Another type of soldering paste. I don't know how to tell if one is better than the other.

I had this in my cart. http://www.fasttech.com/products/1261003
Anyone noticed broken tab on all three lights?
Good catch!
LOL! Yeah, that might indicate a consistent weak point in it’s design. 
The paste in the first link is just flux. The second link in your cart is actual solder paste (Alloy：Sn63 / Pb37).
But how much of that output can we actually see? I know these things tend to put out a lot of IR.
That’s just it. We need someone who knows more about lasers to chime in.
They tend to come with IR filter, AFAIK.
i just saw the laser that’s used as a reference for the swedish meter. and helped verify another laser that had been sent in for calibration. unfortunately i don’t know much about lasers, but i might be able to ask the researcher that i worked with about the lasers.
also i have to add that i made an order 20th august that still haven’t shipped. i opened a ticket about it some hours ago so let’s see what they says about that.
Several interesting Singfire lights.. Im sure someone will make a proper post about them here.. Until so, here are a few:
Singfire "Rook" 25$
12 XM-L light 72$
7 XM-L light 52$
TR-3T6 clone 31$, okay, maybe not that interesting but it looks like it have the original driver from STL-V6 (which can do 5A+ to single emitter when modded and also change between 2 modes if you short the middle and outer ring)

There are also some more LG batteries. They are cheaper as the old LG batteries, which FT sell. I don't see a battery box on the picture of the new LG 18650 3000mAh. Important: They are unprotected and you need a charger, which can charge up to 4,3V (2800mAh version) or 4,35V (3000mAh version) to get the full capacity. HKJ have tested both batteries full charged and with only 4,2V.
LG 18650C1/C2/C3 3.7V 2800mAh Rechargeable Li-Ion Batteries (2-Pack) flat top / unprotected, full charged 4,3V - HKJ test. Price for a pair $7,77 (with BLF $7,38). My link - non-aff-link
LG 18650D1 3.7V 3000mAh Rechargeable Li-Ion Batteries (2-Pack) flat top / unprotected, full charged 4,35V - HKJ test. Price for a pair $8,89 (with BLF $8,45) - the same batteries with a box cost $12,82 - weird. There is not a note like as-is. My link - non-aff-link
2200mAh LG for 5.63$
I know that this isn't a product but click here.
It's a suggestion I opened so that we don't have to scroll through seven dozen mobile USB chargers to get to even the Pana B's.
If it doesn't bother you, don't click.
I voted! Currently on page 13:

You can use “not” to exclude items, e.g.:

I see it doesn’t work very well. >.<
Hahah, should also be able to vote within the page.
I guess that's for another suggestion. ;)
Suggestions really need tidying up. There’s even copyright claims! >.<
It's hilarious how they ask FT to 'please bear all consequences'.
Didn't realise they take their IP so seriously.
Singfire 1XT6 Cree XM-L T6 3-Mode 3x14500
Looks like 3 x 14500 version of the Sky Ray King, but website says 1 x 14500.
It just has one led and 3 14500, it’s a rook style/copy
Search rook and you will see what I mean.
