Love the lights, I went with the 9” for a 8’ ceiling above dining table the 7” style would have been fine too (went shorter on the cords). reason for a 4 rating is directions do not say to not cut the cord prior to feeding through the base. If you do that it won’t feed through the hole as end has a taper (had to remove the material covered cord to feed it through) luckily the black cord matches other 2 cords with material.
