Crelant V6CS

LED Flashlights – General Info 18650 Flashlights

Hi all,

I got the Crelant V6CS last week and I love the light. It’s just a hint bigger than one of those C8’s and is *really *built well. I love the UI. Tailswitch for on/off and clearing memory, side switch for bright/dim/off with a single click, then strobe and SOS are accessed with a double click. The dimming and brightening is done with the side switch as well which I thought was brilliant.

My question is… What should the current be at the tail switch? I am running about 1.3 amps.

Thanks!

this is what what was replied to that question over there… i think their output ratings are “optimistic”, but not as crazy as others i have seen

3

Thanks!!! SO my driver is doing OK.

1.3 * 4.2 * 0.85 = 4.641 / 3 = 1.547a to the emitter

still seems very low to me… that is assuming it is being run on a single cell…

5

yeah single cell. I was hoping to get someone to take a current reading on theirs to see if mine was ok. The XML U2 is capable of far better than 1.54Amps.

i have the 7g2cs, i think it is basically the same thing in a smaller package. ill get some readings and post back

back

trustfire flame at 4.04v got a reading of 1.33a at the tail. which according to their formula gets me to 1.52a to the emitter

edit: its not the same exact light, but i think the larger 1x18650 2x16340 lights are basically driven the same

7

Yup, I got the same current reading on mine. Thanks!

i have tried 2 rcr123a lifepos in it… i will do it again right now :wink:
if i remember right it was low(ish) too

done

two rcr123a lifepo4 cells measured 7.18 right off the charger and got 1.52a at the tail

ok then… that formula says i got 3.09a at the emitter.

now watch PPTK or some other electronic whiz come shoot down crelants formula haha

edit: that also does not account for voltage sag. if i assume they sag down to nominal voltage, 6.2v, then i would have 2.75a to the emitter

Actually that on par with basic electronics. If you double the voltage but the current remains the same, then what is dropped across the load will double as well.

So what we have discovered is that the Crelant driver will not push any harder than about 1.5 Amps. Ok, guess I should think about a couple rcr123’s to get this light really cookin’

Thanks for all your help!!!

oh and that 4.04v on the trustfire flame… that was after 10 days on standby. it was 4.17v after resting a week after a full charge when i started the test. but i also used it for about 1 min, flawing my test…

11

Do you have any idea on runtime using 16340’s?

12

i dont, none of my batteries are protected so i usually just charge them up once every week or two. and i try to rotate which light i grab… but its usually the ea4 lately

13

yeah my V6CS is around 1.5a on a single cell…it’s around 2.3a to the emitter on 2 18350’s…I run it stacked…
