I am replacing 4foot Flourscent fixtures with two foot LED fixtures. The existing fixtures are hung with jack chain. I hung a couple new ones using the existing chain drops. The chain does not go straight down now but at a angle because of the shorter fixture. Should I have any concerns besides how it looks? They are about 30 feet to bottom of fixture and do not look bad besides the fact that I am used to things being straight. If I add new drops the old drops will be visible or the holes will be and may look odd as well.
