Now I arranged my time to write a "full" review of this light I got from Lightscastle. It is quite easy to compare it with the noname 7-up I have.
It came in a nice colorfull sturdy package - seems to be a genuine trustfire, none of my lights came like that. Maybe because of I buy the head only. Package contained 3 o-rings, head, 6 cell battery, 1A 8.4V usual "charger"a short manual with some tech data included, warranty card and a QC card wit a date - April 11th 2014 - as hot as it can be
I would say the light is water resistant (IPX4) but can also be made waterproof with some silicone at the seals.
The head can absorb and dissipate heat better than my 7-up. The downside is the weight ~358grams - additional ~80g more! But if someone doesn't mind the weight the light puts out a decent light and can run cooler even in lower speeds. On high mode it takes 4.22A @ 7.4V - I need to measure the 7-up at that voltage to see if there is any difference. The mount is a classic plastic used by many of lights out there. It can be removed and light can be used in a tripod as a camping light where it will perform better than the 7-up due to its body mass. Anyway the head quality is one of the best among Chinese lights and also the build of other components is quite fine. Grey body consists of 3 pieces screwed/pressed together. The driver is easily accessible from the back and is quite small comparing it with the 7-up - one mosfet instead of five a beefy inductor coil and two caps are the main components. And a funny 6 colorfull leds at the back of the light where the mode button resides. A bit useless for me but it is there. LEDs are an XM-L2 but come sort of cool white (light yellow led die). Wire gauge to the leds is also decent. Soldering pretty good too. The leds on the head can be pushed far more but that would need a driver change (some 100W from pcb-components.de or similar). Reflector is a smooth one with a rose pattern and is screwed from the back of the light with 2 screws. There is some thermal glue between the leds and head body.
The UI starts from HIGH-MED-LOW-OFF with hidden strobe - thumbs up for that hidden mode! Stepless will be a nice feature and prolly can be done but most of the crucial components are sanded off any identification. We have some rain now so no beamshots yet but the pattern is similar to the 7-up. I'll update that also.
The battery pack is a 6 cell thing quite heavy in rugged silicone cover and in a carry bag with straps - the whole package the light came in is about 1100grams! It came precharged to 7.7V I didn't test the pack just opened it and saw some 1800mAh cells in 2p3s (5400mAh) - near to advertised 6000mAh. If that is true - and it seems to be it is a nice pack seeing some 700mAh cells around

We'll figure that out with my hobby charger. The manual states the light can operate 2.5hrs on high but I doubt. Then it should be some 10000mAh pack. I would expect about 1.25hrs runtime on high but that is a decent time with 32Watts on leds.The only issue is the heatshrink wrapping the cells is cracked on some spots. Connectors on head and pack seem to fil very well together. The pack has also a protection circuit so it should kick in if something goes wrong.
Overall it is a decent light very similar to my 7-up. If someone is looking for an all-in-one package and as long as someone doesn't mind the weight of the whole set. 7-up is more a compact light than this D014 - 2 cm shorter and also little thinner at the back.
I'll update the comparison with the 7-up - draw, reflector, beamshots and test the battery pack. If I am right this light is a dedicated bar light - a monster flood & spill exactly as the 7-up - just need to check the reflectors. On MED & HIGH no need of any helmet light

Guys let me know if I didn't mention something important that you like to read about it and I will update it here. For now some couple of shots I made inside playing with the light:
