Review on HLB6099FS1EMWR Selectable Construction Recessed Integrated by Darryl Pendall

I wasn't sure if the electrical box should touch the insulation or be mounted higher on the truss or rafters. The instructions say "install the box according to local electrical codes" which is utterly useless to the DIYer. I ended up putting the box on the truss just for safety, but that limited where I could place the light because the cable from the box to the light is short.
