Strong output
With a xml Led the light will be stronger than with a BLF-A6 driver. Real good to feed an Osram-12w-LED.

Great value for the price, ok build quality (however had to round a little bit the sharp edges)
CONS
According to the description: Rotate the four stars to the bottom of the PCB: Connect the 1st star from the left to ground: 3-mode: Hi > Lo > Strobe Connect the 2nd star from the left to ground: 2-m
Great value for the price, however I was dissappointed with the mode group arrangement differing from the description which added extra work and testing (trial and error). Fast shipping!

Драйвер как драйвер
CONS
Не работает должным образом
Припаял диод, поставил в фонарь на термопасту, проверял высокотоковым аккумулятором. Почему то не работает на макс. режиме , сбрасывает на минимум и моргает постоянно

Tailcap current is much higher than this Nanjg 105C. https://www.fasttech.com/products/1122302
CONS
Still not full rated current. The best I've seen yet though.
I have a flashlight, with XML2-T6 and a single Soshine 18650 2800mAh. With this driver I was able to achieve the highest tailcap current yet, running off a single battery. My Nanjg 105C, rated at 2.8A... (read full review)
