You need to mount one of those electrical boxes to the ceiling first. Typically square or circular and made of galvanized steel. There are also plastic ones, I believe.
These are a must and they help disperse heat.
>>I have a wood cage made out of 3/4 inch oak. I would like to use Keyless Porcelin fixtures mounted to the ceiling. It looks like the wires would be flush with the ceiling on these. Any suggestions on mounting these? Do I need some king of spacer in between them?
