Costco had these for $32 in the coupon book that just expired, but they sold out of them really fast and then the dockworker's slowdown prevented restocking.
They are now getting shipments of them. I went there today with a raincheck and they said that they had gotten 180 of them and sold them all in three hours. They had two left that someone had returned unopened.
These are a really nice alternative to fluorescent tube shop light. Very low profile.
You can also buy LED tubes for existing shop lights you just have to rewire them to bypass the ballast.
