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.
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
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…
How does the UF 7t6 compare to the J12 or J18? Kind of interesting it’s not called the 6t6 given it has 6 emitters (even though product description says 7…).
So, would you say it’s better/worse build/tint compared to the trustfires? Thinking of getting a super-flooder and would appreciate some comments, thanks.
WOW! I have ALWAYS liked the feel of C cell Mags. This one looks REALLY interesting. I also saw that, for another $9, you can get a tube for it that will fit 2x18650. So if you have both types of batteries, this might be a REALLY good way to go! You could use C cells if you want runtime or a light that can double as a weapon. Or, if you want something smaller, switch to 2x18650. Either way, another nice thing about this light is that you don’t have to worry about failing battery holders.
