Recommendations for 4" slim LED pot lights
The guy on the Home Renovision Youtube channel recommends the RENO brand, says these are built to the better quality level with stronger spring clips etc: https://renolighting.com/product/reno-3-s9w-345kwh/
But spec sheet says 9W is only good for 550 lumens of output, while most Amazon sellers are claiming 750 lumens for the same 9W. Are those just bogus claims?
Also any recommendations on spacing for a basement with 7.5" ceilings? Lots of websites recommend every 4' but that seems like a lot.
