If you have an Ocean State Job Lot in the area, they have 4100 lumen, 48" LED shop light's on sale for $14.99. In addition there's also 20% off until the 26th.
That brings the cost to around $11.00 each. They're nicely made and can be ganged if necessary. So far I've purchased 8 and have them throughout the shop and seem to be working well.
Its the best deal that I've seen on these anywhere. Just thought I'd post a heads up if you looking to upgrade to LED's.
