TrustFire X9 - Thoughts and beamshots

Diff Multimeter. Same Camera setting. The difference is the Target, the trees is half as before due to the Tropical cyclone that hit us.

I even feel its much2 brighter than the picture.

It lights up 250 Meters easily, was thinking how people in that Building/factory thought where its coming from.

Tried to do a Video of LD40 vs X9 KD drver but the result is crappy but easily shows the difference in brightness and throw. I think it more than triple the brightness of my LD40.

Anyone know how many lumens the output of X9 with KD driver (AMC7135*8+MCU 2800mAh)?

Thanks

The output of the XM-L T6 should be 850L @ 2.8A

What would be the OTF/ANSI on the X9?

Sorry for too many Qs.

The problem is that this kind of measuring is very inaccurate. You get the right current when the resistance of the tailcap and the DMM is the same, and the DMM is accurate of course. If you use short and thick leads, sometimes you will measure much more current than the real when the tailcap is in the place, because the resistance of the tailcap is higher than the DMM+leads.

Vice versa if the resistance of the DMM is higher than the tailcap you will measure lower values.

So it would be the best, if you could equalize the resistances. But these are very low resistances, and hard to measure.

Do you understand what i want to say? My english is not good.

Should it not be 1120L at the LED?

No, XM-L T6 Cannot get past 1000L

It get's 1000L @ 4.2A

Maybe in Cree's lab @ 0 Celsius with the best samples of T6 it can do better, but that's not real life anymore.

here is the beamshots of BC40, X9 (ebay) and modded X9 with KD driver

kd driver = shits bright lol..

What should I do to see the pictures in post #221? Right click and Show Picture doesn't help.

No photos on post 221

I dislike imageshack. lol It takes too much time.

So you have two X9's Krikstas? You happen to have the tailcap readings on both?

THat driver mod looks impressive! Anyone make a driver swap tutorial for the X9 yet? ;)

thanks fishmaniac for help

Tailcap readings:

X9 ebay 1.5 A

X9 KD 2.7

Are you sure those are two different X9? Man you sure are fast, both photos taken within the same seconds of 26th minute of 19 PM. And an exact perfect match on the hotspot? Looks like it's medium then high on the same X9. Great job I guess.

well i am sure they are different :) difference is 16 sec maybe it looks fast on paper but in reality it was quite normal

Is there a link to the 3 mode mod for this driver ?

It's here:

You can leave the PCB connection of the leftmost star in place. The connection of any other star will take precedence.

Thanks

Has anyone measured 2.8A using the Nanjg 105c (8xAMC7135) driver?

I see someone got 2.7A.

I just tested to make sure, and yes, I get 2.805 amps.
