Nice!
13amps? What are you using to measure the amps with a DMM?
UT210E clamp on a 3” piece of 12gauge wire.
I take that back. Just tried a fresh(er) off the charger, new VTC5A (only 2 charging cycles on it) and got 17a.
The first current test was a 30q after I adjusted the a6 firmware to 5 modes and memory on, then shined the light around the room a little.
Just built a 21700 C8F 3v 50.2 Triple……in a word,STUPID!
Using the stock UTORCH C8F driver it’s pulling 23.8amps for 7036lms. on a 30T at 4.0v
Nice, awesome results guys. Keep us posted if you get any failures.
I want to put one (sliced) in a lightweight thrower like an olight M2X. It would make a nice compact high output thrower. Too bad there are no inexpensive hosts like that…
17amps is 70.2 territory WOW! Maybe your UT210E needs a new battery?
Wow, and with the stock C8F driver...
I just took apart my X9 w/SST-40's - driver is not so upgrade-able - 29 mm diam with the e-switch driver mounted and just 5 mm clearance above the driver in the pill. For me this is do-able with a sandwich driver on a thin 0.8 mm OSHPark 17 or 20 mm driver. The 20 mm driver has the advantage of a lower height MCU since you don't have to bend the pins. I could epoxy down the piggyback driver to keep a low profile - did this before. Or -- could use the stock driver - checked it and it's pure FET driven, uses our std resistors on the FET gate (100K to grnd, and 10 ohm inline instead of 47 ohm we use).
The stock light does 5440 lumens at start on a LK 26650 and 40 kcd, 15 amps at the tail (clamp meter), and with stock springs, but appear to be IOS's BeCu springs.
The Nightwatch IRA would be my pref for a single LED host - heftiest single LED, single cell host I've seen, plus with a very thick copper shelf built in.
For the 17A, that's expected, least for me. 4.25A per LED, should be ok.
17A sounds about right.
You might be thinking of 6 volt numbers. If a 6 volt 70.2 can pull 20 amps then the 3 volt version would be 40 amps. So 17 amps is well below the range of a 70.2.
I don’t know if it’s a coincidence or what, but a few of the 50.2 output tests seem to stop at 6 volts and 12 amps. So in theory you can get up to 24 amps at 3 volt on a single 50.2. You need massive cooling, though.
Oh, maybe this should be Sofirns next production light! :partying_face:
Yeah gotcha, been a long weekend and day….it all is clear…yet fuzzy…if you know what I mean…
Yeah it’s the stock UTORCH driver, 18awg driver spring bypass that is it…. was going to swap the FET to an Infineon…but why waste it, this light gets stupid hot fast…
Awesome Kawi! Which optic works?
I have asked welight about the availability of the 3B tint on 16mm & 20mm MCPCBs, awaiting response.
These look good though 
Well for the most part triples/quads are dead in smaller lights unless you want a high CRI light.
Amp readings aside, the heat is in the same category, IMHO, as a triple XPL s2+ running a fet driver. It’s way too much for a useful light. I should have grabbed some more on 20mm boards for use in a C8 or maybe even an l2. I grabbed a bunch of 16mm thinking of smaller hosts.
Right, I was thinking about putting one in a ArmTech Doberman, no chance now, but it would make a nice furnace, heater, hand warmer, heat my soup up when I’m out on the ice fishing, just turn it on and stick it in the container, a minute later, when it starts to boil,remove and replace battery? :person_facepalming:
Kaidomain has the 3V XHP50.2 too:
That's interesting. They must have a Cutter connection or another special CREE source.
Now we have to wait for BanL to get the 5000K version, if he can. I don't see any drop in Cutter's stock, so maybe BanL has another source.
Interesting.
Still no major electronics provider offers them but they seem to pop up all over our place…
