That would be good for the xp-g2, but not the MT-G2. If you ordered the 6v version, I'd look into one of the multi-xml drivers as a good start. After I finish up some current projects, I'll get started on a build with this emitter and keep you posted.
I'd recommend a driver meant for triple XM-L in series. This will put out 9-10v and should be good for a 9v MT-G2. The only problem is you may want more than just 3A (I know I would). Problem with this is the 9v MT-G2 is rated for max of 2A. Your best bet is to hang on, like NightCrawl said, for PilotPTK's new MT-G2 driver I heard he's working on.
Another option for a 6v MT-G2 is direct drive from 2 Li-Ion cells with a resistor mod to drop the current from 8.4v to the low 6V range.
Just in case anyone is looking at this one, the 9 volt mt-g2 is only rated for a max of 2 amps, so a 3A driver would be overdriving it by ~50% already. Heck, the 36v one is only rated at 500ma.
Cutter doesn't even have the 9v,just 6 or 36,this is going to be a real pain to find a driver for.Trial and error will be the way to find out what works best,I,m going to try a 5 amp sst-50 driver@8.4v with the 9v mtg and see what happens.Just have to wait for the 9v to be available.
I think you guys are forgetting the simple fact that measuring the approximate output of an LED by amperage alone isn’t entirely correct.
We can generally get away with it in this forum because normally all the LEDs we use operate at the same voltage, but these don’t.
Volts X Amps = Watts
So, for the MT-G2, it only makes sense that the three versions are as listed:
6V at 3A = 18 Watts
9V at 2A = 18 Watts
36V at .5A = 18 Watts
For an XML:
3.1V at 3A = 9.3 Watts
FYI, because I was curious, they list the MT-G2 maximum output:
1987 lumens at 18.5 Watts = 107.4 lumens per watt
And the XML maximum output:
1040 lumens at 10 Watts = 104 lumens per watt
So efficiency is pretty similar, it’s just capable of a much higher input, thus allowing far more output.
To me, this LED means we now have the capability of a much brighter flashlight in a single LED format. I’m excited.
I fitted this driver in my torchlite build, I get a 3a tailcap reading on two keygos 26650’s (not the best cells in the world) its comfortably bright on high and low is wickedly low considering.
pop over to the torchlite thread by edcplus ti see what we all tried out.
