Those things arrived in fasttech, the J19 seems to be a serious thrower like fenix tk70 right?
The J20 em comparison with the ak90 appears to have a better heat sink and same reflector, but about light output?
Someone have one of those beasts?
Man that J20 looks badass. I want to know of the head is solid or has a threaded heatsink, I much prefer a solid head like on the STL-V2 3x. Threads in the pic look horrible tho…
The 19 looks awfully floody as most of the reflector is missing, definitely helps with throw to have the outer portion.
I like them 
Right now my big-gun Trustfire light is the X6… now i might have to add a TF milti-emitter one.
My J20 is on the way my friend have an AK-90 I think it was more powerful with 3 batteries than 4 so, J20 should have the same output if not more.
AK-90 is noticeable more powerful than AK-47 with whiter tint.
Nice looking lights the J19 might mod up nice. Easier to mod than the SP03 because of the series vs parallel thing. Slave a dry driver in there and you would really have something.
I wish I knew the size of the driver and if there is extra room and decent heatsinking. It might just work with 3 MT-G2’s and a 9xdriver.
The head of j20 seems short threaded, this improve the heatsink?
I only have multi-emiter light 3t6 and j12, I trying to buy the t90 but I dont know if the reflector have a good balance of flood/throw like x6 (my dream light before t90 :bigsmile: )
I want so much to see beamshots of these monster :_(
Your x6 was dedomed?
Is the J20 able to get much boost out of 32650s to voltage and capacity? Anyone know a good 32650 and specs if so and/or has anyone dealt with 32650s? Bigger batteries may be able to deliver higher voltage for longer but are barely higher mAh from what I’ve seen vs 26650s…just like 26650s should be proportionately higher mAh compared to 18650s…
Do you order one j20?
Dont forget to compare the output and throw 
If this light was cheaper, I’ll buy one to mod but I MUST TO RESIST :_( :bigsmile:
I prefer the TR-J19. It looks better and cheaper than the other.
That J19 is sexy as hell. If it is only pushing each emitter at 2A it is a little disappointing but still good host for a mod.
Here’s a picture of my de-domed X6
Thankyou Rikr
Its a sst90?
After dedome the led, do you realized some loss of spill?
Yes it’s a sst90 maybe a little loss of spill but it was definitely worth it.
A serious thrower, your x6 is driven @6A?
How many meters the tower is far?
To make a truly amazing thrower out of a SST90 with the huge reflector it helps to swap it out with a XM-L2 on copper de-domed. You have to drill out the hole of the reflector to get it to focus right but then you are looking at double the Lux easy. If you put in and XP-G2 on copper and run it at 5 amps it goes up again by a lot but then the light is really pinpoint. I like the XM-L2 de-domed. It blows away a de-domed SST-90. I just sold one and am building an even harder driven one right now. The one I sold is just getting started at 300 meters where most good throwers are getting dim. I’m hoping to hit 500,000 lux with my next super thrower. Fun stuff for sure. I have four hosts on the way, 5 MT-G2’s 6XM-L2’s and an XP-G2 all on octogons on the way, plus some drivers. It should keep me busy for a bit. Oh and I bought the best thermal epoxy on the market and that set me back $40. Shot my budget for the month though even after I sold a bunch of lights.
I do like the SST-90 de-domed too though because you still get a great flood and it throws as far as is really needed by anyone. I have an Ultrafire T90 that I bought from Wallbuys for $77 bucks and it came with 2 panasonic 3400mah’s for free, (Fathers day special) Even at $77 it’s a good deal for such an amazing thrower. It won’t touch the same light with a de-domed XM-L2 for through though so I will probably toss one in when my emitters show up.
dang, i should be hitting u up. i wonder what you got up your sleeve….dont keep it a secret too long …
I’ll order soon lights to mod, the price of x6 is droped and this will a candidate for dedomed xml….
But now I’m dreaming with tr-t90, the reflector seems larger than others and I think it helps with sst-90 (I love high output :_( )
I only need now money for this
I guess these will still have no undervoltage protection…
That’s a big disadvantage for applications which need a lot power…
I would be happier if they would make a long king style lamp with some 18650s parallel, but some in serial too. maybe 3s3p…
Then we could use nice and cheap protected brand batteries…
nice, you will make a review when you received it? I love the external design of the head of the j20
I wish one like this but wit only 2 batteries. with 3 batteries are too long
