At the end there will be a summary for those who like only particulars. In each topic I will bold the key sentences, so it will be easier to notice what's the most important. Enjoy!

I've got this flashlight from Convoy's owner- Simon - its's an experimental version, although Simon said it  will be mass produced

In the thick cardboard box was only a well secured flashlight + tactical ring. Everything well protected with sponges.

For those who had the L6, the flashlight does not need special introduction - it is the same decent L6, only with a new LED.

For those who do not know L6:

Generally speaking, this is a large and durable flashlight, with a height of 25.5cm, head diameter of 74mm and weight including cells of 745g ...not suitable as EDC

Beginning with the head:

Tactical head bezel, aluminumAR violet coated lens

- Reflector OP, also possible SMO




- GT-FC40 12V LED, the tint in my unit is cool white, about 5000K-5500K. More about it in the section Light pattern, tint


- Head with substantial fins, really does the job. On the side, the button to change modes (on/off button on the back). It is not illuminated.


- The driver does not have a bypassed spring, unlike the spring in the tail cap.


- The cell tube is long and knurled, which gives a firm grip - people with large hands will like this flashlight.

Unfortunately the batteries inside are bumping into the tube walls. As I checked, it can be eliminated by using stronger spring,

- The kit comes with a metal tactical ring screwed in front of the tail cap. Thanks to it the flashlight does not roll off the table so easily, you can hold it in rather inconvenient way, and most of all it adds +3 to tactical look



- The tail cap is equipped with eyelets for a lanyard, and a forward switch - momentary lightning when pressed halfway, continuous lightning after an audible click. Less popular than the reverse switch, but good for temporary lighting.

UI
The current driver has 3 modes: 226lm - 1250lm - 3415lm. You turn on the flashlight from the back, and change modes with the button on the head. There are no flashing modes, only 3 modes.

NOTE: only my pre-sale version has 3 modes, the target and general version has 4 modes + strobe when double-clicked. The modes are 1% - 10% - 40% - 100%

Runtime
I will soon add a graph showing changing of btightness, now I have the temperatures, and also the brightness at minute 10.
Temperatures:
at 2 min: 40°C
in the 5th minute: 43,5°C
in 10th minute: 47°C
brightness in 10th minute: 1657lm

Charging
There is no built-in charging, so you will need to arm yourself with a separate charger, preferably with 2 slots.

Yes, PWM is visible with the camera, but not observed with the naked eye.

Declared IPX6, so resistance to all kinds of rain, but does not have immersion resistance under water

GT-FC40 12V LED, 5000K-5500K, 90CRI with max brightness measured by me 3415lm. I found such tests, it seems that those are the same diodes, but I'm not sure: https://budgetlightforum.com/node/68899
If so, the diode has even 94CRI

I would definitely recommend the OP reflector version!

You can certainly see that the color is cool, closer to 5500K than 5000K



Despite the large size of the diode itself, you get quite a bit of focus when combined with this flashlight and reflector. I would like to see this diode in smaller flashlights.

ISO200, t2s, f/3.5 sunlight white balance

Picture how the forest looks:

Pictures of L6 GT-FC40:

3 modes are completely sufficient, if you take into account that this is a big flashlight, and as you know, big flashlights are supposed to shine brightly, without playing with some moonlights and other such stuff.

Now I invite you to the clash of giants: 4X18A in the left corner versus L6 in the right corner, heavy weight:





I prefer the GT-FC40 in the L6, well, what can I do. I simply prefer it. I'm not a fan of cold tints, but this one is such a clean, low blue, no tint shift that I'm leaning towards it.

Please note, the flashlight is not suitable for placing on a desk! Once when I wanted to turn on the lamp, I bumped it, and it flipped onto the computer pad, which fell on the floor. You know, it might have broke.
From my other findings: the flashlight is well balanced, the center of gravity is right where you hold it, which makes it easier to walk with - that's significant considering it weighs 745 grams.
If I worked as a security guard, watchman, janitor, etc, I would definitely take it with me. Because of the weight and dimensions, a good flashlight for more stationary tasks. Also good to put on a shelf with your collection.
...
A few days have passed, I've been using it even longer and I took it into the woods again and I'll tell you this: this flashlight rocks! The concentrated light beam pierced the forest. Powerful!

The Convoy L6 is a flashlight well known to fans of the brand. Now we see it in a refreshed version, when it got a new diode: GT-FC40 12V with two tints available - warm and cool. Both tints have a high CRI, as high as 90, and can also boast the lack of tint shift. And the brightness? It is also something to brag about, because we get max ~ 3400lm. All this is locked in a heavy, durable casing - the head with decent cooling, knurled tube for 2x 26650 cells, and a forward type switch outlines the tactical purpose of the flashlight.

Pros:
+ lack of tint shift
+ What a power!

Cons:
- Rattling cells in the tube,
- Heavy- 550 grams of flashlight itself

About host - threads, knurling o-rings and so on
Rating: 8/10 

About light - UI, tint and so on
Rating: 9,5/10

1 - very bad flashlight hurts to look at, terrible quality, unable to normal use 
5 - average flashlight, at a reasonable price - for the average person "great". I expect all flashlights from brands like Convoy, Astrolux, Armytek, Sofirn, Nitecore, Lumintop to get a rating > 5, while good and recommendable flashlights to get rating in the range of 7.5 - 10.
10 - flashlight meets all my expectations in a given category (e.g EDC, headlamp, thrower), it's durable and neatly made, perfect light tint, worth its (even slightly inflated) price - just pure perfect.
