I think you mean lighting done wrong.

If the lighting fixture was not going to be enclosed inside a hood or canopy I don't think you needed to go thru the trouble of installing the ventilation duct and fan. You could have just hung the light up and left a little space from the ceiling.

not mention the whole thing hanging from chained together plastic zip ties
