I received the Supfire M6-T6X3 from the BLF Group Buy today, and thought I would post a first impression review for those who have not received their light yet.
The packaging was a simple box, with only a bubble wrap sleeve around the light and wrist lanyard. No other packing material or instructions were included.
On inspecting the light itself, finish is nice for this price range of light. The threads were pretty well done, with a small amount of lube. I believe they will be smoother feeling with a bit more lube, but I haven’t gotten to that yet.
The reflector configuration is very similar to the Sky Ray King, and the lens does not seem to be coated. The LEDs are pretty well centered, and the opening at the bottom of the reflectors is slightly smaller than in the King. Reflector depth looks slightly deeper than the SRK, but I have not actually taken the light apart to measure this.
Length is slightly greater than the SRY, and my sample measures 142mm. The Supfire has a mounting point on the side opposite the switch, and it will fit a standard tripod mount. I doubt that it was intended for a handle because of the placement.
The feel in the hand is surprisingly good, considering the weight with four batteries installed. Weight without batteries is 15.3 ounces, and with batteries is 22 ounces.
The user interface is relatively user friendly, with 5 modes (H, M, L, and two blinkies). There is no memory that I have found, and the light starts in high mode. When the light is on, presses on the button will cycle through all the modes, including blinky. After this full cycle the next press turns the light off. I was at first very unhappy to have to cycle all the modes to turn the light off, but I then discovered that the light can be turned off in any mode by simply pressing and holding the button for a couple of seconds. It still starts in high regardless of which mode it was previously in however.
I am including a beam shot comparing the Supfire with the Sky Ray King (at least my version of the SRK 
). The Supfire M6 seems a bit brighter than the SRK to me, with a more intense hotspot. The beam is also a bit whiter than the SRK, which I find more pleasing to my eye.
In this beam comparison photo the Sky Ray King is on the left, and the Supfire is on the right.
The Supfire M6 will take both short and long 18650 cells. I tried Panasonic 3100 non-protected, and Trustfire Flame protected, and both work fine. Here is a photo with two of each type of cells to give a better perspective of the length difference (disclaimer: don’t use different type batteries together in the same light).
Overall, I like this light so far. I will get into more depth as time allows, and maybe add a couple more photos.
Thanks,
Jim
