Well, got started hanging some 4' twin fixtures at home. Just found Sams club has twin 4'led fixtures for $36 each. 6 were $231.00 with tax. They pull 40 watts, 4200 lumens output,5k light, pull chain , & 5'cord. Have a pretty sturdy aluminum housing which I attached to ceiling perimeters with only 1 screw through side.Same lights were over $50 on amazon.
Also hung 3 twin t-8 fixtures with daylight bulbs,
For comparison , the daylight t-8 bulbs are a little easier on the eyes, especially on my low ceilings, but the led fixtures rated at 4200 lumens put out way the hell more light than 2 fluorescent bulbs rated at 5600 lumens per pair. Much whiter cleaner light.
Will probably pick up about 6 more tomorrow, along with some smaller led fixtures .
