Like Djozz already said, not a good idea at all. These red LEDs have a very low forward voltage and are way more sensitive to heat and overcurrent than SST-20 for example.
You could try using a 10440 3.2V LiFePO₄ battery (if these exist) but still the odds are quite good that...
In for two. Thanks!
Interested, thanks Lux!
okay thanks for answer, i realized it was kinda a stupid question afterall 
im used to the olight i3t it can run 10440 so ill stick with it then.
Some statistics per today...
78% fulfillment rate of Sofirn's MPQ,
96 people interested so far,
156 pcs accounted so far,
equals 1.63 Sofirn C01R per each member :-D
Please add 2 more to my original post #66
i am interested in getting 1!
One for me in each tint (if there are more than one).
For now, I would count this as one piece since I cannot guarantee that Sofirn will be offering two red tints.
Bitte, leg’ mir noch einen drauf. Danke 
Met het grootste plezier, Henk4U2. :-)
Im in for two
That would be much floodier than the SST-20 C01S right? It sounds like a nice substitute for the discontinued floody C01.
Count me in for 1. Thanks!
Don't be shy djozz, you know the driver blows up… ;-)
Yes, LH351D is bigger in terms of the LED’s die size, resulting in a floodier beam.
OT:
Some time ago someone here posted a source for honeycomb optics. Along with the SST-20 @2700K…
…it is a nice warm and floody light. Sofirn should offer this TIR optics as option.
also what will the color of host be, same red as previous ?
I try to get us a different host color (see two designs in the OP #1) to have more diversity with regard to the C01S.
In for one please…thanks!
