M31LL I measured has three operating ranges:Does constant current mean that the LED has the same output until it shuts off? I might be confused. All of thermal's test have every Malkoff's output declining as the battery drains.
Maybe I'm mixing up constant current with being regulated?
it shouldn't be... or at least none of my drop-ins have any visible difference in output while they are inside the regulated voltagewhy would the dropin be brighter using 12 volts, than it is using 9 volts if it's within regulation?
Let's post an interest thread there.exactly. you provided the answer we needed
We need to go rile up the HDS thread.
I guess I'm getting posts mixed up. I thought super hard Malkoff users find the M61 and M91 have higher outputs when multiple batteries are used?it shouldn't be... or at least none of my drop-ins have any visible difference in output while they are inside the regulated voltage
I for one can't see any difference between the 2-3 CR123 and the one or two li-ion outputs, neither in the M61, M91 or the Hound Dog 18650 for that matter. If it drops out of regulation because of low voltage, now that you can see.I guess I'm getting posts mixed up.
