I bought 8 x LED parcans about 2 years ago from China. After failing a PAT test I opened them up to find that the earth was not connected and the mounting of the PCB was dodgy (holes did not line up, half of the screws missing, screws inserted at an angle to cope with mis-alignment). Thankfully, I had plenty of time during covid to fix them up. I have used them twice and found that the light output is OK. It should also be noted that one had a faulty keypad and after submitting a fault report I was sent a replacement unit.
