I replaced all the 4ft. fixtures in my garage & basement, which I put in soon after we bought this joint, with the old porcelain fixtures with screw-in LEDs. I put a couple of those winged lights down there, too. Best thing I ever did. I hate a dark basement, probably because the huge house I grew up in had like maybe 4 15-40 watt bulbs, one for each room of the basement, and it was scary! Parents grew up in the depression, so every penny counted even in the '60s when Dad gave us everything we needed. A watt here, a watt there; it added up to a great childhood!
