For years i have been wearing a Fenix LD10 as edc and iirc an LD20 (wich i still have) was my first "serious" flashlight so even if now i am more a 18650 tube user now i still have a special place in my heart for AA flashlights.
I bought the LD12 a few years ago in case my LD10 would fail but could never really get myself used to the "2 buttons" UI so i was happy to find (thanks to BLF !) some cheap LD10-likes
So here we have a quick comparison of :
- Fenix LD12 (left)
- Sofirn SF10 (midle)
- Convoy T2 (right)
Weight with clip, w/o lanyard :
- LD12 : 53g
- SF10 : 46g
- T2 : 49g
Max dimensions :
- LD12 : L= 105mm, D= 23mm
- SF10 : L=97.5mm, D= 20.8mm
- T2 : L=93.3mm, D= 21mm
- LD12 XP-G2 R5 color temp unknown, smo
- SF10 XP-G2 rank unknown, 5500K, light op
- T2 XP-G2 rank unknown, 4500K, very light op
- The LD12 has a crenelated bezel while SF10 and T2 are flat
- The LD12's tail swith is protruding from the tail body so the light can't seat on his back while the SF10 and T2 have recessed tail switch and can seat on their back.
- When removing the tail part of the SF10 there is nothing to stop the clip from sliding (and eventually falling).
- All have lanyard holes on the tail
- LD12 : ON/OFF with forward tail switch, momentary ON possible (and easy), 4 modes (short press on the side switch to cycle) with memory + 2 Blinkies (Dual frequency strobe and SOS, long press on the side switch to cycle)
- SF10 : ON/OFF with reverse switch, 4 modes (short press to cycle) with no memory (always start High), Dual frequency strobe (dual quick/short press)
- T2 : ON/OFF with reverse switch, 3 modes (short press to cycle) with memory (*) , Single frequency strobe (dual quick/short press)
(*) T2 memory is a bit special : if you let the light OFF for more than (about) 5s then it is a "normal" memory but if it is OFF for less than 5s then it is a "next mode" memory
- LD12 : polarity protection, use AA NiMH, alkaline, or lithium primary, NO rechargeable lithium !
- SF10 : polarity protection, use AA NiMH, alkaline, lithium primary or rechargeable lithium (*)
- T2 : use AA NiMH, alkaline, or lithium primary. Despite what some sites might say the driver is not intented to be used with rechargeable lithium (might work but who knows how long ?) and there is NO reverse polarity protection on the ones i got from both GB and AE convoy's shop.
(*) With a 14500 the SF is able to output (a lot !) more light but this as not been tested
Below is a table showing the measured light output (lm) and tail switch current (mA) for 5 flashlights :
- 1 x LD12
- 2 x SF10, the 1st one is the brightest from a lot of 6 and the 2nd one is the dimest from the same lot
- 2 x T2, The 1st one is unmoded while the 2nd one had the current limiting resistor modified from 0.2 ohm to 1.0 ohm

Light output was measured in a sphere copied from Djozz's "fast and cheap integrating sphere" with a Minolta T-10 luxmeter and the setup was calibrated with a set of calibrating lights from maukka.
Current was measured on a verified UT139C, milliVolt caliber and external 20m ohm shunt
All flashlight received a fully charged Ikea Ladda 2450 (known for beeing rebranded eneloop Pro) before the tests
From left to right : LD12 XP-G2 R5 color temp unknown, brightest SF10 XP-G2 rank unknown, 5500K, modified T2 (so the 3 have about the same output) XP-G2 rank unknown, 4500K
The tints on the picture are not exactly what i see, the LD12 look really white while the SF10 is more greenish and T2 something like a light salmon-orange
