TrustFire X9 - Thoughts and beamshots

Lol. Will try to post beamshots later tonight.

eargerly await'em

I only checked with one 18650 and it shows 1.4A on the multimeter.

Mine came with a limited warranty from Ultrafire, and in the data sheet, it said it can be used up to 8.4V,

anyone else received this same data sheet?

I will probably replace the driver for the Kaidomain one, but it would be good to know if it really can work at 8.4V, and also would love to know if being that way trustfire will launch an extension tube for 2*18650 like the X8's.

Mine also shows that it can be used up to 8.4V, never tested as I dont have any Brand new CR123 and no 16340 batteries.

I bought from pandamimi and paid $39.99.

In her ad she claimed 3000mA draw.

It looks and feels nice except that the Trustfire Logo is crooked.

With my new and better dmm it tests:

2.8A on High with Xtar 2600

2.7A on H with Tenergy 2600 protected flat top

2.4A with Trustfire 2400 Flame

2.0A with Ultrafire 3000

With these batteries it never gets more than a bit warm.

I tried it with a pair of CR123A batts from Battery Station.

The flashlight works fine and gets hot within 10 seconds. After 5 minutes I switched off. I then tested all modes and they worked fine.

Switched on and off and retest modes 3 times, all OK.

Dumped the CR123 batts and they were quite hot.

Brightness with the CR123A was barely better than with Xtar or Tenergy 2600 but it drew 3.8 amps vrs 2.8 with Xtar and got hot fast.

I will not run CR123A again.

You were lucky stevetexas, you go twice amps than mine, that's the problem of playing chinesse lotto hehe.

It is quite cheap for the general quality, so I don't mind changing the driver.

Here's some comparison shots

So i wanted to test my x9 using cr123a primary's. Here's is what i got: 2.55A, 1.15A, .27A

Edit: Its day time now. Test it in my dark garage and WOW it is a lot brighter, i was getting 1.3A using a 18650.

Here is my hypotheses. The crooked logo run of X9s draw 2.8A. Yavi, is your logo crooked or straight? Not a high probability on this one but you never know with these lights.

Hey Ian, so I guess you got a new multimeter or used different leads? Cuz you said it was 1.13A before.

Looks much brighter than your previous pic! Same camera settings right? I'm still green. ;)

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.
