Two Sylvania (FB40CW-6) and one GE (F40CW-U-6) 40 watt U-shaped fluorescent tubes. They're about 10.25" long and about 7.25" wide. We have no way to test these, but I assume they're in working order. (My husband just came home and told me he took those tubes out of his old office and they'd barely been used, so they should work fine.) Easy pickup in Skokie, near the library. Cross-posted.
