in 2010 I wired my shop with T-12 fluorescent shop lights plugged into ceiling outlets because that was the cheapest option. Over the years most of the ballasts failed so I had several non-working fixtures. This summer I converted them to direct wire LED fluorescent replacements. The direct wire LED's cost $5.00 each at Lowes if you buy a box of 20. Conversion takes about 10 min. and a couple wire nuts. Light is brighter and more white, a definate improvement for $10.00 per fixture.
