Bought a XINTD C8 from Int'l Outdoor Store and Hank was kind enough to provide me with the picture of the driver(I have yet to receive the light).
Thanks in advance
I saw this driver from LCK-LED
V10
Item Price: $6.00 $5.52
Constant Current LED Driver Board - 5 Mode, 3.3-4.5V 3.0A
Description:
- Accepts one Li-ion (e.g. 18650)
- Direct drive P7 LED
- 10% 45% 100%
- High frenqency PWM
- 17mm diameter PCB
- Gold plated PCB for superior conductivity
Dimension: Diameter 16-17mm*Height 4.5mm
Input Voltage: 3.2-4.5V
Output current: 100-3500mA
Modes: High/Mid/Low/Strobe/SOS
Testing CSX0I P7 LED
Vin(V) Iout(A)
4.1 3.3
4.0 3
3.9 2.9
3.8 2.7
3.7 2.3
3.6 2
3.5 1.7
3.4 1.4

Does anyone have this driver or could compare it with V10+?
Hi oldbobk
When did you order yours?
Considering how well engineered the XinTD looks, I would be suprised if they didn't test out the drivers before they used them. Seriously, the light looks like it was built by a Flashaholic, or at least someone who understands the concept. 
I have one on order, if the driver fails, I will put in a 105C.
Is it the same with LCK-LED driver or the XINTD C8 have an updated and improved driver being a +?
I still have high hopes on the driver of this new lights.
Hello!
I presume the driver being discussed here is this one:

Looks neat, although with blinkies. 
I wonder how good would this be for S2/S2+ hosts, I see in-series current limiting resistors which could be swapped to fine tune output current. Any idea about the PWM frequency?
Cheers fellows ^:)
