Have you followed the instructions in THIS THREAD ??
If not, read it & follow the instructions step by step & in order.
If you will do this, chances are your lights will work just fine. 
Edit: The light is not a bad design & the QC is actually pretty good.
Do what I told you & there is about a 99.999% chance all you FW3A’s will be working just fine… just like everybody else’s are.
And yeah… it get’s hot real fast on Turbo. The FW3A is not designed for extended Turbo run times.
