If you don't care for the XR-E then this is not 4 U but here U go anyways ;-) This is at least D size cells.
Also with side switch from DX
Manafont has some more smallsuns
I know the first is not a zoomie but I think these are really cheap and could always be given to friends.
How many lumens is the 5C XM-L? Runtime? Any beamshots?
Thanks for the heads-up!
I don't know and no.
But a conservative guess would be ~ 750 initially and then going down. To me half of the attraction would be whether it can drain the batteries properly, maybe even beyond 0,9 V. I have a few lights that will do that and I love that when I run them on primaries they will not turn off until those batteries are EMPTY.
If it has a decent spacing between high and low then the runtime on this should be very good actually. 5 C cells are around 1,6 V initially and then down to say 0,9 V for a total discharge of about 4000 mAh (going by memory here so please correct me if my numbers are off).
Rough calculation of power is 4000 mAh * (1,6-0,9) = 2800 mW
5 cells => 5*2800 mW = 14000 mW
2,5 A initially to the led and 80% efficiency would give 3100 mAh consumed at the batteries and with a 3,2 V Vf of the led it would consume 9,9 W giving about 85 minutes of runtime on high. Actual numbers would be higher since I don't thing the driver will hold that so maybe 3 hours until the output is half of initial turn on. On low the output is probably something like 30% of high so the runtime would be 5 hours,
But this is all academic since I know of no reviews, I dont have the light and I have been waiting for a review to pop up but alas none has.
But the size of the head probably lends itself to a good balanced beam with fair throw and fairly bright flood of a big area in front of you.
You know what? I may have just talked myself into getting one to see if I am totally off with all my speculations here :-)
As somebody else already mentioned in a different thread,
the Trustfire TR-J12 (5 XM-L) works pretty well with C-cells
I just stuck 4 freshly charged Tenergy Centura 4Ah LSD cells in mine,
tailcap currents were 5.6A/3A/0.4A on H/M/L
Tube seems a bit longer than some others,
to make reliable contact I might have to add a magnet or some other kind of small spacer
-S
Fantastic - did not realize 4xC cells could replace 3x18650/26650s.
Is the Trustfire TR-J12 the best bang for the buck with C-cell replacement? Any other lights work well with C-cell replacement?
Also, anyone know what kind of lumens the Cs produce as opposed to 18650/26650s in the TR-J12?
mitro had a comment here
and drd here
Only battery tubes for 26650 will fit C-size cells,
if it’s meant for 18650 only it’s too thin (~18mm)
According to Wikipedia C-size is 26.2mm dia × 50mm long
26650 is obviously 26mm dia x 65mm long (nominal, may be longer with protected cells)
so 3x 26650 should be ~195mm long, 4x C-size 200mm long

that is wonderful! if all 3x26650 lights can be replaced using 4x c cells, then heres another option for ya. the skyray 9xml light. but you should wait to see if others can chime in and confirm that 4 c cells will actually fit. if so, this would be the light to go for.
I don’t think it’ll work for all lights.
Mechanically/dimensionally 3x26650=4xC-size,
but if the driver doesn’t support the low voltage of 4x NiMH it might not work.
But it’s confirmed for TR-J12.
I also tried it on a TR-J18 that I have, but current draw with 4xC-size was a lot lower (only ~2A)
so with that one it doesn’t work as well.
Should be receiving a 9x XM-L soon, will see how that fares with NiMH

Anyone know the tint/color temperature of the TR-J12? Is it cool/neutral/warm?
I had the “777” Smallsun.
It threw pretty well and was as bright as you would expect.
I think it was not regulated or something, since it faded pretty fast with Alkalines…
These lights are more than LED Mag Lights…
The TF 3t6 works with 4 AA (same length as C’s). Draws 4A for full brightness in high mode.
Dunno where OP lives but in the US normal stores tend to carry more C/D cell cree lights, like Rayovac “Indestructible” 3c/2D
Correct - I’m from the US and have a bunch of AA, C and D size NiMH cells.
One more question - any other neutral/warm multiple XML lights without PWM (that can use AAs or Cs)? Trustfires seem to have bad PWM.
Pretty much all budget lights use pwm for lower modes. Skyray king pwm is pretty bad on low, too. 200hz. Dry is around that, too.
I just meant why would someone buy a small sun q5 for more than a mag?
Mags are pretty expensive outside the US. Even in the US $25-35 > $17.
which 9xml are you getting? so with the 4xc size on the tr j18, it was less bright than using 18650s and 26650?
Since I just got a light meter
Quick and dirty ceiling bounce measurements in the bedroom
| Light | Lux w. NiMH | Lux w. Li | |
| TR-J12 | 225 (4xC) | 215 (3x26650) | |
| TR-J18 | 90 (4xC) | 235 (3x26650) | |
| UF 7T6 | 180 (4xC) | 190 (3x26650) | |
| TF X100 | 95 (4xC) | 350 (3x26650) | 310 (4x26650) |
| SR King | 210 (4x18650) | ||
| TF 9XT6 | 320 (3x26650) | ||
| TR-3T6 | 110 (4xAA) | 125 (3x18650) |
The TF 9x XM-L I got won’t even start on C-cells.
