Many thanks for the feedback and some good points. Yes 100% wireless, no wires at all for safety reasons, yes I don't mind using 1 x Puck per LED flower, that would be fine.
If you have any suggested drawings or links please do send them.
I am making similar to below, which was made around 5 years ago by the looks of the technology - https://www.fitlighttraining.com/
My budget to make it all is $500, less if possible. - Cheers Jonathan
