4.5A - what to do... SST-50 or T6 XM-L2?

LED Flashlights – General Info
1

I have a Trustfire X7 that came equipped with an SST-50 of unknown bin. Tailcap current w 3 * 18650’s = 1.53A, so a theoretical 4.59A to the emitter before losses. From http://flashlightwiki.com

SST-50
Bin 1750mA 2800mA 5000mA
G 275-350 440-560 743-945
H 350-425 560-680 945-1148
J* 425-500 680-800 1148-1350
K 500-600 800-960 1350-1620
L 600-700 960-1120 1620-1890
*maximum bin is J

XM-L2
Bin 700mA 1000mA 1500mA 3000mA
T6 318-341 438-468 615-659 1044-1119

Without knowing what bin the SST50 is, this might be a silly question. Should I keep the SST-50 or swap it for an XM-L2 T6? Somehow I think I might need to swap it to find out. >)

XML2 in U2 would get my vote, where did you get your X7?

3

My vote is an MTG2 :wink: if you can get 6 volts and 4.5 amps

Otherwise an XML2 U2 bin :smiley:

The X7 was donated by Kevin from aurabuy.com in exchange for a review. I already have the XM-L2 T6 on a 16mm AL star. Now Im beginning to wish it were on copper. Before I post the review, Id like to compare stock lux numbers vs modded numbers (if there is a real advantage to this mod - which I think most people can easily perform on their own). The X7 host itself is spectacular and shows little room for improvement. Im not interested in dedoming.

Any other opinions on the emitter swap?

I havent taken a DMM to the emitter yet to test voltage. Will the MTG2 survive with the stock driver? Runs on 3 * 18650.

I don’t know for sure, I know that the XML takes somewhere between 3 and 3.9volts. The desired voltage is up around 6.5 volts and VinhNyugen doesn’t know of a good driver for the mtg2, than I don’t know who would.

Here’s where we discussed it

Someone modded a ZY-T13 to use a MTG2 with the stock driver and appaarently it worked, so it might work just fine!

Here is the thread

I saw that (looked friggen awesome! :bigsmile: ), but also a 2 cell light @3.2A. The X7 is 3 cell and driven harder.

I just ripped it apart. 3.051V measured at the emitter while powered on in high mode.

10

I think That would be a nice drive for the MTG2

Thanks for the input. The emitter I have is the XM-L2 T6, not the U2 version. Beyond any differences in tint, I doubt the best set of eyes couldn’t tell the difference.

After browsing through the MTG2 threads, it looks like this emitter is not well suited for throw, unless using a HUGE reflector. Id like to keep this light as a thrower if possible.

Any additional thoughts?

I’d like to see beam shots when your done :slight_smile:

There will be a full review within the next few days.

bump… anyone have more ideas?
