I was sent this light by Neville, who got four of them at the same time, but three failed after a small amount of use.
The design looks fairly typical for these, but there are a few design flaws, and the PCB seems designed for a group of three NiMh cells instead of the 18650 lithium cell fitted.
The transistor that switches the LEDs is indeed a MOSFET (A2SHB). The PIR sensor looks like a standard one, but has extra circuitry in its case.
The general build quality, cell holder, LED arrays and solar panel all seem good. Shame about the PCB design.
