Hi,
@robincnn. I just used the 16/3 cable to get power to the rig, then solid-core 18 gauge wire to wire up the COBs.
I couldn't get the Kingbrite reflectors to mount. The lip of the base of the reflectors, where the reflector attaches to the reflector adaptor, is too wide. It conflicts with the electrical lead housings on the COB holder.

The margin outside of the attachment points for the holder clips is wider in the Kingbrite reflector.
The LEDiL reflector is narrow enough to fit down in between the lead holders on the COB holder:

Whereas the Kingbrite reflector sits on top of these parts and the attachment clips in the reflector adapter can't reach up in to the reflector to clip in:

Because the Kingbrite reflector base is wider and sits on top of the electrical lead housings, the clips can't reach up in to the reflector and engage:
