Brightest 2C Mag mod?

[keith p]

Just to let you all know, I did search for this first. I'm looking for a more current answer. All the other threads were quite old.

The host will be a 2C Mag powered by 2X 18650 (AW 2600mAh) in series.

We need a combination of throw and bright spill.

I didn't put this in the LED section as we are open to incans too.

Run time is not a consideration. This is for short burst use only.

Is 2X SST-50s running @ 5A each possible?

Don't know about Incan, but for LED,
I think I am the record holder for building the brightest Mag 2C with LEDs:

#6: Seven XPG R5 on Mag 2C ~2500 Lumen Monster Jr.

2xSST-50 is possible, but will generate much more heat than 7xXPG R5.

The light I made can Run 2x18650, but it'll pull 4 Amp & my Blue Shark
may overheat. Generally speaking, the lower the current, the less energy turns into heat & the more efficient
the system will be. So I did it with 3x18350, pulling 2.5Amp at 12v, ~30W.
The Blue shark is 90% efficient at 2.5Amp (drop to 75 efficient at 4Amp), so the XPG R5s are running at 27W.
Roughly 4Watt each. Also, I think XPG R5 is the record holder on LED efficiency. XPG-R5 at 1A is more efficient than the SST-50 at 5A.

for the 2x sst mod, IMR cells would probably work much better, a 2D mag would probably be best for heat transfer as well.

I agree, but a 2X18650 2C mag host is already in my possession

If skill level is a consideration, you might just want to consider getting a metal reflector, glass lens, bi-pin adapter and a nice little hotwire bulb, like a Philips 5761 or PH7388. That's the least amount of assembly required for a 1500+ lumen torch. It's also the cheapest if you source the parts from Hong Kong.

I don't know of any pre-fab drop-ins for a Mag that compare to the bulbs above or to what you can achieve by hand with LEDs. If difficulty and cost are not a concerns, and you want more than 2000L from the batteries you chosen, then you're in homemade, multiple emitter LED territory. Check out some of the torches linked from the post at the "My Torches" link in my signature for inspiration.

A project like this might be a good candidate:

If you want to build the brightest 2x18650 torch, then you'll have to beat this one (~4500L):
