Hello forum members, here it go my first review of a flashlight. This time the especimen was given by Janekim at Yourui Store on Alibaba to review.
Well, since the flashlight info is quite scarse on the page I manage to gather all the data possible with the tools I have and the help of the vendor who ask the manufacturer for the missing info.
Please forgive me about grammar errors or misspelling since english is not my native language.
Heres is the flashlight itself . Even if I haven´t a Convoy S2 to compare, as you can see it is a close clone of it.
The flashlight seems fair well made and the finish look is nice. It fits on the budget side of flashlights with lots of mod potential.
Since it have an integrated led shelf that almost instantaneously drive heat to the head and body, a DTPPCB is a must.
The driver is listed up to 2500mah but I guess some changes will be needed like, bypass the driver and switch springs, and maybe go with 22AWG wires.
Also there are available AR coated glass lenses at FT and for more throw also the led can be dedomed.
Hope this first review help someone. Enjoy
