Last year I replaced my florescent lights in my garage with 48" LED fixture that I bought at Costco but I had a dark spot in the center because there is a heating duct and an I-beam that didn't allow lights to be placed in that area. I think that I then paid about $30 for them and now they are on sale for $24: 2-pack- http://www.costco.com/4%E2%80%99-Lin...&storeId=10301
The recent ones (#73883) have plug in connectors to allow them to be daisy chained and also they have pull chain switches. The earlier ones (#73993) did not. These lights are very bright and consume only 42 watts each, about 1/2 of what a florescent shop light uses.
I had on hand 4 Harbor Freight tool magnets that they sometimes offer for free: http://www.harborfreight.com/18-in-m...der-61199.html
I removed the 8 magnets from each and placed them on the rear of the fixtures to hold them to the I-beam.
Sorry, my Wing is not in the photo because it's parked in my shed building.
