Hi susuman,

It is HA. It comes with P60 but no box. 2 surefire batteries included. PM replied to.

According to bigchelis from CPF
The Leggion II SST-50 did similar OTF and is driven at similar (3.5A) current, so now Catapult V2 is not alone.
Bigchelis  other tests with SST-50 lights showed they perform 500 OTF at 2.5~3A .
Catapult V2 driven at 2.2 ~ 2.5A , but to get things really interesting you need to push these to 4.5A~5A.
If SST-50 driven at 5A , Heat Sink will be a big problem .

Thrunite advertise the MAx LED lumens is 1000 lumens from the spec of luminus SST-50 .
When tested , the OTF Is 600 lumens . Thrunite never advertise OTF Lumens .
A bit dissappointment with the output but at least Thrunite didnt cheat .

Hi Guys,

Anybody interested in a mint Surefire C2 Centurion? I am selling just the host and bulb it came with. Body is not bored. Twisty tailcap.No dings & scratches. Used for less than 10 minutes together with the Linger R5 Special. Drop-in not for sale. I'll include 2 original Surefire batteries.

It's the one in the middle.


Asking for RM350 RM330 shipped PosLaju to your doorstep.

First to reply to this post gets it. I can ship this tomorrow.

Cheers,

Lightjunk,

What's the difference between HA & BK? 

How come I missed this one.

SOLD to susuman  . Have fun with the new toy    .

Actually I think the Catapult V2 is driven at 3.5A whereas V1 was at 3.0A

bigchelis test 1.9A at tail .
My friend test 2.1A at tail .
I not yet tested cuz my V2 still on the way to M,sia .
Will test when i receive maybe tis week .

Bro jchong , u can test it with multimeter .

Just note that tail current and the emitter current is different.

Fully regulated emitter current will be like the manufacture claimed, constant at 3.5A
But the tail cap current may be less if uses 2 cells, and it will increase as the voltage of the battery dropped.

Just FYI, record the voltage of the battery (or total of the batteries ) when measure the tail cap current, then multiply the current drawn, you will get the waltage (Watt), this is more reliable way to compare. Anyway, actual wattage to emitter is less (driver circuit take some toll on it (efficiency))
Just my 1 cent

Just FYI, record the voltage of the battery (or total of the batteries ) when measure the tail cap current,

Thanks 

The catapult is 2 cells? So it pulls 2A from the tail cap, it will be around 16W  (assume battery was 8V and Current is 2A). if the SST50 is 3.5V claimed by manufacturer, at vf 3.7V (guess only), the SST50 is around  13W. So it is pretty normal for the current at tailcap you stated above. The different of 3W is the loss in efficiency .

SST-50 at 13Watt .
OTF 600 lumens
Tat mean need to pull at above 4.5A to get more lumens .
But heat sinking will be a big problem 

Going by % terms, I guess the V2 is as claimed. ThruNite claims the V2 is about 11% brighter than V1 (1000 vs 900 lumens). From selfbuilt's numbers the throw is 9% higher and ceiling bounce is 9.8% higher.

But the disappointing thing is that in absolute terms the OTF lumens is only 600 (vs 1000 as claimed). So ThruNite's claim is way overstated. This is not good.

Didn't I post somewhere earlier that Thrunite's claims are all max emitter lumens? You should already be aware of this.

In my book, this is a manufacturer I'll stay away from. No different from Super ultra spider Fire and 280 lumens from a XR-E Q5. Sad..

But that's just me, thrunite is of course not the same as the fires but to me, how a manufacturer rates it's product tells me a lot about the manufacturer. Just my preferences. =D
