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.
My lead aren't standard. I use leads that have banana clips on the ends. The wire isn't particularly thick (maybe 16-18ga.) and they are 1m long.
EDIT: I just measured with the stock leads and could barely hit 2.0A.
Further EDIT: I have 2 DMMs, and if I test the resistance of one DMM with the other I get between 0.0 and 0.1 ohm with the banana clip leads and 0.5 ohms with the stock leads.
I tried my X9 with 2X16340 and burned both driver and led. So, because i couldn't find a replacemend led with 32mm board, i sticked an XML with smaller board to the back side of the original 32mm led board.
Also changed driver with KD driver:
Please forgive me due to bad pictures taken by my cell phone :) . Because i don't have a good camera, i couldn't put a picture of throw but, i will show you the picture taken from googleearth which shows the most far distance that my eyes can notice:
And this distance with demaged reflector surface. I dont know what happened to the surface. Is it possible because of too much heat dissipated from led?
if you are asking about X9, it takes 1X18650 already. 18500 is shorter around 17-20 mm then 18650 so, it does not work with X9. STL-V6 has a bigger head, that's why it should be a better thrower if its well driven. What i see about X9, it has different specs from different suppliers. Some can use 2Xcr123 some not(like mine), some well driven but, most not (like mine before changing driver). I hope this is usefull :)
I think you will find the Trustfire X9 is too large, it is only 40mm shorter (198mm total length) then the STL-V2/V6 (~240mm). Considering the STL-V2/V6s have 65mm's more space in the battery tube you may be better off looking for something shorter yet.
My Trustfire X9 arrived today! First impressions are very good, one thing I have noticed however is that it is well focused at about 2m but beyond that a hole starts to appear in the center of the hotspot. The further away it is aimed the worse it gets. Max I have been able to experience this is at about 7m (indoors) as it is too bright outside. I have found that if I unscrew the driver and emitter module a small amount it fixes it (however the hotspot is very slightly larger because of it). Just from a quick comparison of only the hotspot of the beam it appears about twice as bright as my p60 R5 drop-in (textured reflector) and slightly smaller (R5 at 1A). Outside at night this difference will probably shrink noticeably, but I have a KD 2.8A driver on hand waiting to be re-homed.
The white plastic spacer between LED star and reflector may have been mounted upside down. If correct, it should fit (engage with) the reflector bottom and its hole.
